BroadcastPolicy

This allows us to do something like:

class Model < ActiveRecord::Base has_a_broadcast_policy

set_broadcast_policy do |p| p.dispatch :notification_name p.to { some_endpoints } p.whenever { |record| record.foo_is_true? && record.bar_is_false? } p.data { course_id: course_id, root_account_id: root_account_id} end

end

Usage

In order to use the gem in Rails, you'll need an initializer something like this:

config/initializers/broadcast_policy.rb

require 'broadcast_policy' Rails.configuration.to_prepare do BroadcastPolicy.notifier = lambda { Notifier.new } BroadcastPolicy.notification_finder = lambda { NotificationFinder.new(Notification.all_cached) } end ActiveRecord::Base.send(:extend, BroadcastPolicy::ClassMethods)

The two BroadcastPolicy services are necessary to supply the canvas domain objects for integrating with the notification system License
