*activity_notification* provides integrated user activity notifications for [Ruby on Rails](https://rubyonrails.org). You can easily use it to configure multiple notification targets and make activity notifications with notifiable models, like adding comments, responding etc.
*activity_notification* supports Rails 7.0+ with [ActiveRecord](https://guides.rubyonrails.org/active_record_basics.html), [Mongoid](https://mongoid.org) and [Dynamoid](https://github.com/Dynamoid/dynamoid) ORM. It is tested for [MySQL](https://www.mysql.com), [PostgreSQL](https://www.postgresql.org), [SQLite3](https://www.sqlite.org) with ActiveRecord, [MongoDB](https://www.mongodb.com) with Mongoid and [Amazon DynamoDB](https://aws.amazon.com/dynamodb) with Dynamoid v3.11.0+. If you are using Rails 5 or Rails 6, use [v2.3.3](https://rubygems.org/gems/activity_notification/versions/2.3.3) or older version of *activity_notification*.
## About
*activity_notification* provides following functions:
* Notification API for your Rails application (creating and managing notifications, query for notifications)
* Notification models (stored with ActiveRecord, Mongoid or Dynamoid ORM)
* Notification controllers (managing open/unopen of notifications, providing link to notifiable activity page)
* Notification views (presentation of notifications)
* Automatic tracked notifications (generating notifications along with the lifecycle of notifiable models)
* Grouping notifications (grouping like *"Kevin and 7 other users posted comments to this article"*)
* Email notification
* Email attachments (configurable at global, target, and notifiable levels)
* Batch email notification (event driven or periodical email notification, daily or weekly etc)
* Cascading notifications (progressive notification escalation through multiple channels with time delays)
* Push notification with [Action Cable](https://guides.rubyonrails.org/action_cable_overview.html)
* Subscription management (subscribing and unsubscribing for each target and notification type)
* Instance-level subscriptions (subscribing to notifications from a specific notifiable instance)
* REST API backend and [OpenAPI Specification](https://github.com/OAI/OpenAPI-Specification)
* Integration with [Devise](https://github.com/plataformatec/devise) authentication
* Activity notifications stream integrated into cloud computing using [Amazon DynamoDB Streams](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.html)
* Optional notification targets (Configurable optional notification targets like [Amazon SNS](https://aws.amazon.com/sns), [Slack](https://slack.com), SMS and so on)
### Notification index and plugin notifications
*activity_notification* deeply uses [PublicActivity](https://github.com/pokonski/public_activity) as reference in presentation layer.
### Subscription management of notifications
### Amazon SNS as optional notification target
### Slack as optional notification target
### Public REST API reference as OpenAPI Specification
REST API reference as OpenAPI Specification is published in SwaggerHub here:
* **https://app.swaggerhub.com/apis-docs/simukappu/activity-notification/**
You can see sample single page application using [Vue.js](https://vuejs.org) as a part of example Rails application in *[/spec/rails_app](/spec/rails_app/)*. This sample application works with *activity_notification* REST API backend.

## Getting Started
This getting started shows easy setup description of *activity_notification*. See [Setup](/docs/Setup.md#Setup) for more details.
### Gem installation
You can install *activity_notification* as you would any other gem:
```console
$ gem install activity_notification
```
or in your Gemfile:
```ruby
gem 'activity_notification'
```
After you install *activity_notification* and add it to your Gemfile, you need to run the generator:
```console
$ bin/rails generate activity_notification:install
```
The generator will install an initializer which describes all configuration options of *activity_notification*.
#### ORM Dependencies
By default, *activity_notification* uses **ActiveRecord** as the ORM and no additional ORM gems are required.
If you intend to use **Mongoid** support, you need to add the `mongoid` gem separately to your Gemfile:
```ruby
gem 'activity_notification'
gem 'mongoid', '>= 4.0.0', '< 10.0'
```
If you intend to use **Dynamoid** support for Amazon DynamoDB, you need to add the `dynamoid` gem separately to your Gemfile:
```ruby
gem 'activity_notification'
gem 'dynamoid', '>= 3.11.0', '< 4.0'
```
### Database setup
When you use *activity_notification* with ActiveRecord ORM as default configuration,
create migration for notifications and migrate the database in your Rails project:
```console
$ bin/rails generate activity_notification:migration
$ bin/rake db:migrate
```
See [Database setup](/docs/Setup.md#database-setup) for other ORMs.
### Configuring models
Configure your target model (e.g. *app/models/user.rb*).
Add **acts_as_target** configuration to your target model to get notifications.
```ruby
class User < ActiveRecord::Base
acts_as_target
end
```
Then, configure your notifiable model (e.g. *app/models/comment.rb*).
Add **acts_as_notifiable** configuration to your notifiable model representing activity to notify for each of your target model.
You have to define notification targets for all notifications from this notifiable model by *:targets* option. Other configurations are optional. *:notifiable_path* option is a path to move when the notification is opened by the target user.
```ruby
class Article < ActiveRecord::Base
belongs_to :user
has_many :comments, dependent: :destroy
has_many :commented_users, through: :comments, source: :user
end
class Comment < ActiveRecord::Base
belongs_to :article
belongs_to :user
acts_as_notifiable :users,
targets: ->(comment, key) {
([comment.article.user] + comment.article.reload.commented_users.to_a - [comment.user]).uniq
},
notifiable_path: :article_notifiable_path
def article_notifiable_path
article_path(article)
end
end
```
See [Configuring models](/docs/Setup.md#configuring-models) for more details.
### Configuring views
*activity_notification* provides view templates to customize your notification views.
See [Configuring views](/docs/Setup.md#configuring-views) for more details.
### Configuring routes
*activity_notification* also provides routing helper for notifications. Add **notify_to** method to *config/routes.rb* for the target (e.g. *:users*):
```ruby
Rails.application.routes.draw do
notify_to :users
end
```
See [Configuring routes](/docs/Setup.md#configuring-routes) for more details.
You can also configure *activity_notification* routes as REST API backend with *api_mode* option like this:
```ruby
Rails.application.routes.draw do
scope :api do
scope :"v2" do
notify_to :users, api_mode: true
end
end
end
```
See [Routes as REST API backend](/docs/Setup.md#configuring-routes) and [REST API backend](/docs/Functions.md#rest-api-backend) for more details.
### Creating notifications
You can trigger notifications by setting all your required parameters and triggering **notify** on the notifiable model, like this:
```ruby
@comment.notify :users, key: "comment.reply"
```
The first argument is the plural symbol name of your target model, which is configured in notifiable model by *acts_as_notifiable*.
The new instances of **ActivityNotification::Notification** model will be generated for the specified targets.
See [Creating notifications](/docs/Setup.md#creating-notifications) for more details.
### Displaying notifications
*activity_notification* also provides notification views. You can prepare target notifications, render them in your controller, and show them provided or custom notification views.
See [Displaying notifications](/docs/Setup.md#displaying-notifications) for more details.
### Managing notifications
*activity_notification* provides APIs to manage notifications programmatically. You can mark notifications as opened (read), filter them, and perform bulk operations.
See [Managing notifications](/docs/Setup.md#managing-notifications) for more details.
### Run example Rails application
Test module includes example Rails application in *[spec/rails_app](/spec/rails_app)*.
Pull git repository and you can run the example application as common Rails application.
```console
$ git pull https://github.com/simukappu/activity_notification.git
$ cd activity_notification
$ bundle install —path vendor/bundle
$ cd spec/rails_app
$ bin/rake db:migrate
$ bin/rake db:seed
$ bin/rails server
```
Then, you can access for the example application.
## Setup

FILE: ai-docs/ROADMAP.md
================================================
# Development Roadmap (post v2.6.0)
## Short-term
### Remove `jquery-rails` dependency
- `jquery-rails` is required in `lib/activity_notification/rails.rb` but Rails 7+ does not include jQuery by default
- The gem's views use jQuery for AJAX subscription management
- Migrate view JavaScript to Vanilla JS or Stimulus, then make `jquery-rails` optional
- This is the most impactful cleanup for modern Rails applications
### Review `swagger-blocks` dependency
- `swagger-blocks` is used for OpenAPI spec generation in API controllers
- Consider migrating to static YAML/JSON OpenAPI spec files or a more actively maintained library
- This would simplify the codebase and reduce runtime dependencies
## Medium-term
### Soft delete integration guide for notifiables
- Issue #140 requested `:nullify_notifiable` for `dependent_notifications`, but the design conflicts with Notification's `validates :notifiable, presence: true`
- Instead of modifying the gem, document integration patterns with `paranoia` or `discard` gems
- Add a section to Functions.md showing how soft-deleted notifiables work with notifications
### Configurable subscription association name
- Issue #161 requested renaming the `subscriptions` association to avoid conflicts with application models (e.g., billing subscriptions)
- Add an option to `acts_as_target` like `subscription_association_name: :notification_subscriptions`
- This avoids a breaking change while solving the conflict
## Long-term
### Turbo Streams support
- Current push notifications use Action Cable channels with custom JavaScript
- Rails 8 applications increasingly use Turbo Streams for real-time updates
- Add optional Turbo Streams broadcasting as an alternative to the current Action Cable channels
### Async notification batching
- Current `notify_later` serializes all targets into a single job
- For very large target sets (10,000+), split into chunked jobs that process targets in batches
- This would improve memory usage and job queue throughput

# CC (Carbon Copy) Feature Implementation
## Overview
The CC (Carbon Copy) functionality has been added to the activity_notification gem's email notification system. This feature allows email notifications to be sent with additional CC recipients, following the same pattern as existing email header fields like `from`, `reply_to`, and `to`.
CC recipients can be configured at three levels:
1. **Global configuration** - Set a default CC for all notifications via the gem's configuration file
2. **Target model** - Define CC recipients at the target level (e.g., User, Admin)
3. **Notifiable model** - Override CC per notification type in the notifiable model
## Implementation Details
### Files Modified
1. **lib/activity_notification/config.rb**
- Added `mailer_cc` configuration attribute to allow global CC configuration
- Supports String, Array, or Proc values for flexible CC recipient configuration
2. **lib/activity_notification/mailers/helpers.rb**
- Added `cc: :mailer_cc` to the email headers processing loop in the `headers_for` method
- Updated the `mailer_cc` helper method to check configuration when target doesn't define mailer_cc
- Updated the header value resolution logic to properly handle the `mailer_cc` method which takes a target parameter instead of a key parameter
3. **lib/generators/templates/activity_notification.rb**
- Added configuration example and documentation for `config.mailer_cc`
### Key Features
- **Three-Level Configuration**: CC can be configured at the global level (gem configuration), target level (model), or notification level (per-notification type)
- **Flexible CC Recipients**: CC can be specified as a single email address (String), multiple email addresses (Array), or dynamic via Proc
- **Optional Implementation**: All CC configuration is optional - if not defined, no CC recipients will be added
- **Override Support**: Like other email headers, CC can be overridden per notification using the `overriding_notification_email_cc` method in the notifiable model
- **Consistent Pattern**: Follows the same implementation pattern as existing email headers (`from`, `reply_to`, `to`)
## Usage Guide
### Method 1: Configure CC Globally (New Feature)
Set a default CC for all notification emails in your initializer:
```ruby
# config/initializers/activity_notification.rb
ActivityNotification.configure do |config|
# Single CC recipient for all notifications
config.mailer_cc = 'admin@example.com'
# OR multiple CC recipients
config.mailer_cc = ['admin@example.com', 'support@example.com']
# OR dynamic CC based on notification key
config.mailer_cc = ->(key) {
if key.include?('urgent')
['urgent@example.com', 'manager@example.com']
else
'admin@example.com'
end
}
end
```
### Method 2: Define `mailer_cc` in Your Target Model
Add a `mailer_cc` method to your target model (e.g., User, Admin) to specify CC recipients for that target. This overrides the global configuration:
```ruby
class User < ApplicationRecord
acts_as_target
# Return a single CC email address
def mailer_cc
"admin@example.com"
end
# OR return multiple CC email addresses
def mailer_cc
["admin@example.com", "manager@example.com"]
end
# OR conditionally return CC addresses
def mailer_cc
return nil unless self.team_lead.present?
self.team_lead.email
end
end
```
### Method 3: Override CC Per Notification Type
For more granular control, implement `overriding_notification_email_cc` in your notifiable model to set CC based on the notification type. This has the highest priority:
```ruby
class Article < ApplicationRecord
acts_as_notifiable
def overriding_notification_email_cc(target, key)
case key
when 'article.commented'
# CC the article author on comment notifications
self.author.email
when 'article.published'
# CC multiple recipients for published articles
["editor@example.com", "marketing@example.com"]
else
nil # Use target's mailer_cc or global config
end
end
end
```
### Method 4: Combine All Approaches
You can combine all approaches - the priority order is: notification override > target method > global configuration:
```ruby
# config/initializers/activity_notification.rb
ActivityNotification.configure do |config|
# Global default for all notifications
config.mailer_cc = "support@example.com"
end
class User < ApplicationRecord
acts_as_target
# Override global config for this target
def mailer_cc
"admin@example.com"
end
end
class Comment < ApplicationRecord
acts_as_notifiable
# Override both global config and target method for specific notifications
def overriding_notification_email_cc(target, key)
if key == 'comment.urgent'
["urgent@example.com", "manager@example.com"]
else
nil # Falls back to target.mailer_cc, then global config
end
end
end
```
## Examples
### Example 1: Global Configuration with Static CC
```ruby
# config/initializers/activity_notification.rb
ActivityNotification.configure do |config|
config.mailer_cc = "admin@example.com"
end
# All notification emails will include:
# To: user@example.com
# CC: admin@example.com
```
### Example 2: Global Configuration with Multiple CC Recipients
```ruby
# config/initializers/activity_notification.rb
ActivityNotification.configure do |config|
config.mailer_cc = ["supervisor@example.com", "hr@example.com"]
end
# All notification emails will include:
# To: user@example.com
# CC: supervisor@example.com, hr@example.com
```
### Example 3: Dynamic Global CC Based on Notification Key
```ruby
# config/initializers/activity_notification.rb
ActivityNotification.configure do |config|
config.mailer_cc = ->(key) {
case key
when /urgent/
["urgent@example.com", "manager@example.com"]
when /comment/
"moderation@example.com"
else
"admin@example.com"
end
}
end
```
### Example 4: Target-Level Static CC
```ruby
class User < ApplicationRecord
acts_as_target
def mailer_cc
"admin@example.com"
end
end
# When a notification is sent, the email will include:
# To: user@example.com
# CC: admin@example.com
```
### Example 5: Target-Level Multiple CC Recipients
```ruby
class User < ApplicationRecord
acts_as_target
def mailer_cc
["supervisor@example.com", "hr@example.com"]
end
end
# Email will include:
# To: user@example.com
# CC: supervisor@example.com, hr@example.com
```
### Example 6: Dynamic CC Based on User Attributes
```ruby
class User < ApplicationRecord
acts_as_target
belongs_to :department
def mailer_cc
cc_list = []
cc_list << self.manager.email if self.manager.present?
cc_list << self.department.email if self.department.present?
cc_list.presence # Returns nil if empty, otherwise returns the array
end
end
```
### Example 7: Override CC Per Notification
```ruby
class Article < ApplicationRecord
acts_as_notifiable
belongs_to :author
def overriding_notification_email_cc(target, key)
case key
when 'article.new_comment'
# Notify the article author when someone comments
self.author.email
when 'article.shared'
# Notify multiple stakeholders when article is shared
[self.author.email, "marketing@example.com"]
when 'article.flagged'
# Notify moderation team
["moderation@example.com", "admin@example.com"]
else
nil
end
end
end
```
### Example 8: Conditional CC Based on Target and Key
```ruby
class Post < ApplicationRecord
acts_as_notifiable
def overriding_notification_email_cc(target, key)
cc_list = []
# Always CC the post owner
cc_list << self.user.email if self.user.present?
