我正在尝试创建用于身份验证的自定义用户模型。我做的一切都和Django文档中的一样，但当我试图用命令行创建超级用户时，我得到了错误。我试图删除数据库和迁移，然后再次运行它们，但没有帮助。
这是我的型号。py
from django.db import models
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManager
from django.db.models.deletion import CASCADE
from django.utils import timezone
from django.utils.translation import gettext_lazy
# Create your models here.
class UserAccountManager(BaseUserManager):
def create_user(self, Email, Name, Surname, Password = None, **other_fields):
if not Email:
raise ValueError(gettext_lazy('You must provide email address'))
email = self.normalize_email(Email)
user = self.model(email, Name, Surname, **other_fields)
user.set_password(Password)
user.save(using=self._db)
return user
def create_superuser(self, Email, Name, Surname, Password = None, **other_fields):
other_fields.setdefault('is_staff', True)
other_fields.setdefault('is_superuser', True)
other_fields.setdefault('is_active', True)
return self.create_user(Email=Email, Name = Name, Surname = Surname, Password = Password, **other_fields)
class Customer(AbstractBaseUser, PermissionsMixin):
Email = models.EmailField(gettext_lazy('email address'), max_length=256, unique=True)
Name = models.CharField(max_length=64)
Surname = models.CharField(max_length=64, null=True)
Birthday = models.DateField(auto_now=False, null=False,blank=True)
PhoneNumber = models.CharField(max_length=16, unique=True, blank=True)
Address = models.CharField(max_length=128, blank=True)
RegistrationDate = models.DateTimeField(default=timezone.now, editable=False)
is_staff = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
is_superuser = models.BooleanField(default=False)
objects = UserAccountManager()
USERNAME_FIELD = 'Email'
REQUIRED_FIELDS = ['Name', 'Surname']
def __str__(self):
return self.Name + " " + self.Surname
def has_perm(self, perm, obj = None):
return self.is_superuser
这是我的管理员。py

user.set_password(self.cleaned_data["password1"])

在您的create_user方法中，您编写self.model(email, Name, Surname, **other_fields)，在这里您将email、Name和Surname作为位置参数传递，这就是您收到错误的原因(基本上，电子邮件被作为id字段，您传递的参数实际上会转到其他一些字段左右(。相反，将这些作为关键字参数传递。所以你的create_user方法是：
def create_user(self, Email, Name, Surname, Password = None, **other_fields):
# Your other code
user = self.model(Email=email, Name=Name, Surname=Surname, **other_fields)
# Your other code
注意：根据惯例，python中的变量名应该在
snake_case中。所以应该是CCD_ 8而不是CCD_ 9，等等。参见PEP8——Python样式指南代码
