Question

希望您一切都好。从几个小时前开始，我在扩展Django的“用户”模型时出错，目的是为不同的用户添加一些字段。

要扩展模型，我依靠两个主要来源：

Github上的Django存储库-https://github.com/django/django/blob/master/django/contrib/auth/models.py

和来自博客的-simpleisbetterthancomplex-https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html#abstractbaseuser

Django版本= 2.1

在运行命令- python manage.py makemigrations 时，出现以下错误：

“ AUTH_USER_MODEL指的是尚未安装的模型'％s'”％设置。AUTH_USER_MODEL django.core.exceptions.ImproperlyConfigured：AUTH_USER_MODEL引用具有以下特征的模型'core.User' 尚未安装

要在settings.py中定义时-AUTH_USER_MODEL ='core.User'

是的，我有一个名为“ core”的应用程序，该应用程序已经在INSTALLED_APPS中

settings.py

import os
from decouple import config
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

SECRET_KEY = config('SECRET_KEY')

DEBUG = config('DEBUG', cast=bool)

ALLOWED_HOSTS = config('ALLOWED_HOSTS', cast=lambda v: [s.strip() for s in v.split(',')])

代码中的ident很好，但是这里不是哈哈

core / apps.py

from django.apps import AppConfig


class CoreConfig(AppConfig):
    name = 'core'

Answer 1

好吧，最后我得到了答案，在我的类User ....中，我们需要在元代码中删除 abstract = True ，然后一切正常！

class Meta:
verbose_name = _('user')
verbose_name_plural = _('users')
abstract = True

到

class Meta:
verbose_name = _('user')
verbose_name_plural = _('users')

AUTH_USER_MODEL指的是尚未安装的模型'core.User'
