rails 3, how add a view that does not use same layout as rest of app?

Question

I could not find any docs or examples on how to structure my app to allow different views in the same controller to use completely different layouts and stylesheets.

I am sure there's plenty of answers to this but here's another one where you can use different layouts per controllers or per action.

class ListingsController < ApplicationController
  # every action will use the layout template app/views/layouts/listing_single.html.erb
  layout 'listing_single'
  # the 'list' action will use the layout set in the 'alternative_layout' method
  # you can also add multiple actions to use a different layout,just do like layout :alternative_layout, only: [:list,:another_action]
  layout :alternative_layout, :only => :list

   def show
   end   

   def list
   end

   private
   def alternative_layout
    if current_user.is_super_admin?
       #if current use is super admin then use the layout found in app/views/layouts/admin.html.erb otherwise use the layout template in app/views/layouts/listing_list.html.erb
      'admin'
    else
      'listing_list'
    end
  end
end
