Because you're treating #a_method as a class method when it is an instance method.

Put #a_method into app/controllers/application.rb instead. This file defines the class ApplicationController which your other controllers inherit from, so this will make the method available in all controllers.

Mark is right and the other option you have is use mixin ie create a module, put your a_method in it and include that module in both controller classes. This will make your a_method available in both controllers or in any controller in which you include that module.
