'WSGIRequest'對象沒有屬性'user'

Question

我對於我的生活無法得到這個工作。我已經研究了這個錯誤意味着什麼，並且確實只收到了「更改MIDDLEWARE到MIDDLEWARE_CLASSES」的響應。這沒有奏效。我嘗試重新安排中間件類，但是，這也不起作用。我的代碼中是否有任何內容應該引起關注，導致此錯誤？

方法：

當中，用戶被引導用戶登錄到的.com /用戶/這將決定於顯示基於is_userA或is_userB屬性，該屬性信息顯示板。但是，當我登錄時，即時消息呈現的'WSGIRequest'對象沒有屬性'user'。

Answer 1

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

這是因爲屬性是 「用戶」。

Answer 2

使用小寫用戶：

request.user
