Where did my observer go?

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!

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

    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,

    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?
