them: what would normally be users_path becomes admin_users_path, and new
_user_path becomes new_admin_user_path.
With this namespace defined, when you run bin/rspec spec/controllers/admin
/users_controller_spec.rb, you should see it fail with a different error:
Failure/Error: response.should redirect_to(root_path)
Expected response to be a , but was
This error appears because you need to implement the authorize_admin
!before_filter for your namespace. To apply it to all controllers in this namespace,
you create a new supercontroller whose only job (for now) is to call the before_filter.
You can also put methods that are common to the admin section here.
Create a new file at app/controllers/admin/base_controller.rb, and fill it with this
code:
class Admin::BaseController < ApplicationController
before_filter :authorize_admin!
end
This file can double as an eventual homepage for the admin namespace and as a class
that the other controllers inside the admin namespace can inherit from, which you’ll
see in a moment. You inherit from ApplicationController with this controller so you
receive all the benefits it provides, like the authorize_admin! method and the Action
Controller functionality.
Open app/controllers/admin/users_controller.rb, and change the first line of the
controller from this
class Admin::UsersController < ApplicationController
to this:
class Admin::UsersController < Admin::BaseController
Because Admin::UsersController inherits from Admin::BaseController, the
before_filter from Admin::BaseController now runs for every action inside
Admin::UsersController, and therefore in your spec, should pass.
Run it with bin/rspec spec/controllers/admin/users_controller_spec.rb
now, and you should see this:
.

With that done, you should ensure that everything is working as expected by running
rake cucumber:ok spec:
25 scenarios (25 passed)
200 steps (200 passed)

Great, everything is still green! Let’s commit that:
