If you have a controller that uses a general layout, but you want to use a custom layout for one of your controller methods and the corresponding view, what you do is simply to add a render :layout => ‘my_layout’ to the method. Have a look at the below example:

class MyController < ApplicationController
layout ‘main’

 def my_method

   # Do stuff here…
   render :layout => ‘my_layout’

 end

end
