将Devise与Ruby on Rails一起使用，如果用户使用无效的auth_token，如何将用户发送到sign_in路径？

[英]Using Devise with Ruby on Rails, how can I send the user to sign_in path if they use an invalid auth_token?

原文 2012-10-25 14:49:09 3 1 ruby-on-rails/ devise

When I send a user to /dashboard?auth_token=XXX , and the auth_token is incorrect, the user gets taken to the root_path . 当我将用户发送到/dashboard?auth_token=XXX ，并且auth_token不正确时，用户将被带到root_path 。

In this situation, I want the user to be taken to the sign_in path, and then be taken to /dashboard after they sign in. How can I do this? 在这种情况下，我希望用户被带到sign_in路径，然后在他们登录后被带到/dashboard 。我该怎么做？

1 个解决方案

The default in Devise is to redirect to "new_#{scope}_session_path" route if one is available. Devise中的默认值是重定向到“new _＃{scope} _session_path”路由（如果有）。 As seen here: 如下所示：

https://github.com/plataformatec/devise/blob/master/lib/devise/failure_app.rb#L89 https://github.com/plataformatec/devise/blob/master/lib/devise/failure_app.rb#L89

So, assuming you are using the user scope, be sure you have a new_user_session_path defined by your router. 因此，假设您使用的是用户范围，请确保路由器已定义new_user_session_path 。

About redirecting back to the original page, try out this wiki page: 关于重定向回原始页面，请试用此Wiki页面：

https://github.com/plataformatec/devise/wiki/How-To:-Redirect-back-to-current-page-after-sign-in https://github.com/plataformatec/devise/wiki/How-To:-Redirect-back-to-current-page-after-sign-in

Notice the filter in the wiki page needs to be added before you invoke Devise's authentication filters. 请注意，在调用Devise的身份验证过滤器之前，需要添加Wiki页面中的过滤器。