# For urgent notifications, CC administrators
if key.include?('urgent')
cc_list += User.where(role: 'admin').pluck(:email)
end
# For specific users, CC their team lead
if target.team_lead.present?
cc_list << target.team_lead.email
end
cc_list.uniq.presence
end
end
```
## Technical Details
### Resolution Order
The CC recipient(s) are resolved in the following priority order:
1. **Override Method** (Highest Priority): If the notifiable model has `overriding_notification_email_cc(target, key)` defined and returns a non-nil value, that value is used
2. **Target Method**: If no override is provided, the target's `mailer_cc` method is called (if it exists)
3. **Global Configuration**: If the target doesn't have a `mailer_cc` method, the global `config.mailer_cc` setting is used (if configured)
4. **No CC** (Default): If none of the above are defined or all return nil, no CC header is added to the email
### Return Value Format
Both the `mailer_cc` method and `config.mailer_cc` configuration can return:
- **String**: A single email address (e.g., `"admin@example.com"`)
- **Array**: Multiple email addresses (e.g., `["admin@example.com", "manager@example.com"]`)
- **Proc**: A lambda/proc that takes the notification key and returns a String, Array, or nil (e.g., `->(key) { key.include?('urgent') ? 'urgent@example.com' : nil }`)
- **nil**: No CC recipients (CC header will not be added to the email)
### Implementation Pattern
The CC feature follows the same pattern as other email headers in the gem:
```ruby
# In headers_for method
{
subject: :subject_for,
from: :mailer_from,
reply_to: :mailer_reply_to,
cc: :mailer_cc, # <-- New CC support
message_id: nil
}.each do |header_name, default_method|
# Check for override method in notifiable
overridding_method_name = "overriding_notification_email_#{header_name}"
if notifiable.respond_to?(overridding_method_name)
use_override_value
elsif default_method
use_default_method
end
end
```
## Testing
To test the CC functionality in your application:
```ruby
# RSpec example
RSpec.describe "Notification emails with CC" do
let(:user) { create(:user) }
let(:notification) { create(:notification, target: user) }
before do
# Define mailer_cc for the test
allow(user).to receive(:mailer_cc).and_return("admin@example.com")
end
it "includes CC recipient in email" do
mail = ActivityNotification::Mailer.send_notification_email(notification)
expect(mail.cc).to include("admin@example.com")
end
it "supports multiple CC recipients" do
allow(user).to receive(:mailer_cc).and_return(["admin@example.com", "manager@example.com"])
mail = ActivityNotification::Mailer.send_notification_email(notification)
expect(mail.cc).to eq(["admin@example.com", "manager@example.com"])
end
it "does not include CC header when nil" do
allow(user).to receive(:mailer_cc).and_return(nil)
mail = ActivityNotification::Mailer.send_notification_email(notification)
expect(mail.cc).to be_nil
end
end
```
## Backward Compatibility
This feature is **fully backward compatible**:
- Existing applications without `mailer_cc` defined will continue to work exactly as before
- No CC header will be added to emails unless explicitly configured
- No database migrations or configuration changes are required
- The implementation gracefully handles cases where `mailer_cc` is not defined
## Best Practices
1. **Return nil for no CC**: If you don't want CC recipients, return `nil` rather than an empty array or empty string
2. **Validate email addresses**: Ensure CC recipients are valid email addresses to avoid mail delivery issues
3. **Avoid excessive CC**: Be mindful of privacy and avoid CCing too many recipients
4. **Use override for specific cases**: Use `overriding_notification_email_cc` for notification-specific CC logic
5. **Keep it simple**: Use the target's `mailer_cc` method for consistent CC across all notifications
## Related Methods
The CC feature works alongside these existing email configuration methods:
- `mailer_to` - Primary recipient email address (required)
- `mailer_from` - Sender email address
- `mailer_reply_to` - Reply-to email address
- `mailer_cc` - Carbon copy recipients (new)
All of these can be overridden using the `overriding_notification_email_*` pattern in the notifiable model.
## Summary
The CC functionality seamlessly integrates with the existing activity_notification email system, providing a flexible and powerful way to add carbon copy recipients to notification emails. Whether you need static CC addresses, dynamic recipients based on user attributes, or notification-specific CC logic, this implementation supports all these use cases while maintaining backward compatibility with existing code.

# Cascading Notifications - Complete Implementation Example
This document provides a comprehensive example of implementing cascading notifications in a Rails application. This is primarily for AI agents implementing similar functionality.
## Scenario: Task Management Application
Users can be assigned tasks, and we want to ensure they don't miss important assignments through progressive notification escalation.
## Complete Implementation
### 1. Task Model with Cascade Configuration
```ruby
# app/models/task.rb
class Task < ApplicationRecord
belongs_to :assignee, class_name: 'User'
belongs_to :creator, class_name: 'User'
validates :title, :description, :due_date, presence: true
# Configure as notifiable with optional targets
require 'activity_notification/optional_targets/slack'
require 'activity_notification/optional_targets/amazon_sns'
acts_as_notifiable :users,
targets: ->(task, key) { [task.assignee] },
notifiable_path: :task_notifiable_path,
group: :project,
notifier: :creator,
optional_targets: {
ActivityNotification::OptionalTarget::Slack => {
webhook_url: ENV['SLACK_WEBHOOK_URL'],
target_username: :slack_username,
channel: '#tasks',
username: 'TaskBot',
icon_emoji: ':clipboard:'
},
ActivityNotification::OptionalTarget::AmazonSNS => {
phone_number: :phone_number
}
}
def task_notifiable_path
Rails.application.routes.url_helpers.task_path(self)
end
# Define cascade strategies based on task priority
def notification_cascade_config
case priority
when 'urgent'
URGENT_TASK_CASCADE
when 'high'
HIGH_PRIORITY_CASCADE
when 'normal'
NORMAL_PRIORITY_CASCADE
else
LOW_PRIORITY_CASCADE
end
end
# Cascade configurations as constants
URGENT_TASK_CASCADE = [
{ delay: 2.minutes, target: :slack, options: { channel: '#urgent-tasks' } },
{ delay: 5.minutes, target: :amazon_sns },
{ delay: 15.minutes, target: :slack, options: { channel: '@assignee' } }
].freeze
HIGH_PRIORITY_CASCADE = [
{ delay: 10.minutes, target: :slack },
{ delay: 30.minutes, target: :amazon_sns }
].freeze
NORMAL_PRIORITY_CASCADE = [
{ delay: 30.minutes, target: :slack },
{ delay: 2.hours, target: :amazon_sns }
].freeze
LOW_PRIORITY_CASCADE = [
{ delay: 2.hours, target: :slack },
{ delay: 1.day, target: :amazon_sns }
].freeze
end
```
### 2. User Model Configuration
```ruby
# app/models/user.rb
class User < ApplicationRecord
devise :database_authenticatable, :registerable
acts_as_target
def slack_username
"@#{username}"
end
def phone_number
attributes['phone_number']
end
def cascade_delay_multiplier
notification_preferences['cascade_delay_multiplier'] || 1.0
end
end
```
### 3. Service Object for Notification Management
```ruby
# app/services/task_notification_service.rb
class TaskNotificationService
def initialize(task)
@task = task
end
def notify_assignment
notifications = @task.notify(:users, key: 'task.assigned', send_later: false)
notifications.each do |notification|
apply_cascade_to_notification(notification)
end
notifications
end
def notify_due_soon
notifications = @task.notify(:users, key: 'task.due_soon', send_later: false)
notifications.each do |notification|
cascade_config = [
{ delay: 1.hour, target: :slack },
{ delay: 3.hours, target: :amazon_sns }
]
notification.cascade_notify(cascade_config, trigger_first_immediately: true)
end
notifications
end
def notify_overdue
notifications = @task.notify(:users, key: 'task.overdue', send_later: false)
notifications.each do |notification|
cascade_config = [
{ delay: 30.minutes, target: :slack, options: { channel: '#urgent-tasks' } },
{ delay: 1.hour, target: :amazon_sns },
{ delay: 2.hours, target: :slack, options: { channel: '@assignee' } }
]
notification.cascade_notify(cascade_config, trigger_first_immediately: true)
end
notifications
end
private
def apply_cascade_to_notification(notification)
cascade_config = @task.notification_cascade_config
if notification.target.respond_to?(:cascade_delay_multiplier)
multiplier = notification.target.cascade_delay_multiplier
cascade_config = adjust_delays(cascade_config, multiplier)
end
notification.cascade_notify(cascade_config)
rescue => e
Rails.logger.error("Failed to start cascade for notification #{notification.id}: #{e.message}")
end
def adjust_delays(cascade_config, multiplier)
cascade_config.map do |step|
step.dup.tap do |adjusted_step|
original_delay = adjusted_step[:delay]
adjusted_step[:delay] = (original_delay.to_i * multiplier).seconds
end
end
end
end
```
### 4. Controller Integration
```ruby
# app/controllers/tasks_controller.rb
class TasksController < ApplicationController
before_action :authenticate_user!
def create
@task = Task.new(task_params)
@task.creator = current_user
if @task.save
notification_service = TaskNotificationService.new(@task)
notification_service.notify_assignment
redirect_to @task, notice: 'Task created and assignee notified.'
else
render :new
end
end
def update
@task = Task.find(params[:id])
assignee_changed = @task.assignee_id_changed?
if @task.update(task_params)
if assignee_changed
notification_service = TaskNotificationService.new(@task)
notification_service.notify_assignment
end
redirect_to @task, notice: 'Task updated.'
else
render :edit
end
end
private
def task_params
params.require(:task).permit(:title, :description, :due_date, :priority, :assignee_id)
end
end
```
### 5. Background Job for Scheduled Reminders
```ruby
# app/jobs/task_reminder_job.rb
class TaskReminderJob < ApplicationJob
queue_as :default
def perform
check_tasks_due_soon
check_overdue_tasks
end
private
def check_tasks_due_soon
tasks = Task.where(completed: false)
.where('due_date BETWEEN ? AND ?', Time.current, 24.hours.from_now)
.where('last_reminder_sent_at IS NULL OR last_reminder_sent_at < ?', 12.hours.ago)
tasks.each do |task|
notification_service = TaskNotificationService.new(task)
notification_service.notify_due_soon
task.update_column(:last_reminder_sent_at, Time.current)
end
end
def check_overdue_tasks
tasks = Task.where(completed: false)
.where('due_date < ?', Time.current)
.where('last_overdue_reminder_at IS NULL OR last_overdue_reminder_at < ?', 6.hours.ago)
tasks.each do |task|
notification_service = TaskNotificationService.new(task)
notification_service.notify_overdue
task.update_column(:last_overdue_reminder_at, Time.current)
end
end
end
```
### 6. User Preferences Management
```ruby
# app/controllers/notification_preferences_controller.rb
class NotificationPreferencesController < ApplicationController
before_action :authenticate_user!
def edit
@preferences = current_user.notification_preferences || {}
end
def update
preferences = current_user.notification_preferences || {}
preferences.merge!(preferences_params)
if current_user.update(notification_preferences: preferences)
redirect_to edit_notification_preferences_path,
notice: 'Notification preferences updated.'
else
render :edit
end
end
private
def preferences_params
params.require(:notification_preferences).permit(
:cascade_delay_multiplier,
:enable_slack_notifications,
:enable_sms_notifications,
:quiet_hours_start,
:quiet_hours_end
)
end
end
```
### 7. Monitoring and Analytics
```ruby
# app/models/concerns/cascade_tracking.rb
module CascadeTracking
extend ActiveSupport::Concern
included do
after_update :track_cascade_effectiveness, if: :saved_change_to_opened_at?
end
private
def track_cascade_effectiveness
return unless opened?
time_to_open = opened_at - created_at
if parameters[:cascade_config].present?
cascade_config = parameters[:cascade_config]
elapsed_time = 0
active_step_index = 0
cascade_config.each_with_index do |step, index|
elapsed_time += step['delay'].to_i
if time_to_open < elapsed_time
active_step_index = index
break
end
end
track_cascade_metrics(
notification_type: key,
time_to_open: time_to_open,
cascade_step_when_opened: active_step_index,
total_cascade_steps: cascade_config.size
)
end
end
def track_cascade_metrics(metrics)
Rails.logger.info("Cascade Metrics: #{metrics.to_json}")
# AnalyticsService.track('notification_cascade_opened', metrics)
end
end
# Include in your notification model
ActivityNotification::Notification.include(CascadeTracking)
```
### 8. Testing Examples
```ruby
# spec/services/task_notification_service_spec.rb
require 'rails_helper'
RSpec.describe TaskNotificationService do
let(:creator) { create(:user) }
let(:assignee) { create(:user) }
let(:task) { create(:task, creator: creator, assignee: assignee, priority: 'urgent') }
let(:service) { described_class.new(task) }
before do
ActiveJob::Base.queue_adapter = :test
ActiveJob::Base.queue_adapter.enqueued_jobs.clear
end
describe '#notify_assignment' do
it 'creates notification with cascade' do
notifications = service.notify_assignment
expect(notifications.size).to eq(1)
expect(notifications.first.target).to eq(assignee)
end
it 'enqueues cascade jobs' do
expect {
service.notify_assignment
}.to have_enqueued_job(ActivityNotification::CascadingNotificationJob)
end
it 'uses urgent cascade for urgent tasks' do
notification = service.notify_assignment.first
expect(ActiveJob::Base.queue_adapter.enqueued_jobs.size).to be > 0
end
end
describe '#notify_due_soon' do
it 'creates notification with aggressive cascade' do
notifications = service.notify_due_soon
expect(notifications.size).to eq(1)
expect(ActiveJob::Base.queue_adapter.enqueued_jobs.size).to be > 0
end
end
end
```
## Key Implementation Patterns
1. **Service Objects**: Encapsulate notification logic with cascades
2. **Configuration Constants**: Define reusable cascade strategies
3. **User Preferences**: Allow users to customize cascade timing
4. **Background Jobs**: Handle scheduled notifications
5. **Monitoring**: Track cascade effectiveness
6. **Testing**: Comprehensive test coverage for cascade behavior
This example demonstrates a production-ready implementation of cascading notifications with proper error handling, user preferences, monitoring, and testing.

# Cascading Notifications Implementation
## Overview
The cascading notification feature enables sequential delivery of notifications through different channels based on read status, with configurable time delays between each step. This allows you to implement sophisticated notification escalation patterns, such as:
1. Send in-app notification
2. Wait 10 minutes → if not read, send Slack message
3. Wait another 10 minutes → if still not read, send email
4. Wait another 30 minutes → if still not read, send SMS
This feature is particularly useful for ensuring important notifications are not missed, while avoiding unnecessary interruptions when users have already engaged with earlier notification channels.
## Architecture
### Components
The cascading notification system consists of three main components:
1. **CascadingNotificationJob** (`app/jobs/activity_notification/cascading_notification_job.rb`)
- ActiveJob-based job that handles individual cascade steps
- Checks notification read status before triggering optional targets
- Schedules subsequent cascade steps automatically
- Handles errors gracefully with configurable error recovery
2. **CascadingNotificationApi** (`lib/activity_notification/apis/cascading_notification_api.rb`)
- Module included in the Notification model
- Provides `cascade_notify` method to initiate cascades
- Validates cascade configurations
- Manages cascade lifecycle
3. **Integration with Notification Model**
- Extends ActiveRecord, Mongoid, and Dynamoid notification implementations
- Seamlessly integrates with existing notification system
- Compatible with all existing optional targets (Slack, Amazon SNS, email, etc.)
