django应用程序名称，但是安装了该应用程序

Question

我正在尝试通过添加自定义用户模型来修改Django的内置验证系统。自定义模型是在一个名为 Accord 的应用程序中定义的：

from django.db import models
from django.contrib.auth.models import AbstractUser
from django.conf import settings

# Create your models here.

COUNTRIES = settings.COUNTRY_CHOICES

class CustomUser(AbstractUser):
    zip_code = models.PositiveSmallIntegerField(blank=True, null=True)
    city = models.CharField(blank=True, null=True, max_length=64)
    address_street = models.CharField(blank=True, null=True, max_length=64)
    address_number = models.CharField(blank=True, null=True, max_length=32)
    country = models.CharField(blank=True, null=True, choices=COUNTRIES, max_length=8)

我以此方式更新了 settings.py 文件：

AUTH_USER_MODEL = accounts.CustomUser

我将 acception 作为已安装的应用程序：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'accounts',
    'store',
    'cart',
]

当我尝试运行 python manage.py makemigrations 命令以将更改应用于用户模型django丢弃此错误：

Traceback (most recent call last):
  File "C:\Users\uhlar\Dev\ecommerce\manage.py", line 22, in <module>

  File "C:\Users\uhlar\Dev\ecommerce\config\settings.py", line 149, in <module>
    AUTH_USER_MODEL = accounts.CustomUser
NameError: name 'accounts' is not defined

该错误不仅限于 eaccect 应用程序，无论我在哪个应用程序中尝试定义 customuser 模型，我仍在获取它。

如果有人知道是什么原因引起了问题，请帮助我解决问题。

Answer 1

/strong>设置＆nbsp; sup> [django-doc] 应该成为 string ，而不是（合格的）名称，因此：

# settings.py

# …
#  string literal 

Answer 2

如Willem提到的，您需要在 auth_user_model 内置 settings.py account> accounts.customeruser 模型中更新 auth_user_model 。此外，当您第一次运行迁移时，您将必须手动更新架构，Django将使用默认的 auth.user 进行多个外键等。请参阅docs 此处用于更改用户中间项目。
