Rendering Layout for specific actions

Here I've a controller with 4 actions and i wanna apply application layout ( the default layout ) to new action only , or in other words i wanna except only index action from the layout so i write this but it doesn't work, the index template is rendering with the layout. 

class SessionsController < ApplicationController

    layout 'application', :except => :index

    def index
    end 

    def new
    end


    def create
        end
    end

    def destroy
    end

end

also I tried 

layout 'application', :only => :new

but it doesn't work too, same problem which the index template is rendering with layout. any suggestions what's the problem here?

Here's code that you can use in your controllers:

layout :resolve_layout
...
...

private

def resolve_layout
  if %w(index show).include?(action_name)
    "application"
  elsif %w(show).include?(action_name)
    "admin"
  else
    "generic"
end

Basically, treat those arrays as your :only statements for layout that you are giving them if they are evaluated as true when compared with current action_name.

EDIT: I forgot to mention that this allows :only, :except, etc.

You can create a method to define your layout and fix your layout only on new action 

layout :my_layout

def my_layout
  params[:action] == 'new' ? 'application' : nil
end