### How It Works
```
┌──────────────────────────────────────────────────────────────────┐
│ 1. notification.cascade_notify(config) called │
└───────────────────────┬──────────────────────────────────────────┘
│
▼
┌──────────────────────────────────────────────────────────────────┐
│ 2. Validation: Check config format, required parameters │
└───────────────────────┬──────────────────────────────────────────┘
│
▼
┌──────────────────────────────────────────────────────────────────┐
│ 3. Schedule CascadingNotificationJob with first step delay │
└───────────────────────┬──────────────────────────────────────────┘
│
▼ (after delay)
┌──────────────────────────────────────────────────────────────────┐
│ 4. Job executes: │
│ - Find notification by ID │
│ - Check if notification.opened? → YES: exit │
│ - Check if notification.opened? → NO: continue │
└───────────────────────┬──────────────────────────────────────────┘
│
▼
┌──────────────────────────────────────────────────────────────────┐
│ 5. Trigger optional target for current step: │
│ - Find configured optional target │
│ - Check subscription status │
│ - Call target.notify(notification, options) │
└───────────────────────┬──────────────────────────────────────────┘
│
▼
┌──────────────────────────────────────────────────────────────────┐
│ 6. Schedule next step if available: │
│ - Check if more steps exist in config │
│ - Schedule CascadingNotificationJob with next step delay │
└──────────────────────────────────────────────────────────────────┘
```
## Configuration Options
### Cascade Configuration Structure
Each cascade is defined as an array of step configurations:
```ruby
cascade_config = [
{
delay: ActiveSupport::Duration, # Required: Time to wait before this step
target: Symbol or String, # Required: Name of optional target (:slack, :email, etc.)
options: Hash # Optional: Parameters to pass to the optional target
},
# ... more steps
]
```
### Cascade Method Options
The `cascade_notify` method accepts an optional second parameter for additional control:
```ruby
notification.cascade_notify(cascade_config, options)
```
Available options:
- `validate: Boolean` (default: `true`) - Whether to validate cascade configuration before starting
- `trigger_first_immediately: Boolean` (default: `false`) - Whether to trigger the first target immediately without waiting for the delay
## Usage Examples
### Basic Two-Step Cascade
Send a Slack notification after 10 minutes if unread, then email after another 10 minutes:
```ruby
# After creating a notification
notification = Notification.create!(
target: user,
notifiable: comment,
key: 'comment.reply'
)
# Start the cascade
cascade_config = [
{ delay: 10.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
]
notification.cascade_notify(cascade_config)
```
### Multi-Channel Escalation with Custom Options
Progressive escalation through multiple channels with custom parameters:
```ruby
cascade_config = [
{
delay: 5.minutes,
target: :slack,
options: {
channel: '#general',
username: 'NotificationBot'
}
},
{
delay: 10.minutes,
target: :slack,
options: {
channel: '#urgent',
username: 'UrgentBot'
}
},
{
delay: 15.minutes,
target: :amazon_sns,
options: {
subject: 'Urgent: Unread Notification',
message_attributes: { priority: 'high' }
}
},
{
delay: 30.minutes,
target: :email
}
]
notification.cascade_notify(cascade_config)
```
### Immediate First Notification
Trigger the first target immediately, then cascade to others if still unread:
```ruby
cascade_config = [
{ delay: 5.minutes, target: :slack }, # Ignored delay, triggered immediately
{ delay: 10.minutes, target: :email }
]
notification.cascade_notify(cascade_config, trigger_first_immediately: true)
```
### Integration with Notification Creation
Combine cascade with standard notification creation:
```ruby
# In your notifiable model (e.g., Comment)
class Comment < ApplicationRecord
acts_as_notifiable :users,
targets: ->(comment, key) { ... },
notifiable_path: :article_path
# Optional: Define cascade configuration
def notification_cascade_config
[
{ delay: 10.minutes, target: :slack },
{ delay: 15.minutes, target: :email }
]
end
end
# In your controller or service
comment = Comment.create!(params)
comment.notify(:users, key: 'comment.new')
# Start cascade for each notification
comment.notifications.each do |notification|
notification.cascade_notify(comment.notification_cascade_config)
end
```
### Conditional Cascading
Apply different cascade strategies based on notification type or priority:
```ruby
def cascade_notification(notification)
case notification.key
when 'urgent.alert'
# Aggressive escalation for urgent items
cascade_config = [
{ delay: 2.minutes, target: :slack },
{ delay: 5.minutes, target: :email },
{ delay: 10.minutes, target: :sms }
]
when 'comment.reply'
# Gentle escalation for comments
cascade_config = [
{ delay: 30.minutes, target: :slack },
{ delay: 1.hour, target: :email }
]
else
# Default escalation
cascade_config = [
{ delay: 15.minutes, target: :slack },
{ delay: 30.minutes, target: :email }
]
end
notification.cascade_notify(cascade_config)
end
```
### Using with Asynchronous Notification Creation
When using `notify_later` (ActiveJob), cascade after notification creation:
```ruby
# Create notifications asynchronously
comment.notify_later(:users, key: 'comment.reply')
# Schedule cascade in a separate job or callback
class NotifyWithCascadeJob < ApplicationJob
def perform(notifiable_type, notifiable_id, target_type, cascade_config)
notifiable = notifiable_type.constantize.find(notifiable_id)
# Get the notifications created for this notifiable
notifications = ActivityNotification::Notification
.where(notifiable: notifiable)
.where(target_type: target_type.classify)
.unopened_only
# Apply cascade to each notification
notifications.each do |notification|
notification.cascade_notify(cascade_config)
end
end
end
# Usage
cascade_config = [
{ delay: 10.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
]
NotifyWithCascadeJob.perform_later(
'Comment',
comment.id,
'users',
cascade_config
)
```
## Validation
### Automatic Validation
By default, `cascade_notify` validates the configuration before scheduling jobs:
```ruby
# This will raise ArgumentError if config is invalid
notification.cascade_notify(invalid_config)
# => ArgumentError: Invalid cascade configuration: Step 0 missing required :target parameter
```
### Manual Validation
You can validate a configuration before using it:
```ruby
result = notification.validate_cascade_config(cascade_config)
if result[:valid]
notification.cascade_notify(cascade_config)
else
Rails.logger.error("Invalid cascade config: #{result[:errors].join(', ')}")
end
```
### Skipping Validation
For performance-critical scenarios where you're confident in your configuration:
```ruby
notification.cascade_notify(cascade_config, validate: false)
```
## Error Handling
### Graceful Error Recovery
The cascading notification system respects the global `rescue_optional_target_errors` configuration:
```ruby
# In config/initializers/activity_notification.rb
ActivityNotification.configure do |config|
config.rescue_optional_target_errors = true # Default
end
```
When enabled:
- Errors in optional targets are caught and logged
- The cascade continues to subsequent steps
- Error information is returned in the job result
When disabled:
- Errors propagate and halt the cascade
- Useful for debugging and development
### Example Error Handling
```ruby
# In your optional target
class CustomOptionalTarget < ActivityNotification::OptionalTarget::Base
def notify(notification, options = {})
raise StandardError, "API unavailable" if service_down?
# ... normal notification logic
end
end
# With rescue_optional_target_errors = true:
# - Error is logged
# - Returns { custom: # }
# - Next cascade step is still scheduled
# With rescue_optional_target_errors = false:
# - Error propagates
# - Job fails
# - Next cascade step is NOT scheduled
```
## Read Status Checking
The cascade automatically stops when a notification is read at any point:
```ruby
# Start cascade
notification.cascade_notify(cascade_config)
# User opens notification after 5 minutes
notification.open!
# Subsequent cascade steps will detect opened? == true and exit immediately
# No further optional targets will be triggered
```
## Performance Considerations
### Job Queue Configuration
Cascading notifications use the configured ActiveJob queue:
```ruby
# In config/initializers/activity_notification.rb
ActivityNotification.configure do |config|
config.active_job_queue = :notifications # or :default, :high_priority, etc.
end
```
For high-volume applications, consider using a dedicated queue:
```ruby
config.active_job_queue = :cascading_notifications
```
### Database Queries
Each cascade step performs:
1. One `SELECT` to find the notification
2. One check of the `opened_at` field
3. Optional queries for target and notifiable associations
For optimal performance:
- Ensure `notifications.id` is indexed (primary key)
- Ensure `notifications.opened_at` is indexed
- Consider using database connection pooling
### Memory Usage
Each scheduled job holds:
- Notification ID (Integer)
- Cascade configuration (Array of Hashes)
- Current step index (Integer)
Total memory footprint per job: ~1-2 KB depending on configuration size
## Limitations and Known Issues
### 1. No Built-in Cascade State Tracking
The current implementation doesn't maintain explicit state about active cascades. The `cascade_in_progress?` method returns `false` by default.
**Workaround**: If you need to track cascade state, consider:
- Adding a custom field to your notification model
- Using Redis to store cascade state
- Querying the job queue (adapter-specific)
### 2. Cascade Configuration Not Persisted
Cascade configurations are passed as job arguments and not stored in the database.
**Implication**: You cannot query or modify a running cascade. Once started, it will complete its configured steps or stop when the notification is read.
**Workaround**: Store cascade configuration in notification `parameters` if needed for auditing:
```ruby
notification.update(parameters: notification.parameters.merge(
cascade_config: cascade_config
))
notification.cascade_notify(cascade_config)
```
### 3. Time Drift
Scheduled jobs may execute slightly later than the configured delay due to queue processing time.
**Mitigation**: The system uses `set(wait: delay)` which is accurate to within seconds for most ActiveJob adapters.
### 4. Deleted Notifications
If a notification is deleted while cascade jobs are scheduled, subsequent jobs will gracefully exit with `nil` return value.
### 5. Optional Target Availability
Cascades assume optional targets are configured on the notifiable model. If a target is removed from configuration after cascade starts, the job will return `:not_configured` status.
## Testing
### Unit Testing
```ruby
RSpec.describe "Cascading Notifications" do
it "schedules cascade jobs" do
notification = create(:notification)
cascade_config = [
{ delay: 10.minutes, target: :slack }
]
expect {
notification.cascade_notify(cascade_config)
}.to have_enqueued_job(ActivityNotification::CascadingNotificationJob)
end
end
```
### Integration Testing
```ruby
RSpec.describe "Cascading Notifications Integration" do
it "executes full cascade when unread" do
notification = create(:notification)
# Configure and start cascade
cascade_config = [
{ delay: 10.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
]
notification.cascade_notify(cascade_config)
# Simulate time passing
travel_to(10.minutes.from_now) do
# Perform first job
ActiveJob::Base.queue_adapter.enqueued_jobs.first[:job].constantize.perform_now(...)
# Verify second job was scheduled
expect(ActiveJob::Base.queue_adapter.enqueued_jobs.size).to eq(1)
end
end
end
```
### Testing with Time Travel
Use `travel_to` or `Timecop` to test time-delayed behavior:
```ruby
it "stops cascade when notification is read" do
notification = create(:notification)
cascade_config = [
{ delay: 5.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
]
notification.cascade_notify(cascade_config)
# First step executes
travel_to(5.minutes.from_now) do
perform_enqueued_jobs
end
# User reads notification
notification.open!
# Second step should exit without triggering
travel_to(15.minutes.from_now) do
job_instance = CascadingNotificationJob.new
result = job_instance.perform(notification.id, cascade_config, 1)
expect(result).to be_nil
end
end
```
## Migration Guide
### For Existing Applications
1. **Update notification models**: No changes needed - the API is automatically included
2. **Configure optional targets**: Ensure your notifiable models have optional targets configured
3. **Add cascade configurations**: Define cascade configs where needed
4. **Test thoroughly**: Use the test suite to verify cascade behavior
5. **Monitor job queue**: Watch for job buildup or delays in processing
### Example Migration
**Before** (manual escalation):
```ruby
# Controller
comment.notify(:users)
# Separate delayed job for escalation
EscalationJob.set(wait: 10.minutes).perform_later(comment.id)
```
**After** (cascading notifications):
```ruby
# Controller
comment.notify(:users)
# Start cascade immediately
comment.notifications.each do |notification|
notification.cascade_notify([
{ delay: 10.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
])
end
```
## Best Practices
### 1. Choose Appropriate Delays
- **Too short**: May annoy users with rapid escalation
- **Too long**: Users may miss important notifications
- **Recommended**: Start with 10-15 minute intervals, adjust based on user behavior
### 2. Limit Cascade Depth
- Keep cascades to 3-4 steps maximum
- Each additional step increases job queue load
- Consider user experience - excessive notifications are counterproductive
### 3. Use Specific Optional Target Options
```ruby
# Good: Specific, actionable messages
{
delay: 10.minutes,
target: :slack,
options: {
channel: '#urgent-alerts',
message: 'You have an unread notification requiring attention'
}
}
# Avoid: Generic messages without context
{ delay: 10.minutes, target: :slack }
```
### 4. Handle Subscription Status
Respect user preferences by ensuring optional targets check subscription:
```ruby
# In your optional target
def notify(notification, options = {})
return unless notification.optional_target_subscribed?(:slack)
# ... notification logic
end
```
### 5. Monitor and Alert
Set up monitoring for:
- Cascade job success/failure rates
- Average time between cascade steps
- Percentage of cascades that complete vs. stop early
- User engagement after cascade notifications
### 6. Document Your Cascade Strategies
```ruby
# Good: Clear documentation of strategy
# Urgent notifications: Escalate quickly through Slack → SMS → Phone
# Regular notifications: Gentle escalation through in-app → Email
URGENT_CASCADE = [
{ delay: 2.minutes, target: :slack, options: { channel: '#urgent' } },
{ delay: 5.minutes, target: :sms },
{ delay: 10.minutes, target: :phone }
].freeze
REGULAR_CASCADE = [
{ delay: 30.minutes, target: :email }
].freeze
```
## Architecture Decisions
### Why ActiveJob?
- **Standard Rails integration**: Works with any ActiveJob adapter
- **Persistence**: Job state is maintained by the adapter
- **Retries**: Built-in retry mechanisms for failed jobs
- **Monitoring**: Compatible with job monitoring tools
### Why Not Use Scheduled Jobs?
The cascade could have been implemented with cron-like scheduled jobs that periodically check for unread notifications. However:
- **Scalability**: Per-notification jobs scale better than scanning all notifications
- **Precision**: Exact delays per notification rather than polling intervals
- **Resource usage**: Only creates jobs for cascading notifications, not all notifications
### Why Pass Configuration as Job Arguments?
Cascade configuration is passed to jobs rather than stored in the database because:
- **Simplicity**: No schema changes required
- **Flexibility**: Configuration can be programmatically generated
- **Immutability**: Cascade behavior is fixed once started (predictable)
Trade-off: Cannot modify running cascades (acceptable for most use cases)
### Why Check Read Status in Job?
The job checks `notification.opened?` rather than relying on cancellation because:
- **Reliability**: Cancelling jobs is adapter-specific and not universally supported
- **Simplicity**: Single query is cheaper than job cancellation logic
- **Race conditions**: Avoids race between reading notification and cancelling jobs
## Future Enhancements
Potential improvements for future versions:
1. **Cascade Templates**: Pre-defined cascade strategies
2. **Dynamic Delays**: Calculate delays based on notification priority or time of day
3. **Cascade Analytics**: Built-in tracking of cascade effectiveness
4. **Cascade Cancellation**: Explicit API to cancel running cascades
5. **Batch Cascading**: Apply cascades to multiple notifications efficiently
6. **Cascade State Tracking**: Persist cascade state in database or Redis
7. **Custom Conditions**: Beyond read status (e.g., user online status)
8. **Cascade Hooks**: Callbacks for cascade start, step, complete events
## Troubleshooting
### Cascade Not Starting
**Symptom**: Calling `cascade_notify` returns `false`
**Possible causes**:
1. Notification already opened: Check `notification.opened?`
2. Empty cascade config: Verify config is not `[]`
3. ActiveJob not available: Check Rails environment
4. Validation failing: Try with `validate: false` to see if config is invalid
### Jobs Not Executing
**Symptom**: Jobs scheduled but not running
**Check**:
1. ActiveJob adapter is running (e.g., Sidekiq, Delayed Job)
2. Queue name matches: `ActivityNotification.config.active_job_queue`
3. Job is in correct queue: Inspect `ActiveJob::Base.queue_adapter`
### Cascade Not Stopping When Read
**Symptom**: Notifications keep sending after user reads
**Check**:
1. `notification.open!` is being called correctly
2. `opened_at` field is being set in database
3. Job is checking the correct notification ID
4. Database transactions are committing properly
### Optional Target Not Triggered
**Symptom**: Jobs execute but target not notified
**Check**:
1. Optional target is configured on notifiable model
2. Target name matches exactly (`:slack` vs `'slack'`)
3. Subscription status: `notification.optional_target_subscribed?(target_name)`
4. Optional target's `notify` method is implemented correctly
## Support and Contributing
For issues, questions, or contributions related to cascading notifications:
1. Check existing GitHub issues

# Cascading Notifications - Quick Start Guide
## What Are Cascading Notifications?
Cascading notifications allow you to automatically send notifications through multiple channels (Slack, Email, SMS, etc.) with time delays, but only if the user hasn't already read the notification.
**Example Flow:**
1. User gets an in-app notification
2. ⏱️ Wait 10 minutes → Still unread? Send Slack message
3. ⏱️ Wait 10 more minutes → Still unread? Send Email
4. ⏱️ Wait 30 more minutes → Still unread? Send SMS
If the user reads the notification at any point, the cascade stops automatically!
## Quick Examples
### Example 1: Simple Two-Step Cascade
```ruby
# Create a notification
notification = Notification.create!(
target: user,
notifiable: comment,
key: 'comment.reply'
)
# Setup cascade: Slack after 10 min, Email after another 10 min
cascade_config = [
{ delay: 10.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
]
# Start the cascade
notification.cascade_notify(cascade_config)
```
### Example 2: Immediate First Notification
```ruby
# Send Slack immediately, then email if still unread
cascade_config = [
{ delay: 5.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
]
notification.cascade_notify(cascade_config, trigger_first_immediately: true)
```
### Example 3: With Custom Options
```ruby
cascade_config = [
{
delay: 5.minutes,
target: :slack,
options: { channel: '#urgent' }
},
{
delay: 10.minutes,
target: :email
}
]
notification.cascade_notify(cascade_config)
```
### Example 4: Integration with Notification Creation
```ruby
# In your controller
comment = Comment.create!(comment_params)
# Create notifications
comment.notify(:users, key: 'comment.new')
# Add cascade to all created notifications
comment.notifications.each do |notification|
cascade_config = [
{ delay: 10.minutes, target: :slack },
{ delay: 30.minutes, target: :email }
]
notification.cascade_notify(cascade_config)
end
```
## Configuration Format
Each step in the cascade requires:
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `delay` | Duration | Yes | How long to wait (e.g., `10.minutes`, `1.hour`) |
| `target` | Symbol/String | Yes | Optional target name (`:slack`, `:email`, etc.) |
| `options` | Hash | No | Custom options to pass to the target |
## Common Patterns
### Urgent Notifications (Fast Escalation)
```ruby
URGENT_CASCADE = [
{ delay: 2.minutes, target: :slack },
{ delay: 5.minutes, target: :email },
{ delay: 10.minutes, target: :sms }
].freeze
```
### Normal Notifications (Gentle Escalation)
```ruby
NORMAL_CASCADE = [
{ delay: 30.minutes, target: :slack },
{ delay: 1.hour, target: :email }
].freeze
```
### Reminder Pattern (Long Delays)
```ruby
REMINDER_CASCADE = [
{ delay: 1.day, target: :email },
{ delay: 3.days, target: :email },
{ delay: 1.week, target: :email }
].freeze
```
## Prerequisites
Before using cascading notifications, make sure:
1. **Optional targets are configured** on your notifiable models
2. **ActiveJob is configured** (default in Rails)
3. **Job queue is running** (Sidekiq, Delayed Job, etc.)
