Rails - Jun 2006 - Observable notifying a controller.

I want to code the following task:

I have a class, for instance, class A with is a observable.

I want to add a controller of my rails system to this class. So I can 
notify_observer, and it updates all controllers of my system.

How do I pass a controller as a parameter to the add_observer() method? 
And where I put this code?

Thanks in advance.

To develop a chat application I have a external class that notify every 
user in the chat about a new conversation.
I''m using observer pattern. Now, I want to create a controller in my 
rails app. And notify this controller to change the view when it 
receives a new action.

How could I implement this?

I need to pass a instance of my classto the controller initialize method.

def initialize(observable)
    observable.add_observer(self)
end

Where I initialize this instance of my class?

Thanks in advance.
