Robby on Rails: Where did my observer go?

Where did my observer go?

Robby Russell — Mon, 27 Feb 2006 23:05:00 -0600

I was playing around with an application from script/console and all of a sudden… my Observers just stopped working. It took me a while to figure out that when I would call Dispatcher.reset_application!... it wouldn’t reload config/environment.rb where I have defined the observers.

I really don’t like that this is the current implementation for invoking Observers and adding them to the controllers is not kosher with my (do-it-in-script-console) approach.

The current solution?


# app/models/foo_bar.rb
class FooBar < ActiveRecord::Base
end

FooBarObserver.instance

... there needs to be a better way!

Michael,

That assumes that your application is always engaged through your controllers. If you have a script that engages your models… do you not want your observers to still work?

Sorry for the late response:

I thought that was placed in the controller class.

For example, FooController has a line at the top of the class stating:

  observer :foo_bar_observer

Michael,

Do you mean in config/environment.rb?

Yes, you do… but if you are in script/console and run Dispatcher.reset_application! it doesn’t reload your Observers.

Robby – I thought that you invoked Observers in rails as follows:

observer :foo_bar_observer