Example optional target configuration:
```ruby
class Comment < ApplicationRecord
require 'activity_notification/optional_targets/slack'
acts_as_notifiable :users,
targets: ->(comment, key) { ... },
optional_targets: {
ActivityNotification::OptionalTarget::Slack => {
webhook_url: ENV['SLACK_WEBHOOK_URL'],
channel: '#notifications'
}
}
end
```
## Testing
### Basic Test
```ruby
it "schedules cascade jobs" do
notification = create(:notification)
cascade_config = [
{ delay: 10.minutes, target: :slack }
]
expect {
notification.cascade_notify(cascade_config)
}.to have_enqueued_job(ActivityNotification::CascadingNotificationJob)
end
```
### Testing with Time Travel
```ruby
it "stops cascade when notification is read" do
notification = create(:notification)
cascade_config = [
{ delay: 10.minutes, target: :slack },
{ delay: 10.minutes, target: :email }
]
notification.cascade_notify(cascade_config)
# Mark as read before second step
travel_to(15.minutes.from_now) do
notification.open!
# Execute job - should exit without sending
job = CascadingNotificationJob.new
result = job.perform(notification.id, cascade_config, 1)
expect(result).to be_nil
end
end
```
## Validation
Cascade configurations are automatically validated:
```ruby
# Valid
notification.cascade_notify([
{ delay: 10.minutes, target: :slack }
])
# Invalid - will raise ArgumentError
notification.cascade_notify([
{ target: :slack } # Missing delay
])
# => ArgumentError: Invalid cascade configuration: Step 0 missing :delay parameter
# Skip validation (not recommended)
notification.cascade_notify(config, validate: false)
```
## Troubleshooting
### Cascade Not Starting
Check:
- Is notification already opened? `notification.opened?`
- Is config valid? `notification.validate_cascade_config(config)`
- Is ActiveJob running?
### Jobs Not Executing
Check:
- Job queue is running (Sidekiq, Delayed Job, etc.)
- Correct queue name: `ActivityNotification.config.active_job_queue`
- Jobs in queue: `ActiveJob::Base.queue_adapter.enqueued_jobs`
### Target Not Triggered
Check:
- Optional target is configured on notifiable model
- Target name matches (`:slack` not `'Slack'`)
- User is subscribed: `notification.optional_target_subscribed?(:slack)`
## Options Reference
### cascade_notify Options
```ruby
notification.cascade_notify(cascade_config, options)
```
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `validate` | Boolean | `true` | Validate config before starting |
| `trigger_first_immediately` | Boolean | `false` | Trigger first target without delay |
## Best Practices
### ✅ DO
- Keep cascades to 3-4 steps maximum
- Use meaningful delays (10-30 minutes for urgent, 1+ hours for normal)
- Document your cascade strategies
- Test cascade behavior with time travel
- Respect user subscription preferences
### ❌ DON'T
- Create cascades with too many steps
- Use very short delays (< 2 minutes) for non-urgent notifications
- Skip validation in production
- Forget to configure optional targets
- Ignore error handling
## API Reference
### Main Methods
#### `cascade_notify(cascade_config, options = {})`
Starts a cascading notification sequence.
**Returns:** `true` if cascade started, `false` otherwise
#### `validate_cascade_config(cascade_config)`
Validates a cascade configuration.
**Returns:** Hash with `:valid` (Boolean) and `:errors` (Array) keys
#### `cascade_in_progress?`
Checks if a cascade is currently running (always returns `false` in current implementation).
**Returns:** Boolean
## Summary
Cascading notifications make it easy to ensure important notifications are seen without being intrusive. Start with simple two-step cascades and adjust based on user behavior and feedback.
**Remember:** The cascade automatically stops when the user reads the notification, so you're never sending unnecessary notifications! 🎉

# Design Document for NotificationApi Performance Optimization
## Architecture Overview
The performance optimization introduces two key methods to the NotificationApi module to address memory efficiency issues when processing large target collections:
1. **`targets_empty?`** - Optimized empty collection checking
2. **`process_targets_in_batches`** - Batch processing for large collections
## Design Principles
### Principle 1: Minimal API Impact
The optimization maintains full backward compatibility by:
- Preserving all existing method signatures
- Maintaining consistent return value types
- Adding internal helper methods without changing public interface
### Principle 2: Progressive Enhancement
The implementation uses capability detection to apply optimizations:
- ActiveRecord relations → Use `exists?` and `find_each`
- Mongoid criteria → Use cursor-based iteration
- Arrays → Use existing `map` processing (already in memory)
### Principle 3: Configurable Performance
Users can tune performance through options:
- `batch_size` option for custom batch sizes
- Automatic fallback for unsupported collection types
## Detailed Design
### Component 1: Empty Collection Check Optimization
#### Current Implementation Problem
```ruby
# BEFORE: Loads all records into memory
return if targets.blank? # Executes SELECT * FROM users
```
#### Optimized Implementation
```ruby
def targets_empty?(targets)
if targets.respond_to?(:exists?)
!targets.exists? # Executes SELECT 1 FROM users LIMIT 1
else
targets.blank? # Fallback for arrays
end
end
```
#### Design Rationale
- **Database Efficiency**: `exists?` generates `SELECT 1 ... LIMIT 1` instead of loading all records
- **Type Safety**: Uses duck typing to detect ActiveRecord/Mongoid relations
- **Backward Compatibility**: Falls back to `blank?` for arrays and other types
### Component 2: Batch Processing Implementation
#### Current Implementation Problem
```ruby
# BEFORE: Loads all records into memory at once
targets.map { |target| notify_to(target, notifiable, options) }
```
#### Optimized Implementation
```ruby
def process_targets_in_batches(targets, notifiable, options = {})
notifications = []
if targets.respond_to?(:find_each)
# ActiveRecord: Use find_each for batching
batch_options = {}
batch_options[:batch_size] = options[:batch_size] if options[:batch_size]
targets.find_each(**batch_options) do |target|
notification = notify_to(target, notifiable, options)
notifications << notification
end
elsif defined?(Mongoid::Criteria) && targets.is_a?(Mongoid::Criteria)
# Mongoid: Use cursor-based iteration
targets.each do |target|
notification = notify_to(target, notifiable, options)
notifications << notification
end
else
# Arrays: Use standard map (already in memory)
notifications = targets.map { |target| notify_to(target, notifiable, options) }
end
notifications
end
```
#### Design Rationale
- **Memory Efficiency**: `find_each` processes records in batches (default 1000)
- **Framework Support**: Handles ActiveRecord, Mongoid, and arrays appropriately
- **Configurability**: Supports custom `batch_size` option
- **Consistency**: Returns same Array format as original implementation
## Integration Points
### Modified Methods
#### `notify` Method Integration
```ruby
def notify(targets, notifiable, options = {})
# Use optimized empty check
return if targets_empty?(targets)
# Existing logic continues unchanged...
notify_all(targets, notifiable, options)
end
```
#### `notify_all` Method Integration
```ruby
def notify_all(targets, notifiable, options = {})
# Use optimized batch processing
process_targets_in_batches(targets, notifiable, options)
end
```
## Performance Characteristics
### Memory Usage Patterns
#### Before Optimization
```
Memory Usage = O(n) where n = number of records
- Empty check: Loads all n records
- Processing: Loads all n records simultaneously
- Peak memory: 2n records in memory
```
#### After Optimization
```
Memory Usage = O(batch_size) where batch_size = 1000 (default)
- Empty check: Loads 0 records (uses EXISTS query)
- Processing: Loads batch_size records at a time
- Peak memory: batch_size records in memory
```
### Query Patterns
#### Before Optimization
```sql
-- Empty check
SELECT * FROM users WHERE ...; -- Loads all records
-- Processing
SELECT * FROM users WHERE ...; -- Loads all records again
-- Then N INSERT queries for notifications
```
#### After Optimization
```sql
-- Empty check
SELECT 1 FROM users WHERE ... LIMIT 1; -- Existence check only
-- Processing
SELECT * FROM users WHERE ... LIMIT 1000 OFFSET 0; -- Batch 1
SELECT * FROM users WHERE ... LIMIT 1000 OFFSET 1000; -- Batch 2
-- Continue in batches...
-- N INSERT queries for notifications (unchanged)
```
## Error Handling and Edge Cases
### Edge Case 1: Empty Collections
- **Input**: Empty ActiveRecord relation
- **Behavior**: `targets_empty?` returns `true`, processing skipped
- **Queries**: 1 EXISTS query only
### Edge Case 2: Single Record Collections
- **Input**: Relation with 1 record
- **Behavior**: `find_each` processes single batch
- **Queries**: 1 SELECT + 1 INSERT
### Edge Case 3: Large Collections
- **Input**: 10,000+ records
- **Behavior**: Processed in batches of 1000 (configurable)
- **Memory**: Constant regardless of total size
### Edge Case 4: Mixed Collection Types
- **Input**: Array of User objects
- **Behavior**: Falls back to standard `map` processing
- **Rationale**: Arrays are already in memory
## Correctness Properties
### Property 1: Functional Equivalence
**Invariant**: For any input, the optimized implementation produces identical results to the original implementation.
**Verification**:
- Same notification objects created
- Same notification attributes
- Same return value structure (Array)
### Property 2: Performance Improvement
**Invariant**: Memory usage remains bounded regardless of input size.
**Verification**:
- Memory increase < 50MB for 1000 records
- Query count < 100 for 1000 records
- Processing time scales linearly, not exponentially
### Property 3: Backward Compatibility
**Invariant**: All existing code continues to work without modification.
**Verification**:
- Method signatures unchanged
- Return types unchanged
- Options hash backward compatible
## Testing Strategy
### Unit Tests
- Test each helper method in isolation
- Mock external dependencies (ActiveRecord, Mongoid)
- Verify correct method calls and parameters
### Integration Tests
- Test complete workflow with real database
- Verify notification creation and attributes
- Test with various collection types and sizes
### Performance Tests
- Measure memory usage with system-level RSS
- Count database queries using ActiveSupport::Notifications
- Compare optimized vs unoptimized approaches
- Validate performance targets
### Regression Tests
- Run existing test suite to ensure no breaking changes
- Test backward compatibility with various input types
- Verify edge cases and error conditions
## Configuration Options
### Batch Size Configuration
```ruby
# Default batch size (1000)
notify_all(users, comment)
# Custom batch size
notify_all(users, comment, batch_size: 500)
# Large batch size for high-memory environments
notify_all(users, comment, batch_size: 5000)
```
### Framework Detection
The implementation automatically detects and adapts to:
- **ActiveRecord**: Uses `respond_to?(:find_each)` and `respond_to?(:exists?)`
- **Mongoid**: Uses `defined?(Mongoid::Criteria)` and type checking
- **Arrays**: Falls back when other conditions not met
## Monitoring and Observability
### Performance Metrics
The implementation can be monitored through:
- **Memory Usage**: System RSS before/after processing
- **Query Count**: ActiveSupport::Notifications SQL events
- **Processing Time**: Duration of batch processing operations
- **Throughput**: Notifications created per second
### Logging Integration
```ruby
# Example logging integration (not implemented)
Rails.logger.info "Processing #{targets.count} targets in batches"
Rails.logger.info "Batch processing completed: #{notifications.size} notifications created"
```
## Future Enhancements
### Potential Improvements
1. **Streaming Results**: Option to yield notifications instead of accumulating array
2. **Batch Insertion**: Use `insert_all` for bulk notification creation
3. **Progress Callbacks**: Yield progress information during batch processing
4. **Async Processing**: Background job integration for very large collections
### API Evolution
```ruby
# Potential future API (not implemented)
notify_all(users, comment, stream_results: true) do |notification|
# Process each notification as it's created
end
```
## Security Considerations
### SQL Injection Prevention
- Uses ActiveRecord's built-in query methods (`exists?`, `find_each`)
- No raw SQL construction
- Parameterized queries maintained
### Memory Exhaustion Prevention
- Bounded memory usage through batching
- Configurable batch sizes for resource management
- Graceful handling of large collections
## Deployment Considerations
### Rolling Deployment Safety
- Backward compatible changes only
- No database migrations required
- Can be deployed incrementally
### Performance Impact
- Immediate memory usage improvements
- Potential slight increase in query count (batching)
- Overall performance improvement for large collections
### Monitoring Requirements
- Monitor memory usage patterns post-deployment
- Track query performance and patterns
- Validate performance improvements in production

# Requirements for NotificationApi Performance Optimization
## Problem Statement
GitHub Issue #148 reports significant memory consumption issues when processing large target collections in the NotificationApi. The current implementation loads entire collections into memory for basic operations, causing performance degradation and potential out-of-memory errors.
## Functional Requirements
### FR-1: Empty Collection Check Optimization
**EARS Format**: The system SHALL use database-level existence checks instead of loading all records when determining if a target collection is empty.
**Acceptance Criteria**:
- When `targets.blank?` is called on ActiveRecord relations, the system SHALL use `targets.exists?` instead
- The system SHALL execute at most 1 SELECT query for empty collection checks
- The system SHALL maintain backward compatibility with array inputs using `blank?`
### FR-2: Batch Processing for Large Collections
**EARS Format**: The system SHALL process large target collections in configurable batches to minimize memory consumption.
**Acceptance Criteria**:
- When processing ActiveRecord relations, the system SHALL use `find_each` with default batch size of 1000
- The system SHALL support custom `batch_size` option for fine-tuning
- The system SHALL process Mongoid criteria using cursor-based iteration
- The system SHALL fall back to standard `map` processing for arrays (already in memory)
### FR-3: Memory Efficiency
**EARS Format**: The system SHALL maintain memory consumption within acceptable bounds regardless of target collection size.
**Acceptance Criteria**:
- Memory increase SHALL be less than 50MB when processing 1000 records
- Batch processing memory usage SHALL not exceed 1.5x the optimized approach
- The system SHALL demonstrate linear memory scaling prevention through batching
### FR-4: Backward Compatibility
**EARS Format**: The system SHALL maintain full backward compatibility with existing API usage patterns.
**Acceptance Criteria**:
- All existing method signatures SHALL remain unchanged
- Return value types SHALL remain consistent (Array of notifications)
- Existing functionality SHALL work without modification
- No breaking changes SHALL be introduced
## Non-Functional Requirements
### NFR-1: Performance Targets
Based on the optimization goals, the system SHALL achieve:
- **10K records**: 90% memory reduction (100MB → 10MB)
- **100K records**: 99% memory reduction (1GB → 10MB)
- **1M records**: 99.9% memory reduction (10GB → 10MB)
### NFR-2: Query Efficiency
- Empty collection checks SHALL execute ≤1 database query
- Batch processing SHALL use <100 queries for 1000 records (preventing N+1)
- Query count SHALL not scale linearly with record count
### NFR-3: Maintainability
- Code changes SHALL be minimal and focused
- New methods SHALL follow existing naming conventions
- Implementation SHALL be testable and well-documented
## Technical Constraints
### TC-1: Framework Compatibility
- The system SHALL support ActiveRecord relations
- The system SHALL support Mongoid criteria (when available)
- The system SHALL support plain Ruby arrays
- The system SHALL work across Rails versions 5.0-8.0
### TC-2: API Stability
- Method signatures SHALL remain unchanged
- Return value formats SHALL remain consistent
- Options hash SHALL be backward compatible
## Success Criteria
The implementation SHALL be considered successful when:
1. **Performance Tests Pass**: All automated performance tests demonstrate expected improvements
2. **Memory Targets Met**: Actual memory usage meets or exceeds the specified reduction targets
3. **No Regressions**: Existing functionality continues to work without modification
4. **Query Optimization Verified**: Database query patterns show batching instead of N+1 behavior
5. **Documentation Complete**: Implementation is properly documented and testable
## Out of Scope
The following items are explicitly out of scope for this optimization:
- Changes to notification creation logic or callbacks
- Modifications to email sending or background job processing
- Database schema changes
- Changes to the public API surface
- Performance optimizations for notification retrieval or querying
## Risk Assessment
### High Risk
- **Memory measurement accuracy**: System-level RSS measurement can vary, requiring robust test thresholds
- **Query counting reliability**: ActiveRecord query counting may vary across versions
### Medium Risk
- **Batch size tuning**: Default batch size may need adjustment based on real-world usage
- **Framework compatibility**: Behavior differences across Rails/ORM versions
### Low Risk
- **Backward compatibility**: Minimal API changes reduce compatibility risk
- **Test coverage**: Comprehensive test suite reduces implementation risk
## Dependencies
- ActiveRecord (for `exists?` and `find_each` methods)
- Mongoid (optional, for Mongoid criteria support)
- RSpec (for performance testing framework)
- FactoryBot (for test data generation)
## Acceptance Testing Strategy
Performance improvements SHALL be validated through:
1. **Automated Performance Tests**: Comprehensive test suite measuring memory usage, query efficiency, and processing time
2. **Memory Profiling**: System-level RSS measurement during batch processing
3. **Query Analysis**: ActiveSupport::Notifications tracking of database queries
4. **Regression Testing**: Existing test suite validation
5. **Integration Testing**: End-to-end workflow validation with large datasets

# Design: Email Attachments Support (#154)
## Overview
Follows the same pattern as the CC feature (#107). Three-level configuration, no database changes, integrates into existing mailer helpers.
