导轨和设计:如何在没有布局的情况下呈现登录页面? [英] Rails & Devise: How to render login page without a layout?

问题描述

我知道这可能是一个简单的问题，但我仍在尝试设计...

I know this is probably a simple question, but I'm still trying to figure Devise out...

我想 render :layout =>false 在我的登录页面上；我怎样才能用 Devise 做到这一点?

I want to render :layout => false on my login page; how can I do this with Devise?

推荐答案

您可以子类化控制器并配置路由器以使用它:

You can subclass the controller and configure the router to use that:

class SessionsController < Devise::SessionsController
  layout false
end

在 config/routes.rb 中:

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

您也需要将会话视图移动到此控制器.

You need to move the session views to this controller too.

OR 在 app/controllers/application_controller.rb 中创建一个方法:

OR make a method in app/controllers/application_controller.rb:

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
