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.

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.
