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.
