如何在django中创建一些没有密码的用户组？

from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin
from django.db import models

class UserGroup(models.Model):
    name = models.CharField(max_length=255, unique=True)

    def __str__(self):
        return self.name

from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin
from django.db import models

class UserManager(BaseUserManager):
    def create_user(self, email, password=None, **extra_fields):
        # 创建用户的逻辑

class User(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(unique=True)
    user_group = models.ForeignKey(UserGroup, on_delete=models.CASCADE)

    # 其他用户模型的字段和方法

    objects = UserManager()

    USERNAME_FIELD = 'email'

python manage.py makemigrations
python manage.py migrate

from your_app.models import UserGroup

group = UserGroup(name='Group Name')
group.save()
