如何在django中通过自定义用户模型创建多种类型的用户？

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

class CustomUser(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(unique=True)
    username = models.CharField(max_length=30, unique=True)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)

    # 添加额外的字段
    # ...

    # 定义必需的字段
    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']

    # 添加额外的方法
    # ...

AUTH_USER_MODEL = 'accounts.CustomUser'

python manage.py makemigrations
python manage.py migrate

from django.contrib.auth import get_user_model

User = get_user_model()

# 创建普通用户
user = User.objects.create_user(email='user@example.com', username='user', password='password')

# 创建管理员用户
admin = User.objects.create_superuser(email='admin@example.com', username='admin', password='password')
