如何通过电子邮件对用户进行身份验证? [英] How to authenticate the user from the email?

问题描述

我有一个使用devise进行身份验证的Rails应用程序.当应用程序向用户发送任何通知时，为了查看通知或消息，我提供了指向我的Rails应用程序的链接，该链接重定向到登录页面.

I have a rails application which uses devise for authentication. when the application sends any notification to the user, then in order to see the notification or messages i provide a link to my rails application which redirects to a login page.

我如何避免此登录过程，这意味着我不希望通过输入电子邮件和密码来要求用户登录，而是每当用户单击该链接时，用户都应自动登录.

how can i avoid this login process, means i don't want the user to be asked to login by entering email and password, instead whenever the user clicks on that link, then the user should automatically login.

推荐答案

Devise提供了sign_in控制器帮助器，该帮助器允许您以编程方式通过身份验证.

Devise provides sign_in controller helper which allows you to pass authentication programmatically.

sign_in(user)
