我创建了一个模型 CustomerRegistration 并在其中添加了字段,我与用户模型建立了关系并将其注册到 admin.py 文件中。当我转到 Django 默认管理面板并注册客户时,它给出了一个错误。'''TypeError at /admin/customer/customerregistration/add/ str返回了非字符串(用户类型)'''。我不知道出了什么问题。
这是我的模型.py
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin
from django.db import models
from django.utils import timezone
# Create Your Models Here.
class UserManager(BaseUserManager):
def _create_user(self, username, password, is_staff, is_superuser, **extra_fields):
if not username:
raise ValueError('Users must have an username address')
now = timezone.now()
username = self.model.normalize_username(username)
user = self.model(
username=username,
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, username=None, password=None, **extra_fields):
return self._create_user( username, password, False, False, **extra_fields)
def create_superuser(self, username, password, **extra_fields):
user = self._create_user(username, password, True, True, **extra_fields)
user.save(using=self._db)
return user
class User(AbstractBaseUser, PermissionsMixin):
username = models.CharField(max_length=254,unique=True)
name = models.CharField(max_length=254, null=True)
email = models.EmailField(max_length=254, null=True)
is_staff = models.BooleanField(default=False)
is_superuser = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
is_service = models.BooleanField(default=False)
is_customer = models.BooleanField(default=False)
is_admin = models.BooleanField(default=False)
