Ruby on rails 用户登录身份验证在RubyonRails中不起作用

我正在尝试通过登录页面将用户登录到我的rails站点。“我的用户”输入他们的电子邮件和密码以便登录，但当他们单击“提交”按钮时，页面会自动刷新-但它应该会将用户带到他们的仪表板（用户配置文件屏幕）

我似乎不知道为什么。虽然我从数据库中得到的信息如下：

user.authenticate方法的作用是什么？似乎条件块在

User.authenticate

条件下失败。我认为正确的身份验证是问题所在。你能在你的用户模型中通过吗？@Cyzanfar看到上面粘贴的User.rb:）你的实例方法

authenticate

在你的用户模型中声明在哪里？@Cyzanfar啊，也许这就是我缺少的。我觉得我的user.rb文件就是这么做的。刚刚在上面粘贴了我的用户_controller.rb。PS-为我的新问题道歉；我还在试着绕着栏杆转！
