rails gem devise登录页不render layout 方法

方法1:

  class SessionsController < Devise::SessionsController 
      layout false
  end

修改config/routes.rb

devise_for :users, :controllers => { :sessions => "sessions" }

同时把session views 移到这个controller下

方法2:

class ApplicationController < ActionController::Base 
  layout :layout 
  private 
  def layout 
    # only turn it off for login pages:
     is_a?(Devise::SessionsController) ? false : "application" 
    # or turn layout off for every devise 
      controller: devise_controller? && "application" 
  end
end