## Attachment Specification Format
```ruby
{
filename: String, # Required
content: String/Binary, # Either :content or :path required
path: String, # Either :content or :path required
mime_type: String # Optional, inferred from filename if omitted
}
```
## Configuration Levels
### 1. Global (`config.mailer_attachments`)
```ruby
# Single attachment
config.mailer_attachments = { filename: 'terms.pdf', path: Rails.root.join('public', 'terms.pdf') }
# Multiple attachments
config.mailer_attachments = [
{ filename: 'logo.png', path: Rails.root.join('app/assets/images/logo.png') },
{ filename: 'terms.pdf', content: generate_pdf }
]
# Dynamic (Proc receives notification key)
config.mailer_attachments = ->(key) {
key.include?('invoice') ? { filename: 'invoice.pdf', content: generate_invoice } : nil
}
```
### 2. Target (`target.mailer_attachments`)
```ruby
class User < ActiveRecord::Base
acts_as_target email: :email
def mailer_attachments
admin? ? { filename: 'admin_guide.pdf', path: '/path/to/guide.pdf' } : nil
end
end
```
### 3. Notifiable Override (`notifiable.overriding_notification_email_attachments`)
```ruby
class Invoice < ActiveRecord::Base
acts_as_notifiable :users, targets: -> { ... }
def overriding_notification_email_attachments(target, key)
{ filename: "invoice_#{id}.pdf", content: generate_pdf }
end
end
```
## Implementation
### config.rb
Add `mailer_attachments` attribute, initialize to `nil`.
### mailers/helpers.rb
#### New method: `mailer_attachments(target)`
Same pattern as `mailer_cc(target)`:
```ruby
def mailer_attachments(target)
if target.respond_to?(:mailer_attachments)
target.mailer_attachments
elsif ActivityNotification.config.mailer_attachments.present?
if ActivityNotification.config.mailer_attachments.is_a?(Proc)
key = @notification ? @notification.key : nil
ActivityNotification.config.mailer_attachments.call(key)
else
ActivityNotification.config.mailer_attachments
end
else
nil
end
end
```
#### New method: `resolve_attachments(key)`
Resolve with notifiable override priority:
```ruby
def resolve_attachments(key)
if @notification&.notifiable&.respond_to?(:overriding_notification_email_attachments) &&
@notification.notifiable.overriding_notification_email_attachments(@target, key).present?
@notification.notifiable.overriding_notification_email_attachments(@target, key)
else
mailer_attachments(@target)
end
end
```
#### New method: `process_attachments(mail_obj, specs)`
```ruby
def process_attachments(mail_obj, specs)
return if specs.blank?
Array(specs).each do |spec|
next if spec.blank?
validate_attachment_spec!(spec)
content = spec[:content] || File.read(spec[:path])
options = { content: content }
options[:mime_type] = spec[:mime_type] if spec[:mime_type]
mail_obj.attachments[spec[:filename]] = options
end
end
```
#### Modified: `headers_for`
Add attachment resolution, store in headers:
```ruby
attachment_specs = resolve_attachments(key)
headers[:attachment_specs] = attachment_specs if attachment_specs.present?
```
#### Modified: `send_mail`
Extract and process attachments:
```ruby
def send_mail(headers, fallback = nil)
attachment_specs = headers.delete(:attachment_specs)
begin
mail_obj = mail headers
process_attachments(mail_obj, attachment_specs)
mail_obj
rescue ActionView::MissingTemplate => e
if fallback.present?
mail_obj = mail headers.merge(template_name: fallback)
process_attachments(mail_obj, attachment_specs)
mail_obj
else
raise e
end
end
end
```
### Generator Template
Add commented configuration example to `activity_notification.rb` template.

# Requirements: Email Attachments Support (#154)
## Overview
Add support for email attachments to notification emails. Currently, users must override the mailer to add attachments. This feature provides a clean API following the same pattern as the existing CC feature (#107).
## Requirements
### R1: Global Attachment Configuration
As a developer, I want to configure default attachments for all notification emails at the gem level.
1. `config.mailer_attachments` in the initializer applies attachments to all notification emails
2. Supports Hash (single), Array of Hash (multiple), Proc (dynamic), or nil (none)
3. When Proc, called with notification key as parameter
4. When nil or empty, no attachments added
### R2: Target-Level Attachment Configuration
As a developer, I want to define attachments at the target model level.
1. When target defines `mailer_attachments` method, those attachments are used
2. Returns Array of attachment specs, single Hash, or nil
3. When nil, falls back to global configuration
### R3: Notifiable-Level Attachment Override
As a developer, I want to override attachments per notification type in the notifiable model.
1. When notifiable defines `overriding_notification_email_attachments(target, key)`, used with highest priority
2. Receives target and notification key as parameters
3. When nil, falls back to target-level or global configuration
### R4: Attachment Resolution Priority
1. Priority order: notifiable override > target method > global configuration
2. When higher-priority returns nil, fall back to next level
3. When all return nil, send email without attachments
### R5: Attachment Format
1. Hash with `:filename` (required) and `:content` (binary data)
2. Hash with `:filename` (required) and `:path` (local file path)
3. Optional `:mime_type` key; inferred from filename if not provided
4. Exactly one of `:content` or `:path` must be provided
5. Multiple attachments as Array of Hashes
### R6: Error Handling
1. Missing `:filename` raises ArgumentError
2. Missing both `:content` and `:path` raises ArgumentError
3. Non-existent file path raises ArgumentError
4. Non-Hash spec raises ArgumentError
### R7: Backward Compatibility
1. No attachments when `mailer_attachments` is not configured
2. No database migrations required
3. Existing mailer customizations continue to work
### R8: Batch Notification Attachments
1. Batch notification emails support attachments using the same configuration
2. Same resolution priority applies

# Design Document: Bulk destroy notifications API
## Issue Summary
GitHub Issue [#172](https://github.com/simukappu/activity_notification/issues/172) requests the ability to delete more than one notification for a target. Currently, only single notification deletion is available through the `destroy` API. The user wants a `bulk_destroy` API or provision to create custom APIs for bulk destroying notifications.
## Current State Analysis
### Existing Destroy Functionality
- **Single Destroy**: `DELETE /:target_type/:target_id/notifications/:id`
- Implemented in `NotificationsController#destroy`
- API version in `NotificationsApiController#destroy`
- Simply calls `@notification.destroy` on individual notification
### Existing Bulk Operations Pattern
- **Bulk Open**: `POST /:target_type/:target_id/notifications/open_all`
- Implemented in `NotificationsController#open_all`
- Uses `@target.open_all_notifications(params)`
- Backend implementation in `NotificationApi#open_all_of`
- Uses `update_all(opened_at: opened_at)` for efficient bulk updates
## Proposed Implementation
### 1. Backend API Method (NotificationApi)
**File**: `lib/activity_notification/apis/notification_api.rb`
Add a new class method `destroy_all_of` following the pattern of `open_all_of`:
```ruby
# Destroys all notifications of the target matching the filter criteria.
#
# @param [Object] target Target of the notifications to destroy
# @param [Hash] options Options for filtering notifications to destroy
# @option options [String] :filtered_by_type (nil) Notifiable type for filter
# @option options [Object] :filtered_by_group (nil) Group instance for filter
# @option options [String] :filtered_by_group_type (nil) Group type for filter, valid with :filtered_by_group_id
# @option options [String] :filtered_by_group_id (nil) Group instance id for filter, valid with :filtered_by_group_type
# @option options [String] :filtered_by_key (nil) Key of the notification for filter
# @option options [String] :later_than (nil) ISO 8601 format time to filter notifications later than specified time
# @option options [String] :earlier_than (nil) ISO 8601 format time to filter notifications earlier than specified time
# @option options [Array] :ids (nil) Array of specific notification IDs to destroy
# @return [Array] Destroyed notification records
def destroy_all_of(target, options = {})
```
### 2. Target Model Method
**File**: `lib/activity_notification/models/concerns/target.rb`
Add instance method `destroy_all_notifications` following the pattern of `open_all_notifications`:
```ruby
# Destroys all notifications of the target matching the filter criteria.
#
# @param [Hash] options Options for filtering notifications to destroy
# @option options [String] :filtered_by_type (nil) Notifiable type for filter
# @option options [Object] :filtered_by_group (nil) Group instance for filter
# @option options [String] :filtered_by_group_type (nil) Group type for filter, valid with :filtered_by_group_id
# @option options [String] :filtered_by_group_id (nil) Group instance id for filter, valid with :filtered_by_group_type
# @option options [String] :filtered_by_key (nil) Key of the notification for filter
# @option options [String] :later_than (nil) ISO 8601 format time to filter notifications later than specified time
# @option options [String] :earlier_than (nil) ISO 8601 format time to filter notifications earlier than specified time
# @option options [Array] :ids (nil) Array of specific notification IDs to destroy
# @return [Array] Destroyed notification records
def destroy_all_notifications(options = {})
```
### 3. Controller Actions
#### Web Controller
**File**: `app/controllers/activity_notification/notifications_controller.rb`
Add new action `destroy_all`:
```ruby
# Destroys all notifications of the target matching filter criteria.
#
# POST /:target_type/:target_id/notifications/destroy_all
# @overload destroy_all(params)
# @param [Hash] params Request parameters
# @option params [String] :filter (nil) Filter option to load notification index by their status (Nothing as auto, 'opened' or 'unopened')
# @option params [String] :limit (nil) Maximum number of notifications to return
# @option params [String] :without_grouping ('false') Whether notification index will include group members
# @option params [String] :with_group_members ('false') Whether notification index will include group members
# @option params [String] :filtered_by_type (nil) Notifiable type to filter notifications
# @option params [String] :filtered_by_group_type (nil) Group type to filter notifications, valid with :filtered_by_group_id
# @option params [String] :filtered_by_group_id (nil) Group instance ID to filter notifications, valid with :filtered_by_group_type
# @option params [String] :filtered_by_key (nil) Key of notifications to filter
# @option params [String] :later_than (nil) ISO 8601 format time to filter notifications later than specified time
# @option params [String] :earlier_than (nil) ISO 8601 format time to filter notifications earlier than specified time
# @option params [Array] :ids (nil) Array of specific notification IDs to destroy
# @option params [String] :reload ('true') Whether notification index will be reloaded
# @return [Response] JavaScript view for ajax request or redirects to back as default
def destroy_all
```
#### API Controller
**File**: `app/controllers/activity_notification/notifications_api_controller.rb`
Add new action `destroy_all`:
```ruby
# Destroys all notifications of the target matching filter criteria.
#
# POST /:target_type/:target_id/notifications/destroy_all
# @overload destroy_all(params)
# @param [Hash] params Request parameters
# @option params [String] :filtered_by_type (nil) Notifiable type to filter notifications
# @option params [String] :filtered_by_group_type (nil) Group type to filter notifications, valid with :filtered_by_group_id
# @option params [String] :filtered_by_group_id (nil) Group instance ID to filter notifications, valid with :filtered_by_group_type
# @option params [String] :filtered_by_key (nil) Key of notifications to filter
# @option params [String] :later_than (nil) ISO 8601 format time to filter notifications later than specified time
# @option params [String] :earlier_than (nil) ISO 8601 format time to filter notifications earlier than specified time
# @option params [Array] :ids (nil) Array of specific notification IDs to destroy
# @return [JSON] count: number of destroyed notification records, notifications: destroyed notifications
def destroy_all
```
### 4. Routes Configuration
**File**: Routes will be automatically generated by the existing `notify_to` helper
The route will be: `POST /:target_type/:target_id/notifications/destroy_all`
### 5. View Templates
**Files**:
- `app/views/activity_notification/notifications/default/destroy_all.js.erb`
- Template generators will need to be updated to include the new view
### 6. Swagger API Documentation
**File**: Update Swagger documentation to include the new bulk destroy endpoint
### 7. Generator Templates
**Files**: Update controller generator templates to include the new `destroy_all` action:
- `lib/generators/templates/controllers/notifications_api_controller.rb`
- `lib/generators/templates/controllers/notifications_controller.rb`
- `lib/generators/templates/controllers/notifications_with_devise_controller.rb`
## Implementation Details
### Filter Options Support
The bulk destroy API will support the same filtering options as the existing `open_all` functionality:
- `filtered_by_type`: Filter by notifiable type
- `filtered_by_group_type` + `filtered_by_group_id`: Filter by group
- `filtered_by_key`: Filter by notification key
- `later_than` / `earlier_than`: Filter by time range
- `ids`: Array of specific notification IDs (new option for precise control)
### Safety Considerations
1. **Validation**: Ensure all notifications belong to the specified target
2. **Permissions**: Leverage existing authentication/authorization patterns
3. **Soft Delete**: Consider if soft delete should be supported (follow existing destroy pattern)
4. **Callbacks**: Ensure any existing destroy callbacks are properly triggered
### Performance Considerations
1. **Batch Operations**: Use `destroy_all` for efficient database operations
2. **Memory Usage**: For large datasets, consider pagination or streaming
3. **Callbacks**: Balance between performance and callback execution
### Error Handling
1. **Partial Failures**: Handle cases where some notifications can't be destroyed
2. **Validation Errors**: Provide meaningful error messages
3. **Authorization Errors**: Consistent with existing error handling patterns
## Testing Requirements
### Unit Tests
- Test `NotificationApi#destroy_all_of` method
- Test `Target#destroy_all_notifications` method
- Test controller actions for both web and API versions
### Integration Tests
- Test complete request/response cycle
- Test with various filter combinations
- Test error scenarios
### Performance Tests
- Test with large datasets
- Verify efficient database queries
## Migration Considerations
- No database schema changes required
- Backward compatible addition
- Follows existing patterns and conventions
## Documentation Updates
- Update README.md with new bulk destroy functionality
- Update API documentation
- Update controller documentation
- Add examples to documentation
## Alternative Implementation Options
### Option 1: Single Endpoint with Multiple IDs
Instead of filter-based bulk destroy, accept an array of notification IDs:
```
POST /:target_type/:target_id/notifications/destroy_all
Body: { "ids": [1, 2, 3, 4, 5] }
```
### Option 2: RESTful Bulk Operations
Follow RESTful conventions with a bulk operations endpoint:
```
POST /:target_type/:target_id/notifications/bulk
Body: { "action": "destroy", "filters": {...} }
```
### Option 3: Query Parameter Approach
Use existing destroy endpoint with query parameters:
```
DELETE /:target_type/:target_id/notifications?ids[]=1&ids[]=2&ids[]=3
```
## Recommended Approach
The proposed implementation follows the existing pattern established by `open_all` functionality, making it consistent with the current codebase architecture. This approach provides:
1. **Consistency**: Matches existing bulk operation patterns
2. **Flexibility**: Supports various filtering options
3. **Safety**: Leverages existing validation and authorization
4. **Performance**: Uses efficient bulk database operations
5. **Maintainability**: Follows established code organization
The implementation should prioritize the filter-based approach (similar to `open_all`) while also supporting the `ids` parameter for precise control when needed.

# Implementation Plan
## Problem 1: Mongoid ORM Compatibility Issue with ID Array Filtering
### Issue Description
The bulk destroy functionality works correctly with ActiveRecord ORM but fails with Mongoid ORM. Specifically, the test case `context 'with ids options'` in `spec/concerns/apis/notification_api_spec.rb` is failing.
**Location**: `lib/activity_notification/apis/notification_api.rb` line 440
**Problematic Code**:
```ruby
target_notifications = target_notifications.where(id: options[:ids])
```
### Root Cause Analysis
The issue stems from different query syntax requirements between ActiveRecord and Mongoid when filtering by an array of IDs:
1. **ActiveRecord**: Uses `where(id: [1, 2, 3])` which automatically translates to SQL `WHERE id IN (1, 2, 3)`
2. **Mongoid**: Requires explicit `$in` operator syntax for array matching: `where(id: { '$in' => [1, 2, 3] })`
### Current Implementation Problem
The current implementation uses ActiveRecord syntax:
```ruby
target_notifications = target_notifications.where(id: options[:ids])
```
This works for ActiveRecord but fails for Mongoid because Mongoid doesn't automatically interpret an array as an `$in` operation.
