Question

我有一个用于登录，忘记密码和更改个人资料信息的用户身份验证系统，但我的登出路线对我来说很古怪并且给我错误The action 'destroy' could not be found for PagesController。我不知道为什么它会调用PagesController。我有一个用于管理操作的命名空间PagesController和一个仅用于show方法的页面控制器。就像我说的，除了会话注销外，一切都很完美。谢谢。

Answer 1

试试这个，

delete '/logout', to: 'sessions#destroy'

并使用

重新检查您的路线

rake routes | grep logout

希望有所帮助

Answer 2

您可以将method get更改为delete

delete '/logout', to: 'sessions#destroy'
