How to get parent's controller_name?

Question

I'm using controller.controller_name to see where I'm at, and set the active class on my menu.

The problem is I have a namespace: :admin in my routes... and I need to check if I'm in any controller which inherits from AdminController. Right now, controller_name only pulls up the child controller's name... but really I need it to say 'admin'.

How can I access the name of the controller it's inheriting from?

Answer 1

Try controller.ancestors.include?(AdminController)

Answer 2

If I'm understanding your question correctly, you could do:

controller.class.superclass

This should return AdminController if your current controller is indeed inheriting from AdminController.

Also, controller.class should give you the fully namespaced controller name.

Answer 3

Just use parent:

controller.class.parent