### Expected Behavior
- When `options[:ids]` contains `[notification1.id, notification2.id]`, only notifications with those specific IDs should be destroyed
- The filtering should work consistently across both ActiveRecord and Mongoid ORMs
- Other filter options should still be applied in combination with ID filtering
### Test Case Analysis
The failing test:
```ruby
it "destroys notifications with specified IDs only" do
notification_to_destroy = @user_1.notifications.first
described_class.destroy_all_of(@user_1, { ids: [notification_to_destroy.id] })
expect(@user_1.notifications.count).to eq(1)
expect(@user_1.notifications.first).not_to eq(notification_to_destroy)
end
```
This test expects that when an array of IDs is provided, only those specific notifications are destroyed.
### Solution Strategy
Implement ORM-specific ID filtering logic that:
1. **Detection**: Check the current ORM configuration using `ActivityNotification.config.orm`
2. **ActiveRecord Path**: Use existing `where(id: options[:ids])` syntax
3. **Mongoid Path**: Use `where(id: { '$in' => options[:ids] })` syntax
4. **Dynamoid Path**: Use `where(‘id.in‘: options[:ids])` syntax
### Implementation Plan
1. **Conditional Logic**: Add ORM detection in the `destroy_all_of` method
2. **Mongoid Syntax**: Use `{ '$in' => options[:ids] }` for Mongoid
3. **Backward Compatibility**: Ensure ActiveRecord continues to work as before
4. **Testing**: Verify both ORMs work correctly with the new implementation
### Code Changes Required
**File**: `lib/activity_notification/apis/notification_api.rb`
**Method**: `destroy_all_of` (around line 440)
Replace:
```ruby
if options[:ids].present?
target_notifications = target_notifications.where(id: options[:ids])
end
```
With ORM-specific logic:
```ruby
if options[:ids].present?
case ActivityNotification.config.orm
when :mongoid
target_notifications = target_notifications.where(id: { '$in' => options[:ids] })
when :dynamoid
target_notifications = target_notifications.where('id.in': options[:ids])
else # :active_record
target_notifications = target_notifications.where(id: options[:ids])
end
end
```
### Testing Requirements
1. **Unit Tests**: Ensure the method works with both ActiveRecord and Mongoid
2. **Integration Tests**: Verify the complete destroy_all functionality
3. **Regression Tests**: Ensure existing functionality remains intact
### Risk Assessment
- **Low Risk**: The change is isolated to the ID filtering logic
- **Backward Compatible**: ActiveRecord behavior remains unchanged
- **Well-Tested**: Existing test suite will catch any regressions
### Future Considerations
- Consider extracting ORM-specific query logic into a helper method if more similar cases arise
- Document the ORM differences for future developers
- Consider adding similar logic to other methods that might have the same issue
---
## Problem 2: Add IDs Parameter to open_all API
### Issue Description
Enhance the `open_all_of` method to support the `ids` parameter functionality, similar to the implementation in `destroy_all_of`. This will allow users to open specific notifications by providing an array of notification IDs.
### Current State Analysis
#### Existing open_all_of Method
**Location**: `lib/activity_notification/apis/notification_api.rb` (around line 415)
**Current Implementation**:
```ruby
def open_all_of(target, options = {})
opened_at = options[:opened_at] || Time.current
target_unopened_notifications = target.notifications.unopened_only.filtered_by_options(options)
opened_notifications = target_unopened_notifications.to_a.map { |n| n.opened_at = opened_at; n }
target_unopened_notifications.update_all(opened_at: opened_at)
opened_notifications
end
```
**Current Parameters**:
- `opened_at`: Time to set to opened_at of the notification record
- `filtered_by_type`: Notifiable type for filter
- `filtered_by_group`: Group instance for filter
- `filtered_by_group_type`: Group type for filter, valid with :filtered_by_group_id
- `filtered_by_group_id`: Group instance id for filter, valid with :filtered_by_group_type
- `filtered_by_key`: Key of the notification for filter
- `later_than`: ISO 8601 format time to filter notification index later than specified time
- `earlier_than`: ISO 8601 format time to filter notification index earlier than specified time
### Proposed Enhancement
#### Add IDs Parameter Support
Add support for the `ids` parameter to allow opening specific notifications by their IDs, following the same pattern as `destroy_all_of`.
#### Updated Method Signature
```ruby
# @option options [Array] :ids (nil) Array of specific notification IDs to open
def open_all_of(target, options = {})
```
### Implementation Strategy
1. **Reuse existing pattern**: Follow the same ORM-specific ID filtering logic implemented in `destroy_all_of`
2. **Maintain backward compatibility**: Ensure existing functionality remains unchanged
3. **Consistent behavior**: Apply ID filtering after other filters, similar to destroy_all_of
### Code Changes Required
#### 1. Update Method Documentation
**File**: `lib/activity_notification/apis/notification_api.rb`
Add the `ids` parameter to the method documentation:
```ruby
# @option options [Array] :ids (nil) Array of specific notification IDs to open
```
#### 2. Add ID Filtering Logic
Insert the same ORM-specific ID filtering logic used in `destroy_all_of`:
```ruby
def open_all_of(target, options = {})
opened_at = options[:opened_at] || Time.current
target_unopened_notifications = target.notifications.unopened_only.filtered_by_options(options)
# Add ID filtering logic (same as destroy_all_of)
if options[:ids].present?
# :nocov:
case ActivityNotification.config.orm
when :mongoid
target_unopened_notifications = target_unopened_notifications.where(id: { '$in' => options[:ids] })
when :dynamoid
target_unopened_notifications = target_unopened_notifications.where('id.in': options[:ids])
else # :active_record
target_unopened_notifications = target_unopened_notifications.where(id: options[:ids])
end
# :nocov:
end
opened_notifications = target_unopened_notifications.to_a.map { |n| n.opened_at = opened_at; n }
target_unopened_notifications.update_all(opened_at: opened_at)
opened_notifications
end
```
#### 3. Update Controller Actions
The controller actions that use `open_all_of` should be updated to accept and pass through the `ids` parameter:
**Files to Update**:
- `app/controllers/activity_notification/notifications_controller.rb`
- `app/controllers/activity_notification/notifications_api_controller.rb`
**Parameter Addition**:
```ruby
# Add :ids to permitted parameters
params.permit(:ids => [])
```
#### 4. Update API Documentation
**File**: `lib/activity_notification/controllers/concerns/swagger/notifications_api.rb`
Add `ids` parameter to the Swagger documentation for the open_all endpoint:
```ruby
parameter do
key :name, :ids
key :in, :query
key :description, 'Array of specific notification IDs to open'
key :required, false
key :type, :array
items do
key :type, :string
end
end
```
### Testing Requirements
#### 1. Add Test Cases
**File**: `spec/concerns/apis/notification_api_spec.rb`
Add test cases similar to the `destroy_all_of` tests:
```ruby
context 'with ids options' do
it "opens notifications with specified IDs only" do
notification_to_open = @user_1.notifications.first
described_class.open_all_of(@user_1, { ids: [notification_to_open.id] })
expect(@user_1.notifications.unopened_only.count).to eq(1)
expect(@user_1.notifications.opened_only!.count).to eq(1)
expect(@user_1.notifications.opened_only!.first).to eq(notification_to_open)
end
it "applies other filter options when ids are specified" do
notification_to_open = @user_1.notifications.first
described_class.open_all_of(@user_1, {
ids: [notification_to_open.id],
filtered_by_key: 'non_existent_key'
})
expect(@user_1.notifications.unopened_only.count).to eq(2)
expect(@user_1.notifications.opened_only!.count).to eq(0)
end
it "only opens unopened notifications even when opened notification IDs are provided" do
# First open one notification
notification_to_open = @user_1.notifications.first
notification_to_open.open!
# Try to open it again using ids parameter
described_class.open_all_of(@user_1, { ids: [notification_to_open.id] })
# Should not affect the count since it was already opened
expect(@user_1.notifications.unopened_only.count).to eq(1)
expect(@user_1.notifications.opened_only!.count).to eq(1)
end
end
```
#### 2. Update Controller Tests
**File**: `spec/controllers/notifications_api_controller_shared_examples.rb`
Add test cases for the API controller to ensure the `ids` parameter is properly handled:
```ruby
context 'with ids parameter' do
it "opens only specified notifications" do
notification_to_open = @user.notifications.first
post open_all_notification_path(@user), params: { ids: [notification_to_open.id] }
expect(response).to have_http_status(200)
expect(@user.notifications.unopened_only.count).to eq(1)
expect(@user.notifications.opened_only!.count).to eq(1)
end
end
```
### Benefits
#### 1. Consistency
- Provides consistent API between `open_all_of` and `destroy_all_of` methods
- Both methods now support the same filtering options including `ids`
#### 2. Flexibility
- Allows precise control over which notifications to open
- Enables batch operations on specific notifications
- Supports complex filtering combinations
#### 3. Performance
- Efficient database operations using bulk updates
- Reduces the need for multiple individual open operations
#### 4. User Experience
- Provides the functionality requested in the original issue
- Enables building more sophisticated notification management UIs
### Implementation Considerations
#### 1. Backward Compatibility
- All existing functionality remains unchanged
- New `ids` parameter is optional
- Existing tests should continue to pass
#### 2. ORM Compatibility
- Uses the same ORM-specific logic as `destroy_all_of`
- Tested across ActiveRecord, Mongoid, and Dynamoid
#### 3. Security
- ID filtering is applied after target validation
- Only notifications belonging to the specified target can be opened
- Follows existing security patterns
#### 4. Error Handling
- Invalid IDs are silently ignored (consistent with existing behavior)
- Non-existent notifications don't cause errors
- Maintains existing error handling patterns
### Risk Assessment
- **Low Risk**: Follows established patterns from `destroy_all_of`
- **Backward Compatible**: ActiveRecord behavior remains unchanged
- **Well-Tested**: Existing test suite will catch any regressions
### Implementation Timeline
1. **Phase 1**: Update `open_all_of` method with ID filtering logic
2. **Phase 2**: Add comprehensive test cases
3. **Phase 3**: Update controller actions and API documentation
4. **Phase 4**: Update controller tests and integration tests
5. **Phase 5**: Documentation updates and final testing

# Design Document
## Overview
This design outlines the approach for upgrading activity_notification's Dynamoid dependency from v3.1.0 to v3.11.0. The upgrade involves updating namespace references, method signatures, and class hierarchies that have changed between these versions, while maintaining backward compatibility and preparing useful enhancements for upstream contribution to Dynamoid.
## Architecture
### Current Architecture
- **Dynamoid Extension**: `lib/activity_notification/orm/dynamoid/extension.rb` contains monkey patches extending Dynamoid v3.1.0
- **ORM Integration**: `lib/activity_notification/orm/dynamoid.rb` provides ActivityNotification-specific query methods
- **Dependency Management**: Gemspec pins Dynamoid to exactly v3.1.0
### Target Architecture
- **Updated Extension**: Refactored extension file compatible with Dynamoid v3.11.0 namespaces
- **Backward Compatibility**: Maintained API surface for existing applications
- **Upstream Preparation**: Clean, well-documented code ready for Dynamoid contribution
- **Flexible Dependency**: Version range allowing v3.11.0+ while preventing breaking v4.0 changes
## Components and Interfaces
### 1. Gemspec Update
**File**: `activity_notification.gemspec`
**Changes**:
- Update Dynamoid dependency from development dependency `'3.1.0'` to runtime dependency `'>= 3.11.0', '< 4.0'`
- Change dependency type from `add_development_dependency` to `add_dependency` for production use
- Ensure compatibility with Rails version constraints
### 2. Extension Module Refactoring
**File**: `lib/activity_notification/orm/dynamoid/extension.rb`
#### 2.1 Critical Namespace Changes
Based on analysis of Dynamoid v3.1.0 vs v3.11.0:
**Query and Scan Class Locations**:
- **v3.1.0**: `Dynamoid::AdapterPlugin::Query` and `Dynamoid::AdapterPlugin::Scan`
- **v3.11.0**: `Dynamoid::AdapterPlugin::AwsSdkV3::Query` and `Dynamoid::AdapterPlugin::AwsSdkV3::Scan`
**Method Signature Changes**:
- **v3.1.0**: `Query.new(client, table, opts = {})`
- **v3.11.0**: `Query.new(client, table, key_conditions, non_key_conditions, options)`
#### 2.2 Removed Constants and Methods
**Constants removed in v3.11.0**:
- `FIELD_MAP` - Used for condition mapping
- `RANGE_MAP` - Used for range condition mapping
- `attribute_value_list()` method - No longer exists
**New Architecture in v3.11.0**:
- Uses `FilterExpressionConvertor` for building filter expressions
- Uses expression attribute names and values instead of legacy condition format
- Middleware pattern for handling backoff, limits, and pagination
#### 2.3 Class Hierarchy Updates Required
- Update inheritance from `::Dynamoid::AdapterPlugin::Query` to `::Dynamoid::AdapterPlugin::AwsSdkV3::Query`
- Update inheritance from `::Dynamoid::AdapterPlugin::Scan` to `::Dynamoid::AdapterPlugin::AwsSdkV3::Scan`
- Remove references to `FIELD_MAP`, `RANGE_MAP`, and `attribute_value_list()`
- Adapt to new filter expression format
### 3. Core Functionality Preservation
**Methods to Maintain**:
- `none()` - Returns empty result set
- `limit()` - Aliases to `record_limit()`
- `exists?()` - Checks if records exist
- `update_all()` - Batch update operations
- `serializable_hash()` - Array serialization
- Null/not_null operators for query filtering
- Uniqueness validation support
### 4. Upstream Contribution Preparation
**Target Methods for Contribution**:
- `Chain#none` - Useful empty result pattern
- `Chain#limit` - More intuitive alias for `record_limit`
- `Chain#exists?` - Common query pattern
- `Chain#update_all` - Batch operations
- Null operator extensions - Enhanced query capabilities
- Uniqueness validator - Common validation need
## Data Models
### Extension Points
```ruby
# Current structure (v3.1.0)
module Dynamoid
module Criteria
class Chain
# Extension methods work with @query hash
end
end
module AdapterPlugin
class AwsSdkV3
class Query < ::Dynamoid::AdapterPlugin::Query
# Uses FIELD_MAP, RANGE_MAP, attribute_value_list
def query_filter
# Legacy condition format
end
end
end
end
end
# Target structure (v3.11.0) - CONFIRMED
module Dynamoid
module Criteria
class Chain
# Extension methods work with @where_conditions object
# Uses KeyFieldsDetector and WhereConditions classes
end
end
module AdapterPlugin
class AwsSdkV3
class Query < ::Dynamoid::AdapterPlugin::AwsSdkV3::Query # CHANGED NAMESPACE
# Uses FilterExpressionConvertor instead of FIELD_MAP
# No more query_filter method - uses filter_expression
def initialize(client, table, key_conditions, non_key_conditions, options)
# CHANGED SIGNATURE
end
end
end
end
end
```
### Critical Breaking Changes
1. **Query/Scan inheritance path changed**: `::Dynamoid::AdapterPlugin::Query` → `::Dynamoid::AdapterPlugin::AwsSdkV3::Query`
2. **Constructor signature changed**: Single options hash → separate key/non-key conditions + options
3. **Filter building changed**: `FIELD_MAP`/`RANGE_MAP` → `FilterExpressionConvertor`
4. **Method removal**: `attribute_value_list()`, `query_filter()`, `scan_filter()` methods removed
### Configuration Changes
- No breaking changes to ActivityNotification configuration
- Maintain existing API for `acts_as_notification_target`, `acts_as_notifiable`, etc.
