How to skip layout with devise?

Question

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  layout :check_layout

  def check_layout
    return nil if request.xhr?
    'application'
  end
end

Devise ignores this condition and renders layout. How to fix?

// upd

Now trying in config/application.rb - still ignores for sign_in and sign_up ;(

config.to_prepare do
  Devise::SessionsController.layout nil
  Devise::RegistrationsController.layout nil
end

Answer 1

Use layout false to render no layout.

layout nil will force default layout behavior with inheritance.
