Django自定義登錄模型錯誤

Question

你好，我試圖讓Django的自定義用戶模型，但我得到以下錯誤。 -

ERRORS：

auth.User.groups：（fields.E304）關於 'User.groups' 衝突與關於 'Freelancer.groups' 反向存取反向存取。 提示：爲'User.groups'或'Freelancer.groups'的定義添加或更改related_name參數。 auth.User.user_permissions： （fields.E304）'User.user_permissions'的反向訪問者爲'Freelancer.user_permissions'與反向訪問者衝突 。 提示：爲'User.user_permissions'或'Freelancer.user_permissions'的定義添加或更改related_name參數。 login.Freelancer.groups：（fields.E304）反向訪問者 'Freelancer.groups'與'User.groups'的反向訪問者衝突。 提示：爲'Freelancer.groups'或'User.groups'的定義添加或更改related_name參數。 login.Freelancer.groups： （fields.E331）字段通過模型 'login.Freelancer_groups'指定了一個多對多關係，該關係尚未安裝。 login.Freelancer.user_permissions：（fields.E304）反向訪問者 'Freelancer.user_permissions'與反向訪問者衝突 'User.user_permissions'。 提示：爲'Freelancer.user_permissions'或'User.user_permissions'的定義添加或更改related_name參數。 login.Freelancer.user_permissions：（fields.E331）字段通過 'login.Freelancer_user_permissions'指定 多對多關係，該關係尚未安裝。

Answer 1

您需要設置AUTH_USER_MODEL設置爲指向你的自由職業者階層，所以Django知道不加載默認的用戶模型。

此外，對於自由職業者來說，OneToOne對用戶沒有任何意義;這是該型號的替換件。

Answer 2

只是從你的整個代碼

from django.contrib.auth.models import User 

刪除下面一行，並嘗試導入自定義的usermodel
