Create your custom controller for CanCan to skip_authorization_check

issue01

rails version: 3.2.9
ruby 1.9.3p125 (2012-02-16 revision 34643) 
devise 2.2.3
[i686-linux]
OS: Debian Linux Lenny(I know... gonna update to Squeeze)
Listening to: http://www.youtube.com/watch?v=ab5hLh_Nurg&feature=share&list=RD02EXf5tcjdO8s while programming :)

Controller:
class Guards::SessionsController < Devise::SessionsController
  before_filter :authenticate_admin!
  load_and_authorize_resource
  skip_authorization_check :only => [:index]
end
saved as: controllers/guards/sessions_controller.rb


routes.rb
Api::Application.routes.draw do
authenticated :admin do
    root :to => 'admins#index'
  end
  root :to => "reception#index"
  devise_for :admins, :controllers => {:sessions => "guards/sessions"}
end

*ERRORS I'm getting:
When devise rects to sign in on my browser it says:
http://postimg.org/image/p0zzt40b7/ 
(an image worth a thousand words)



output from the live shell:
