我创建了一个自定义用户模型，并尝试创建一个新用户。我在shell中尝试了manage.py createsuperuser以及我的代码中的User.objects.create_user(email, password)。两者都会导致相同的错误：
$ ./manage.py createsuperuser
Email: person@example.com
Is manager: True
Password:
Password (again):
Traceback (most recent call last):

我的模特/经理：
class UserManager(BaseUserManager):
def create_user(self, email, password, **kwargs):
if not email:
raise ValueError('Users must have an email address')
user = self.model(self.normalize_email(email), **kwargs)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, password, **kwargs):
user = self.create_user(email, password, **kwargs)
user.is_admin = True
user.save(using=self._db)
return user
class User(AbstractBaseUser, PermissionsMixin, EditMixin):
email = models.EmailField(max_length=255, unique=True)
business_access = models.ManyToManyField(BusinessAccess, blank=True)
auth_key = models.UUIDField(unique=True, max_length=64, default=uuid.uuid4)
is_manager = models.BooleanField(default=False)
REQUIRED_FIELDS = ['is_manager']
USERNAME_FIELD = 'email'
objects = UserManager()
class Meta:
verbose_name = "User"
verbose_name_plural = "Users"
def __str__(self):
return self.email
def get_full_name(self):
return self.email
def get_short_name(self):
return self.email
@property
def is_staff(self):
return self.is_superuser
我做错了吗？
答案 0 :(得分：0)
尝试使用Manager
中的create_user方法def _create_user(self, email, password,
is_staff, is_superuser, **extra_fields):
"""
Creates and saves a User with the given email and password.
"""
now = timezone.now()
if not email:
raise ValueError('The given email must be set')
email = self.normalize_email(email)
user = self.model(email=email,
is_staff=is_staff, is_active=True,
is_superuser=is_superuser, last_login=now,
date_joined=now, **extra_fields)
user.set_password(password)
user.save(using=self._db)
return user
def create_user(self, email, password=None, **extra_fields):
return self._create_user(email, password, False, False,
**extra_fields)
def create_superuser(self, email, password, **extra_fields):
return self._create_user(email, password, True, True,
**extra_fields)
我尝试了你的例子并遇到了同样的错误。这是我的实现，没有任何问题正确工作

您需要写信，这对我有帮助：
self.model(email=self.normalize_email(email), **kwargs)
