Question

对于我的生活，我无法让这一切发挥作用。我已经研究了这个错误意味着什么，并且实际上只收到了接近“将MIDDLEWARE改为MIDDLEWARE_CLASSES”的响应。这没用。我已经尝试重新安排中间件类，但是，这也没有用。我的代码中有什么我应该关注的是导致此错误吗？

方法

当用户登录时，用户将被定向到.com / user /，它将根据is_userA或is_userB属性确定要显示的仪表板。但是，当我登录时，我提供的'WSGIRequest'对象没有属性'user'。

Answer 1

Exception Value: 'WSGIRequest' object has no attribute 'User'

那是因为该属性是“用户”。

Answer 2

为用户使用小写：

request.user

'WSGIRequest'对象没有属性'user'
