Module ActiveRecord::Observing::ClassMethods
In: lib/active_record/observer.rb

Methods

Public Instance methods

Instantiate the global Active Record observers.

Gets the current observers.

Activates the observers assigned. Examples:

  # Calls PersonObserver.instance
  ActiveRecord::Base.observers = :person_observer

  # Calls Cacher.instance and GarbageCollector.instance
  ActiveRecord::Base.observers = :cacher, :garbage_collector

  # Same as above, just using explicit class references
  ActiveRecord::Base.observers = Cacher, GarbageCollector

Note: Setting this does not instantiate the observers yet. instantiate_observers is called during startup, and before each development request.

Protected Instance methods

Notify observers when the observed class is subclassed.
