Use a different layout for Devise User Auth than standard template

devise_layout_override.html.erb

class ApplicationController < ActionController::Base
  layout :layout_by_resource

  def layout_by_resource
    # If user isn't signed in or is on the main devise controllers, we'll use a different layout
    if devise_controller? && resource_name == :user && action_name == 'new'
      "devise"
    else
      "application"
    end
  end
end
