I’ve seen two ways of connecting observers:
-
In the observer class put
observe MyModel
-
In the controller class put
observer :my_observer
What is the difference between these two? Also, is it necessary to put
in the observer class the following?
MyObserver.instance

Don’t go the controller route… that doesn’t really work when you’re
doing stuff that isn’t through your controllers.
I posted about this a while back on my blog:
http://www.robbyonrails.com/articles/2006/02/27/where-did-my-observer-go
You can do the following:
- create the observer:
app/models/custom_observer.rb
class CustomObserver < ActiveRecord::Observer
showing how you can use Camel or symbols
observe Contact, :contact_note
def after_create( object )
# do something… with object
end
end
- Modify config/environment.rb
config.active_record.observers = :custom_observer
- have fun!
Hope that helps!
