In my RoR3 application I have a namespace called NS1 so that I have this filesystem structure:

ROOT_RAILS/controllers/
ROOT_RAILS/controllers/application_controller.rb
ROOT_RAILS/controllers/ns/
ROOT_RAILS/controllers/ns/ns_controller.rb
ROOT_RAILS/controllers/ns/names_controller.rb
ROOT_RAILS/controllers/ns/surnames_controller.rb

I wuold like that 'ns_controller.rb' inherits from application controller, so in 'ns_controller.rb' file I have:

class Ns::NsController < ApplicationController
  ...
end

Is this the right approach? Anyway if I have this situation...

in 'application_controller.rb'

class ApplicationController < ActionController::Base
  @profile = Profile.find(1)
end

in 'ns_controller.rb'

class Ns::NsController < ApplicationController
  @name = @profile.name
  @surname = @profile.surname
end

... '@name' and '@surname' variables are not set. Why?
