在 Django (django-rest-framework) 中创建超级用户时出现致命错误

Question

我想创建一个没有用户名字段的 AbstractUser，所以我得到了这个：

from django.db import models
from django.contrib.auth.models import AbstractUser
from django.core.validators import RegexValidator

class CustomUser(AbstractUser):
    email = models.EmailField(max_length=254, unique=True)
    username = None

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []
    
    session_token = models.CharField(max_length=10, default=0)

    #Newsletter/Shipment Info (not required)
    newsletter = models.BooleanField(default=False)

    first_name = models.CharField(max_length=35, blank=True, null=True)
    last_name = models.CharField(max_length=35, blank=True, null=True)
    adress = models.CharField(max_length=50, blank=True, null=True)
    city = models.CharField(max_length=50, blank=True, null=True)
    postal_code = models.CharField(max_length=6, blank=True, null=True)
    phone = models.CharField(max_length=9, validators=[RegexValidator(r'^\d{9}$/')], blank=True, null=True)

    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

我已将其迁移到数据库中，现在我需要创建一个管理员用户，这样我才能进入管理面板。我在 python manage.py createsuperuser 之后在命令提示符中输入了电子邮件和两个密码，但出现了这个错误：

Traceback (most recent call last):
  File "C:\Users\mateu\Documents\meadow\backend\manage.py", line 22, in <module>

    self.UserModel._default_manager.db_manager(database).create_superuser(**user_data)
TypeError: create_superuser() missing 1 required positional argument: 'username'

我不知道如何修复它。有什么想法吗？

您必须从 AbstractBaseUser 而不是 AbstractUser 继承并向其添加 Manager Class

from django.contrib.auth.base_user import AbstractBaseUser
from django.contrib.auth.models import PermissionsMixin


class CustomUser(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(max_length=255, unique=True)
    is_superuser = models.BooleanField(default=False)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    # Add other fields here

    objects = UserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []



class UserManager(BaseUserManager):
    
    def _create_user(self, email, password, **extra_fields):
        user = self.model(email=self.normalize_email(email), **extra_fields)
        user.set_password(password)        
        user.save(using=self._db)
        return user

    def create_user(self, email, password, **extra_fields):
        return self._create_user(email, password, **extra_fields)

    def create_superuser(self, email, password, **extra_fields):
        extra_fields.setdefault('is_staff', True)
        extra_fields.setdefault('is_superuser', True)
        return self._create_user(email, password, **extra_fields)

别忘了

python manage.py makemigrations

python manage.py migrate