- Preserve all existing query method signatures
## Error Handling
### Migration Strategy
1. **Gradual Rollout**: Support version range to allow gradual adoption
2. **Fallback Mechanisms**: Detect Dynamoid version and use appropriate code paths if needed
3. **Clear Error Messages**: Provide helpful errors if incompatible versions are used
### Exception Handling
- **NameError**: Handle missing classes/modules gracefully
- **NoMethodError**: Provide fallbacks for changed method signatures
- **ArgumentError**: Handle parameter changes in Dynamoid methods
### Validation
- Runtime checks for critical Dynamoid functionality
- Test coverage for all supported Dynamoid versions
- Integration tests with real DynamoDB operations
## Testing Strategy
### Unit Tests
- Test all extension methods with Dynamoid v3.11.0
- Verify namespace resolution works correctly
- Test error handling for edge cases
### Integration Tests
- Full ActivityNotification workflow with DynamoDB
- Performance regression testing
- Memory usage validation
### Compatibility Tests
- Test with multiple Dynamoid versions in range
- Verify no breaking changes for existing applications
- Test upgrade path from v3.1.0 to v3.11.0
### Upstream Preparation Tests
- Isolated tests for each method proposed for contribution
- Documentation examples that work standalone
- Performance benchmarks for contributed methods
## Implementation Phases
### Phase 1: Research and Analysis ✅ COMPLETED
- ✅ Compare Dynamoid v3.1.0 vs v3.11.0 source code
- ✅ Identify all namespace and method signature changes
- ✅ Create compatibility matrix
**Key Findings**:
- Query/Scan classes moved from `AdapterPlugin::` to `AdapterPlugin::AwsSdkV3::`
- Constructor signatures completely changed
- FIELD_MAP/RANGE_MAP constants removed
- Filter building now uses FilterExpressionConvertor
- Legacy query_filter/scan_filter methods removed
### Phase 2: Core Updates
- Update gemspec dependency
- Refactor extension.rb for new namespaces
- Maintain existing functionality
### Phase 3: Testing and Validation
- Update test suite for new Dynamoid version
- Run comprehensive integration tests using `AN_ORM=dynamoid bundle exec rspec`
- Fix failing tests to ensure all Dynamoid-related functionality works
- Performance validation
- Verify all existing test scenarios pass with new Dynamoid version
### Phase 4: Upstream Preparation
- Extract reusable methods into separate modules
- Create documentation and examples
- Prepare pull requests for Dynamoid project
### Phase 5: Documentation and Release
- Update CHANGELOG with breaking changes
- Update README with version requirements
- Release new version with proper semantic versioning
## Risk Mitigation
### Breaking Changes
- Use version range to prevent automatic v4.0 adoption
- Provide clear upgrade documentation
- Maintain backward compatibility where possible
### Performance Impact
- Benchmark critical query operations
- Monitor memory usage changes
- Test with large datasets
### Upstream Contribution Risks

# Upstream Contributions for Dynamoid
This document outlines the improvements made to ActivityNotification's Dynamoid integration that could be contributed back to the Dynamoid project.
## 1. None Method Implementation
### Overview
The `none()` method provides an empty query result set, similar to ActiveRecord's `none` method. This is useful for conditional queries and maintaining consistent interfaces.
### Implementation
```ruby
module Dynamoid
module Criteria
class None < Chain
def ==(other)
other.is_a?(None)
end
def records
[]
end
def count
0
end
def delete_all
end
def empty?
true
end
end
class Chain
# Return new none object
def none
None.new(self.source)
end
end
module ClassMethods
define_method(:none) do |*args, &blk|
chain = Dynamoid::Criteria::Chain.new(self)
chain.send(:none, *args, &blk)
end
end
end
end
```
### Benefits
- Provides consistent API with ActiveRecord
- Enables conditional query building without complex logic
- Returns predictable empty results for edge cases
- Maintains chainable query interface
### Usage Examples
```ruby
# Conditional queries
users = condition ? User.where(active: true) : User.none
# Default empty state
def search_results(query)
return User.none if query.blank?
User.where(name: query)
end
```
### Tests
```ruby
describe "none method" do
it "returns empty results" do
expect(User.none.count).to eq(0)
expect(User.none.to_a).to eq([])
expect(User.none).to be_empty
end
it "is chainable" do
expect(User.where(active: true).none.count).to eq(0)
end
end
```
## 2. Limit Method Implementation
### Overview
The `limit()` method provides a more intuitive alias for Dynamoid's `record_limit()` method, matching ActiveRecord's interface and improving developer experience.
### Implementation
```ruby
module Dynamoid
module Criteria
class Chain
# Set query result limit as record_limit of Dynamoid
# @scope class
# @param [Integer] limit Query result limit as record_limit
# @return [Dynamoid::Criteria::Chain] Database query of filtered notifications or subscriptions
def limit(limit)
record_limit(limit)
end
end
end
end
```
### Benefits
- Provides familiar ActiveRecord-style method name
- Improves code readability and developer experience
- Maintains backward compatibility with existing `record_limit` method
- Reduces cognitive load when switching between ORMs
### Usage Examples
```ruby
# More intuitive than record_limit(10)
User.limit(10)
# Chainable with other methods
User.where(active: true).limit(5)
# Consistent with ActiveRecord patterns
def recent_users(count = 10)
User.where(created_at: Time.current.beginning_of_day..).limit(count)
end
```
### Tests
```ruby
describe "limit method" do
it "limits query results" do
create_list(:user, 20)
expect(User.limit(5).count).to eq(5)
end
it "is chainable" do
create_list(:user, 20, active: true)
result = User.where(active: true).limit(3)
expect(result.count).to eq(3)
end
it "behaves identically to record_limit" do
create_list(:user, 10)
expect(User.limit(5).to_a).to eq(User.record_limit(5).to_a)
end
end
```
## 3. Exists? Method Implementation
### Overview
The `exists?()` method provides an efficient way to check if any records match the current query criteria without loading the actual records, similar to ActiveRecord's `exists?` method.
### Implementation
```ruby
module Dynamoid
module Criteria
class Chain
# Return if records exist
# @scope class
# @return [Boolean] If records exist
def exists?
record_limit(1).count > 0
end
end
end
end
```
### Benefits
- Provides efficient existence checking without loading full records
- Matches ActiveRecord's interface for consistency
- Optimizes performance by limiting query to single record
- Enables cleaner conditional logic in applications
### Performance Considerations
- Uses `record_limit(1)` to minimize data transfer
- Only performs count operation, not full record retrieval
- Significantly faster than loading all records just to check existence
### Usage Examples
```ruby
# Check if any active users exist
if User.where(active: true).exists?
# Process active users
end
# Conditional processing
def process_notifications
return unless Notification.where(unread: true).exists?
# Process unread notifications
end
# Validation logic
def validate_unique_email
errors.add(:email, 'already taken') if User.where(email: email).exists?
end
```
### Tests
```ruby
describe "exists? method" do
it "returns true when records exist" do
create(:user, active: true)
expect(User.where(active: true).exists?).to be true
end
it "returns false when no records exist" do
expect(User.where(active: true).exists?).to be false
end
it "is efficient and doesn't load full records" do
create_list(:user, 100, active: true)
# Should be much faster than loading all records
expect {
User.where(active: true).exists?
}.to perform_faster_than {
User.where(active: true).to_a.any?
}
end
end
```
## 4. Update_all Method Implementation
### Overview
The `update_all()` method provides batch update functionality for Dynamoid queries, similar to ActiveRecord's `update_all` method. This enables efficient bulk updates without loading individual records.
### Implementation
```ruby
module Dynamoid
module Criteria
class Chain
# Update all records matching the current criteria
# TODO: Make this batch operation more efficient
def update_all(conditions = {})
each do |document|
document.update_attributes(conditions)
end
end
end
end
end
```
### Benefits
- Provides familiar ActiveRecord-style batch update interface
- Enables bulk operations on query results
- Maintains consistency with other ORM patterns
- Simplifies common bulk update scenarios
### Current Implementation Notes
- Current implementation iterates through each record individually
- Future optimization could implement true batch operations
- Maintains compatibility with existing Dynamoid update patterns
### Usage Examples
```ruby
# Bulk status updates
User.where(active: false).update_all(status: 'inactive')
# Batch timestamp updates
Notification.where(read: false).update_all(updated_at: Time.current)
# Conditional bulk updates
def mark_old_notifications_as_read
Notification.where(created_at: ..1.week.ago).update_all(read: true)
end
```
### Future Optimization Opportunities
```ruby
# Potential batch implementation using DynamoDB batch operations
def update_all(conditions = {})
# Group updates into batches of 25 (DynamoDB limit)
all.each_slice(25) do |batch|
batch_requests = batch.map do |document|
{
update_item: {
table_name: document.class.table_name,
key: document.key,
update_expression: build_update_expression(conditions),
expression_attribute_values: conditions
}
}
end
dynamodb_client.batch_write_item(request_items: {
document.class.table_name => batch_requests
})
end
end
```
### Tests
```ruby
describe "update_all method" do
it "updates all matching records" do
users = create_list(:user, 5, active: true)
User.where(active: true).update_all(status: 'updated')
users.each(&:reload)
expect(users.map(&:status)).to all(eq('updated'))
end
it "works with empty result sets" do
expect {
User.where(active: false).update_all(status: 'updated')
}.not_to raise_error
end
it "updates only matching records" do
active_users = create_list(:user, 3, active: true)
inactive_users = create_list(:user, 2, active: false)
User.where(active: true).update_all(status: 'updated')
active_users.each(&:reload)
inactive_users.each(&:reload)
expect(active_users.map(&:status)).to all(eq('updated'))
expect(inactive_users.map(&:status)).to all(be_nil)
end
end
```
## 5. Null Operator Extensions
### Overview
Enhanced null value handling in Dynamoid queries, providing more intuitive ways to query for null and non-null values. This improves the developer experience when working with optional attributes.
### Implementation Context
The null operator extensions are primarily used within the UniquenessValidator but demonstrate a pattern that could be useful throughout Dynamoid:
```ruby
# From UniquenessValidator implementation
def filter_criteria(criteria, document, attribute)
value = document.read_attribute(attribute)
value.nil? ? criteria.where("#{attribute}.null" => true) : criteria.where(attribute => value)
end
```
### Benefits
- Provides intuitive null value querying
- Improves validation logic for optional fields
- Enables more expressive query conditions
- Maintains consistency with DynamoDB's null handling
### Usage Examples
```ruby
# Query for records with null values
User.where("email.null" => true)
# Query for records with non-null values
User.where("email.null" => false)
# In validation contexts
def validate_uniqueness_with_nulls
scope_criteria = base_criteria
if email.nil?
scope_criteria.where("email.null" => true)
else
scope_criteria.where(email: email)
end
end
```
### Potential Extensions
```ruby
module Dynamoid
module Criteria
class Chain
# Add convenience methods for null queries
def where_null(attribute)
where("#{attribute}.null" => true)
end
def where_not_null(attribute)
where("#{attribute}.null" => false)
end
end
end
end
```
### Tests
```ruby
describe "null operator extensions" do
it "finds records with null values" do
user_with_email = create(:user, email: 'test@example.com')
user_without_email = create(:user, email: nil)
results = User.where("email.null" => true)
expect(results).to include(user_without_email)
expect(results).not_to include(user_with_email)
end
it "finds records with non-null values" do
user_with_email = create(:user, email: 'test@example.com')
user_without_email = create(:user, email: nil)
results = User.where("email.null" => false)
expect(results).to include(user_with_email)
expect(results).not_to include(user_without_email)
end
end
```
## 6. Uniqueness Validator Implementation
### Overview
A comprehensive UniquenessValidator for Dynamoid that provides ActiveRecord-style uniqueness validation with support for scoped validation and null value handling.
### Implementation
```ruby
module Dynamoid
module Validations
# Validates whether or not a field is unique against the records in the database.
class UniquenessValidator < ActiveModel::EachValidator
# Validate the document for uniqueness violations.
# @param [Document] document The document to validate.
# @param [Symbol] attribute The name of the attribute.
# @param [Object] value The value of the object.
def validate_each(document, attribute, value)
return unless validation_required?(document, attribute)
if not_unique?(document, attribute, value)
error_options = options.except(:scope).merge(value: value)
document.errors.add(attribute, :taken, **error_options)
end
end
private
# Are we required to validate the document?
# @api private
def validation_required?(document, attribute)
document.new_record? ||
document.send("attribute_changed?", attribute.to_s) ||
scope_value_changed?(document)
end
# Scope reference has changed?
# @api private
def scope_value_changed?(document)
Array.wrap(options[:scope]).any? do |item|
document.send("attribute_changed?", item.to_s)
end
end
# Check whether a record is uniqueness.
# @api private
def not_unique?(document, attribute, value)
klass = document.class
while klass.superclass.respond_to?(:validators) && klass.superclass.validators.include?(self)
klass = klass.superclass
end
criteria = create_criteria(klass, document, attribute, value)
criteria.exists?
end
# Create the validation criteria.
# @api private
def create_criteria(base, document, attribute, value)
criteria = scope(base, document)
filter_criteria(criteria, document, attribute)
end
# @api private
def scope(criteria, document)
Array.wrap(options[:scope]).each do |item|
criteria = filter_criteria(criteria, document, item)
end
criteria
end
# Filter the criteria.
# @api private
def filter_criteria(criteria, document, attribute)
value = document.read_attribute(attribute)
value.nil? ? criteria.where("#{attribute}.null" => true) : criteria.where(attribute => value)
end
end
end
end
```
### Benefits
- Provides ActiveRecord-compatible uniqueness validation
- Supports scoped uniqueness validation
- Handles null values correctly
- Optimizes validation by only checking when necessary
- Supports inheritance hierarchies
### Key Features
1. **Conditional Validation**: Only validates when record is new or attribute has changed
2. **Scope Support**: Validates uniqueness within specified scopes
3. **Null Handling**: Properly handles null values in uniqueness checks
4. **Inheritance Support**: Works correctly with model inheritance
5. **Performance Optimization**: Uses `exists?` method for efficient checking
### Usage Examples
```ruby
class User
include Dynamoid::Document
field :email, :string
field :username, :string
field :organization_id, :string
# Basic uniqueness validation
validates :email, uniqueness: true
# Scoped uniqueness validation
validates :username, uniqueness: { scope: :organization_id }
# With custom error message
validates :email, uniqueness: { message: 'is already registered' }
end
# Usage in models
user = User.new(email: 'existing@example.com')
user.valid? # => false
user.errors[:email] # => ["has already been taken"]
```
### Tests
```ruby
describe "UniquenessValidator" do
describe "basic uniqueness" do
it "validates uniqueness of email" do
create(:user, email: 'test@example.com')
duplicate = build(:user, email: 'test@example.com')
expect(duplicate).not_to be_valid
expect(duplicate.errors[:email]).to include('has already been taken')
end
it "allows unique emails" do
create(:user, email: 'test1@example.com')
unique = build(:user, email: 'test2@example.com')
expect(unique).to be_valid
end
end
describe "scoped uniqueness" do
it "validates uniqueness within scope" do
org1 = create(:organization)
org2 = create(:organization)
create(:user, username: 'john', organization: org1)
# Same username in different org should be valid
user_different_org = build(:user, username: 'john', organization: org2)
expect(user_different_org).to be_valid
# Same username in same org should be invalid
user_same_org = build(:user, username: 'john', organization: org1)
expect(user_same_org).not_to be_valid
end
end
describe "null value handling" do
it "allows multiple records with null values" do
create(:user, email: nil)
user_with_null = build(:user, email: nil)
expect(user_with_null).to be_valid
end
end
describe "performance optimization" do
it "only validates when necessary" do
user = create(:user, email: 'test@example.com')
# Should not validate when no changes
expect(User).not_to receive(:where)
user.valid?
# Should validate when email changes
user.email = 'new@example.com'
expect(User).to receive(:where).and_call_original
user.valid?
end
end
end

# Issue #202: Instance-Level Subscriptions - Design
## Schema Changes
### Subscription Table
Add two nullable polymorphic columns to the `subscriptions` table:
```
notifiable_type :string, index: true, null: true
notifiable_id :bigint, index: true, null: true (or :string for Mongoid/Dynamoid)
```
- `NULL` notifiable fields = key-level subscription (existing behavior)
- Non-NULL notifiable fields = instance-level subscription
### Unique Constraint
Replace the existing unique index:
```
# Before
add_index :subscriptions, [:target_type, :target_id, :key], unique: true
# After
add_index :subscriptions, [:target_type, :target_id, :key, :notifiable_type, :notifiable_id],
unique: true, name: 'index_subscriptions_uniqueness'
```
This allows:
- One key-level subscription per (target, key) where notifiable is NULL
- One instance-level subscription per (target, key, notifiable) combination
**Note:** Most databases treat NULL as distinct in unique indexes, so `(user1, 'comment.default', NULL, NULL)` and `(user1, 'comment.default', 'Post', 1)` are considered different. For databases that don't, a partial/conditional index may be needed.
