Question

我已经自定义我的用户模型。我在用户模型中添加了许多其他字段。当我尝试通过单击Django管理面板上的“添加用户”按钮来添加用户时，发生以下错误。以及如何自定义此“添加用户”部分。我想在这里添加更多字段。 Imgur

IntegrityError at /admin/accounts/user/add/
duplicate key value violates unique constraint "accounts_user_email_key"
DETAIL:  Key (email)=() already exists.

我正在使用django2.2，目前正在django中学习复杂的东西。我已经自定义了用户模型。当我尝试通过在django的管理面板中单击此“添加用户”来添加用户时，会发生此错误。

这是我的代码。

class UserManager(BaseUserManager):
     def create_user(self, username, email, firstname, lastname, profile_photo,mobile_phone_number, password=None, is_staff=False, is_active=True, is_admin=False, is_moderator=False):

        if not firstname:
            raise ValueError("User must have an Firstname")            
        if not lastname:
            raise ValueError("User must have an Lastname")

        user_obj = self.model(username = username,
                                email = email)
        user_obj.set_password(password)
        user_obj.email = email
        user_obj.firstname = firstname
        user_obj.lastname = lastname

我试图找到解决方案，但没有找到解决办法。

如何修复重复的键值违反了唯一约束并在Django管理面板中自定义“添加用户”部分？
