I have the answer for the Rails 2.X but not for Rails 3. How can I read the name of a current layout rendered inside a view.

My Rails2 question: Rails Layout name inside view

For rails 5:

controller.class.send(:_layout)

This does NOT work:

controller.send(:_layout)
user_3282940

All the approaches in the previous answers try to guess the name via private methods, but there's no need to guess and can be easily accomplished with the public API:

class ApplicationController
  layout :set_layout
  attr_reader :layout_name
  helper_method :layout_name

  private

  def set_layout
    @layout_name = "application"
  end
end

Override in any controller that won't use the standard layout:

class MyController < ApplicationController
  private

  def set_layout
    @layout_name = "my_layout"
  end
end

And now in your views:

<%= layout_name %>