### Model Validations
Update uniqueness validation in all three ORM implementations:
```ruby
# ActiveRecord
validates :key, presence: true, uniqueness: { scope: [:target, :notifiable_type, :notifiable_id] }
# Mongoid
validates :key, presence: true, uniqueness: { scope: [:target_type, :target_id, :notifiable_type, :notifiable_id] }
# Dynamoid
validates :key, presence: true, uniqueness: { scope: :target_key }
# (Dynamoid uses composite keys, needs separate handling)
```
## Core Logic Changes
### 1. Subscription Model (All ORMs)
Add `belongs_to :notifiable` polymorphic association (optional):
```ruby
# ActiveRecord
belongs_to :notifiable, polymorphic: true, optional: true
# Mongoid
belongs_to_polymorphic_xdb_record :notifiable, optional: true
# Dynamoid
belongs_to_composite_xdb_record :notifiable, optional: true
```
Add scopes for filtering:
```ruby
scope :key_level_only, -> { where(notifiable_type: nil) }
scope :instance_level_only, -> { where.not(notifiable_type: nil) }
scope :for_notifiable, ->(notifiable) { where(notifiable_type: notifiable.class.name, notifiable_id: notifiable.id) }
```
### 2. Subscriber Concern (`models/concerns/subscriber.rb`)
Update `_subscribes_to_notification?` to only check key-level subscriptions:
```ruby
def _subscribes_to_notification?(key, subscribe_as_default = ...)
evaluate_subscription(
subscriptions.where(key: key, notifiable_type: nil).first,
:subscribing?,
subscribe_as_default
)
end
```
Add new method for instance-level subscription check:
```ruby
def _subscribes_to_notification_for_instance?(key, notifiable, subscribe_as_default = ...)
instance_sub = subscriptions.where(key: key, notifiable_type: notifiable.class.name, notifiable_id: notifiable.id).first
instance_sub.present? && instance_sub.subscribing?
end
```
Update `find_subscription` to support optional notifiable:
```ruby
def find_subscription(key, notifiable: nil)
if notifiable
subscriptions.where(key: key, notifiable_type: notifiable.class.name, notifiable_id: notifiable.id).first
else
subscriptions.where(key: key, notifiable_type: nil).first
end
end
```
### 3. Target Concern (`models/concerns/target.rb`)
Update `subscribes_to_notification?` to accept optional notifiable:
```ruby
def subscribes_to_notification?(key, subscribe_as_default = ..., notifiable: nil)
return true unless subscription_allowed?(key)
_subscribes_to_notification?(key, subscribe_as_default) ||
(notifiable.present? && _subscribes_to_notification_for_instance?(key, notifiable, subscribe_as_default))
end
```
### 4. Notification API (`apis/notification_api.rb`)
#### `generate_notification` - Add instance-level check
```ruby
def generate_notification(target, notifiable, options = {})
key = options[:key] || notifiable.default_notification_key
if target.subscribes_to_notification?(key, notifiable: notifiable)
store_notification(target, notifiable, key, options)
end
end
```
This is the minimal change. The existing `subscribes_to_notification?` check stays in `generate_notification` (not moved to `notify`), and we extend it to also consider instance-level subscriptions.
#### `notify` - Add instance subscription targets
```ruby
def notify(target_type, notifiable, options = {})
if options[:notify_later]
notify_later(target_type, notifiable, options)
else
targets = notifiable.notification_targets(target_type, options[:pass_full_options] ? options : options[:key])
# Merge instance subscription targets, deduplicate
instance_targets = notifiable.instance_subscription_targets(target_type, options[:key])
targets = merge_targets(targets, instance_targets)
unless targets_empty?(targets)
notify_all(targets, notifiable, options)
end
end
end
```
#### New helper: `merge_targets`
```ruby
def merge_targets(targets, instance_targets)
return targets if instance_targets.blank?
# Convert to array for deduplication
all_targets = targets.respond_to?(:to_a) ? targets.to_a : Array(targets)
(all_targets + instance_targets).uniq
end
```
### 5. Notifiable Concern (`models/concerns/notifiable.rb`)
Add `instance_subscription_targets`:
```ruby
def instance_subscription_targets(target_type, key = nil)
key ||= default_notification_key
target_class_name = target_type.to_s.to_model_name
Subscription.where(
notifiable_type: self.class.name,
notifiable_id: self.id,
key: key,
subscribing: true
).where(target_type: target_class_name)
.map(&:target)
.compact
end
```
### 6. Subscription API (`apis/subscription_api.rb`)
Add `key_level_only` and `instance_level_only` scopes. No changes to existing subscribe/unsubscribe methods — they work on individual subscription records regardless of whether they're key-level or instance-level.
### 7. Controllers
Update `subscription_params` in `CommonController` to permit `notifiable_type` and `notifiable_id`.
Update `create` action to pass through notifiable params.
Update `find` action to support optional notifiable filtering.
## Async Path (`notify_later`)
The `notify_later` path serializes arguments and delegates to `NotifyJob`, which calls `notify` synchronously. Since our changes are in `notify` and `generate_notification`, the async path is automatically covered — no separate changes needed for `NotifyJob`.
## Migration Template
Update `lib/generators/templates/migrations/migration.rb` to include the new columns and updated index.
Provide a separate migration generator for existing installations:
`lib/generators/activity_notification/migration/add_notifiable_to_subscriptions_generator.rb`
## Backward Compatibility
- All existing key-level subscriptions have `notifiable_type = NULL` and `notifiable_id = NULL`
- `_subscribes_to_notification?` filters by `notifiable_type: nil`, so existing behavior is preserved
- `subscribes_to_notification?` without `notifiable:` parameter returns the same result as before
- `find_subscription(key)` without `notifiable:` returns key-level subscription as before

================================================
# Issue #202: Instance-Level Subscriptions - Requirements
## Overview
Allow targets (e.g., users) to subscribe to notifications from a specific notifiable instance, not just by notification key. For example, a user can subscribe to comment notifications on Post #1 and Post #4 only, similar to GitHub's issue subscription model.
## Background
Currently, subscriptions are key-based only. A subscription record ties a target to a notification key (e.g., `comment.default`). When `subscribes_to_notification?(key)` is checked, it looks up the subscription by `(target, key)`. This is an all-or-nothing approach — you either subscribe to all notifications of a given key or none.
## Functional Requirements
### FR-1: Instance-Level Subscription Records
- A target MUST be able to create a subscription scoped to a specific notifiable instance (e.g., Post #1) and key.
- Instance-level subscriptions are stored in the same `subscriptions` table with additional `notifiable_type` and `notifiable_id` columns (nullable).
- Existing key-only subscriptions (where `notifiable_type` and `notifiable_id` are NULL) MUST continue to work unchanged.
### FR-2: Subscription Check During Notification Generation
- When generating a notification for a target, the system MUST check:
1. Key-level subscription (existing behavior): Does the target subscribe to this key globally?
2. Instance-level subscription (new): Does the target have an active instance-level subscription for this specific notifiable and key?
- A notification MUST be generated if EITHER the key-level subscription allows it OR an active instance-level subscription exists for the notifiable.
### FR-3: Instance Subscription Targets Discovery
- When `notify` is called for a notifiable, the system MUST also discover targets that have instance-level subscriptions for that specific notifiable, in addition to the targets returned by `notification_targets`.
- Duplicate targets (appearing in both `notification_targets` and instance subscriptions) MUST be deduplicated.
### FR-4: Async Path Support
- Instance-level subscriptions MUST work with both synchronous (`notify`) and asynchronous (`notify_later`) notification paths.
### FR-5: Multi-ORM Support
- Instance-level subscriptions MUST work with all three supported ORMs: ActiveRecord, Mongoid, and Dynamoid.
### FR-6: API and Controller Support
- The subscription API and controllers MUST support creating, finding, and managing instance-level subscriptions.
- The `create` action MUST accept optional `notifiable_type` and `notifiable_id` parameters.
- The `find` action MUST support finding subscriptions by key and optionally by notifiable.
### FR-7: Backward Compatibility
- All existing subscription behavior MUST remain unchanged.
- Existing subscriptions without notifiable fields MUST continue to function as key-level subscriptions.
- The unique constraint MUST be updated to accommodate both key-level and instance-level subscriptions.
## Non-Functional Requirements
### NFR-1: Performance
- Instance-level subscription checks MUST NOT introduce N+1 query problems.
- The implementation SHOULD batch-load instance subscriptions where possible.
### NFR-2: Test Coverage
- Test coverage MUST NOT decrease from the current level (~99.7%).
- New functionality MUST have comprehensive test coverage including edge cases.
### NFR-3: Migration
- A migration generator or template MUST be provided for adding the new columns.
- The migration MUST be safe to run on existing installations (additive only, nullable columns).

# Design Document
## Overview
This design addresses the issue where background email jobs fail when notifications are destroyed before the mailer job executes. The solution involves implementing graceful error handling in the mailer functionality to catch `ActiveRecord::RecordNotFound` exceptions and handle them appropriately.
The core approach is to modify the notification email sending logic to be resilient to missing notifications while maintaining backward compatibility and proper logging.
## Architecture
### Current Flow
1. Notification is created
2. Background job is enqueued to send email
3. Job executes and looks up notification by ID
4. If notification was destroyed, job fails with `ActiveRecord::RecordNotFound`
### Proposed Flow
1. Notification is created
2. Background job is enqueued to send email
3. Job executes and attempts to look up notification by ID
4. If notification is missing:
- Catch the `ActiveRecord::RecordNotFound` exception
- Log a warning message with relevant details
- Complete the job successfully (no re-raise)
5. If notification exists, proceed with normal email sending
## Components and Interfaces
### 1. Mailer Enhancement
**Location**: `app/mailers/activity_notification/mailer.rb`
The mailer's `send_notification_email` method needs to be enhanced to handle missing notifications gracefully.
**Interface Changes**:
- Add rescue block for `ActiveRecord::RecordNotFound`
- Add logging for missing notifications
- Ensure method returns successfully even when notification is missing
### 2. Notification API Enhancement
**Location**: `lib/activity_notification/apis/notification_api.rb`
The notification email sending logic in the API needs to be enhanced to handle cases where the notification record might be missing during job execution.
**Interface Changes**:
- Add resilient notification lookup methods
- Enhance error handling in email sending workflows
- Maintain existing API compatibility
### 3. Job Enhancement
**Location**: Background job classes that send emails
Any background jobs that send notification emails need to handle missing notifications gracefully.
**Interface Changes**:
- Add error handling for missing notifications
- Ensure jobs complete successfully even when notifications are missing
- Add appropriate logging
## Data Models
### Notification Model
No changes to the notification model structure are required. The existing polymorphic associations and dependent_notifications configuration will continue to work as designed.
### Logging Data
New log entries will be created when notifications are missing:
- Log level: WARN
- Message format: "Notification with id [ID] not found for email delivery, likely destroyed before job execution"
- Include relevant context (target, notifiable type, etc.) when available
## Error Handling
### Exception Handling Strategy
1. **Primary Exceptions**:
- **ActiveRecord**: `ActiveRecord::RecordNotFound`
- **Mongoid**: `Mongoid::Errors::DocumentNotFound`
- **Dynamoid**: `Dynamoid::Errors::RecordNotFound`
2. **Handling Approach**: Catch all ORM-specific exceptions, log appropriately, do not re-raise
3. **Fallback Behavior**: Complete job successfully, no email sent
### Error Recovery
- No automatic retry needed since the notification is intentionally destroyed
- Log warning for monitoring and debugging purposes
- Continue processing other notifications normally
### Error Logging
```ruby
# Example log message format with ORM detection
Rails.logger.warn "ActivityNotification: Notification with id #{notification_id} not found for email delivery (#{orm_name}), likely destroyed before job execution"
```
### ORM-Specific Error Handling
```ruby
# Unified exception handling for all supported ORMs
rescue_from_notification_not_found do |exception|
log_missing_notification(notification_id, exception.class.name)
end
# ORM-specific rescue blocks
rescue ActiveRecord::RecordNotFound => e
rescue Mongoid::Errors::DocumentNotFound => e
rescue Dynamoid::Errors::RecordNotFound => e
```
## Testing Strategy
### Multi-ORM Testing Requirements
All tests must pass across all three supported ORMs:
- **ActiveRecord**: `bundle exec rspec`
- **Mongoid**: `AN_ORM=mongoid bundle exec rspec`
- **Dynamoid**: `AN_ORM=dynamoid bundle exec rspec`
### Code Coverage Requirements
- **Target**: 100% code coverage using Coveralls
- **Coverage Scope**: All new code paths and exception handling logic
- **Testing Approach**: Comprehensive test coverage for all ORMs and scenarios
### Unit Tests
1. **Test Missing Notification Handling (All ORMs)**
- Create notification in each ORM
- Destroy notification using ORM-specific methods
- Attempt to send email
- Verify ORM-specific exception is caught and handled
- Verify appropriate logging occurs
- Ensure 100% coverage of exception handling paths

- Test `ActiveRecord::RecordNotFound` exception handling
- Test with ActiveRecord-specific dependent_notifications behavior
- Ensure 100% coverage of ActiveRecord code paths
- **Mongoid ORM implementation** (`AN_ORM=mongoid bundle exec rspec`)

- **Various notification types and configurations**
- **Coveralls Integration**
- Ensure all new code paths are covered by tests
- Maintain 100% code coverage requirement
- Cover all exception handling branches and logging paths
## Implementation Considerations
### Backward Compatibility
- All existing APIs remain unchanged
- No configuration changes required
- Existing error handling behavior preserved for other error types
### Performance Impact
- Minimal performance impact (only adds exception handling)
- No additional database queries in normal flow
- Logging overhead is minimal
### ORM Compatibility
The solution needs to handle different ORM-specific exceptions and behaviors:
#### ActiveRecord
- **Exception**: `ActiveRecord::RecordNotFound`
- **Behavior**: Standard Rails exception when record not found
- **Implementation**: Direct rescue block for ActiveRecord::RecordNotFound
#### Mongoid
- **Exception**: `Mongoid::Errors::DocumentNotFound`
- **Behavior**: Mongoid-specific exception for missing documents
- **Implementation**: Rescue block for Mongoid::Errors::DocumentNotFound
- **Considerations**: Mongoid may have different query behavior
#### Dynamoid
- **Exception**: `Dynamoid::Errors::RecordNotFound`
- **Behavior**: DynamoDB-specific exception for missing records
- **Implementation**: Rescue block for Dynamoid::Errors::RecordNotFound
- **Considerations**: DynamoDB eventual consistency may affect timing
#### Unified Approach
- Create a common exception handling method that works across all ORMs
- Use ActivityNotification.config.orm to detect current ORM
- Implement ORM-specific rescue blocks within a unified interface
### Configuration Options
Consider adding optional configuration for:
- Log level for missing notification warnings
- Whether to log missing notifications at all
- Custom handling callbacks for missing notifications
## Security Considerations
### Information Disclosure
- Log messages should not expose sensitive user data
- Include only necessary identifiers (notification ID, basic type info)
- Avoid logging personal information from notification parameters
### Job Queue Security
- Ensure failed jobs don't expose sensitive information
- Maintain job queue stability and prevent cascading failures
## Monitoring and Observability
### Metrics to Track
- Count of missing notification warnings
- Success rate of email jobs after implementation
- Performance impact of additional error handling
### Alerting Considerations
- High frequency of missing notifications might indicate application issues
- Monitor for patterns that suggest systematic problems
- Alert on unusual spikes in missing notification logs

# Requirements Document
## Introduction
This feature addresses a critical issue ([#50](https://github.com/simukappu/activity_notification/issues/50)) in the activity_notification gem where background email jobs fail when notifiable models are destroyed before the mailer job executes. This commonly occurs in scenarios like "Like/Unlike" actions where users quickly toggle their actions, causing the notifiable to be destroyed while the email notification job is still queued.
The current behavior results in `Couldn't find ActivityNotification::Notification with 'id'=xyz` errors in background jobs, which can cause job failures and poor user experience.
## Requirements
### Requirement 1
**User Story:** As a developer using activity_notification with dependent_notifications: :destroy, I want email jobs to handle missing notifications gracefully, so that rapid create/destroy cycles don't cause background job failures.
#### Acceptance Criteria
1. WHEN a notification is destroyed before its email job executes THEN the email job SHALL complete successfully without raising an exception
2. WHEN a notification is destroyed before its email job executes THEN the job SHALL log an appropriate warning message
3. WHEN a notification is destroyed before its email job executes THEN no email SHALL be sent for that notification
### Requirement 2
**User Story:** As a developer, I want to be able to test scenarios where notifications are destroyed before email jobs execute, so that I can verify the resilient behavior works correctly.
#### Acceptance Criteria
1. WHEN I create a test that destroys a notifiable with dependent_notifications: :destroy THEN I SHALL be able to verify that queued email jobs handle the missing notification gracefully
2. WHEN I run tests for this scenario THEN the tests SHALL pass without any exceptions being raised
3. WHEN I test the resilient behavior THEN I SHALL be able to verify that appropriate logging occurs
### Requirement 3
**User Story:** As a system administrator, I want background jobs to be resilient to data changes, so that temporary data inconsistencies don't cause system failures.
#### Acceptance Criteria
1. WHEN notifications are destroyed due to dependent_notifications configuration THEN background email jobs SHALL not fail the entire job queue
2. WHEN this resilient behavior is active THEN system monitoring SHALL show successful job completion rates
3. WHEN notifications are missing THEN the system SHALL continue processing other queued jobs normally
### Requirement 4
**User Story:** As a developer, I want the fix to be backward compatible, so that existing applications using activity_notification continue to work without changes.
#### Acceptance Criteria
1. WHEN the fix is applied THEN existing notification email functionality SHALL continue to work as before
2. WHEN notifications exist and are not destroyed THEN emails SHALL be sent normally
3. WHEN the fix is applied THEN no changes to existing API or configuration SHALL be required
