Namespaced ApplicationController in Rails

I have my regular ApplicationController class & I have a Admin::ApplicationController class. The problem is that Admin::ApplicationController doesn't seem to be getting loaded or executed or anything. Am I not allowed to have a namespaced application controller? The reasoning for wanting to have it is so that I can check if a user is an admin w/ CanCan & redi开发者_如何学编程rect them out if they're not.

Call this controller Admin::BaseController, as it is more to act as the base of the namespace than to do anything for the appilcation. For it to do what you want to do, you will need to make all admin namespaced controllers inherit from this controller.

The only times I've seen namespacing like that is when the controller is nested in a subfolder. So Admin::ApplicationController would expect to be in controllers/admin/application_controller.rb

One possible solution:

If you want everything except your home page to kick them out, simply set a before_filter on your application controller with an exception for home/index like this:

ApplicationController.rb

before_filter :authorize_admin

def authorize_admin
   //dostuff
end

HomeController.rb

skip_before_filter :authorize_admin, :only => ['index']

Where index is your action that you want to skip. Leave off the only to skip the filter for the whole controller.
