如何在Devise中自动保留用户的记忆

问题描述

我正在构建一个应用程序，其中我希望用户在他们的电脑上自动记住，而没有记住我复选框。

我阅读我可能必须调用 @ user.remember_me！，但不知道从Devise控制器隐藏起来的位置。

我正在考虑在sign_in表单中添加一个隐藏的复选框字段，其中复选框被标记为默认值，但我希望我可以在控制器端执行此操作。

任何想法如何做？

谢谢！

解决方案

我认为定制你的设计控制器是去这里的方式。

目标：为每个人自动设置记住。

首先，创建一个设计会话控制器。让我们告诉铁路线路

config / routes.rb

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

app / controllers / sessions_controller.rb

  class SessionsController< Devise :: SessionsController 
 
 def create 
 params [：user] .merge！（remember_me：1）
 super 
 end 
 
 end 
  

这样，用户记住我将永远设置为true。你可以编辑登录表单以显示remember_me复选框。

另外，将初始化器中的这个更改为远离的位置：

 ＃config.remember_for = 2.weeks 
 config.remember_for = 1年
  

I am building an app in which I would like the users to automatically be remembered on their computers, without having a "remember me" check box.

I read that I may have to call @user.remember_me!, but not sure where to call it since the Devise controllers are hidden.

I was considering adding a hidden checkbox field in the sign_in form with the checkbox marked by default, but I was hoping I could do this on the controllers side.

Any idea how this could be done?

Thanks!

解决方案

I think customizing your devise controller is the way to go here.

Goal: automatically set remember-me for everybody.

First, create a devise sessions controller. Let's tell rails routes about it

config/routes.rb

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

app/controllers/sessions_controller.rb

class SessionsController < Devise::SessionsController

  def create
    params[:user].merge!(remember_me: 1)
    super
  end

end

This way, the user's remember me will always be set to true. yay!

You'll then want to edit the login form to not display the remember_me checkbox.

Also, change this in the initializer to something far off:

#config.remember_for = 2.weeks
config.remember_for = 1.year
