AbstractUser无法使用Django！ （替换自定义用户模型）

Question

应用名称为“后端”

Models.py

from django.db import models
from django.contrib.auth.models import User
from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
    fb_userid = models.CharField(max_length=256)

Settings.py

AUTH_USER_MODEL = 'backend.User'

INSTALLED_APPS = [
    'backend.apps.BackendConfig',
    'rest_framework',
    'rest_framework.authtoken',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'oauth2_provider',
    'bffcode',
]

错误：

我正在尝试在项目中替换用户模型，但无法创建迁移

Answer 1

我同意丹尼尔（Daniel）不导入用户的观点，但是即使您要更改为自定义用户模型的中间项目，由于Django对可交换模型的动态依赖功能的局限性，仍然存在后果，

AUTH_USER_MODEL引用的模型必须在其应用程序的首次迁移中创建（通常称为0001_initial）； 否则，您将遇到依赖性问题。
