Rails 3 Observer -- looking to learn how to implement an Observer for multiple models
Rails observers are sweet, You can observe multiple models within a single observer
First, you need to generate your observer:
rails g observer AuditorThen, in your fresh auditor_observer.rb file define the models you wish to observe and then add the after_create callback.
class AuditorObserver < ActiveRecord::Observer observe :model_foo, :model_bar, :model_baz def after_create(record) #do something with `record` end end In application.rb add
config.active_record.observers = :auditor_observerAnd It should work.
