在生产模式中无意中破坏了Rails Devise会话

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在生产模式中无意中破坏了Rails Devise会话相关的知识，希望对你有一定的参考价值。

在生产模式下成功登录我的Rails应用程序后，我将尝试单击表顶部的过滤器按钮之一：“所有服务器”，“进行中”或“修复”。 按下其中一个按钮后，会话将被破坏，并将用户重定向回登录页面； 但是，这在开发环境中不会发生 。 在开发环境中，当用户按下过滤器按钮之一时，将应用适当的范围，并且不会发生重定向。

在将生产日志与开发日志进行比较之后，该错误似乎出现在Devise::SessionsController#new

可以在以下位置找到源代码： https ： //github.com/herman5/warthog

我将应用程序托管在Heroku上，因此可以看到效果。

网址 ： http ： //testdomain.dcmdashboard.com

电子邮件 ：moderator@example.com

密码 ：密码

登录并在开发环境中按下过滤器按钮（ GET "/?order=id_desc&page=1&scope=in_progress" ）后：

答案

在试用了托管版本之后，我认为问题出在用于对服务器表进行排序的链接中。 当前，您使用链接http://testdomain.dcmdashboard.com/?order=operating_system_desc来按操作系统对表进行排序。 如果您改用http://testdomain.dcmdashboard.com/admin/?order=operating_system_desc （在查询参数前面使用/ admin /），则会话不会被杀死，也不必再次登录。

仅在app/admin/servers.rb具有您自己定义的集合的那些列确实存在此问题。 它可能是active_admin当前开发版本中的错误或缺少参数。

请在config/initializers/active_admin.rb为默认名称空间添加一个值： 

config.default_namespace = :admin

如果问题仍然存在，请尝试使用active_admin的稳定版本（如0.6.2版），然后重试。

另一答案

生产与开发之间的唯一区别是，当您跟踪使您退出/ admin名称空间的链接时，生产会将您注销，这两种情况都存在问题，它看起来像是ActiveAdmin错误。

与主动管理中的好人保持联系将有助于https://github.com/gregbell/active_admin/issues/2839

另外，虽然将ActiveAdmin用于非常简单的应用程序，并且脚手架很好并且可以，但是您会感到沮丧，因为您决定使用它进行任何复杂的工作，而在失去修复这一范围的时间中，您可能可以使用ransack和设计

以上是关于在生产模式中无意中破坏了Rails Devise会话的主要内容，如果未能解决你的问题，请参考以下文章
