在 Django rest framework 中，在使用自定义模型时，我需要给 AUTH_USER_MODEL 什么值？

Question

在 Django rest 框架中，我在模型文件夹中有不同的模型 -

settings.py

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'bootstrap3',
'rest_framework',
'myapp',
]


AUTH_USER_MODEL = 'myapp.models.UserModel.User'

• 我的应用程序
  • 设置
    • dev.py
  • 型号
    • UserModels.py
    • OrderModels.py
    • ReportingModels.py

UserModels.py

class User(AbstractBaseUser, GuardianUserMixin ,PermissionsMixin):

id = models.AutoField(_('id'),unique=True,primary_key=True)
email = models.EmailField(_('email address'),unique=True)
last_name = models.CharField(_('last name'), max_length=100, blank=True)
first_name = models.CharField(_('first name'), max_length=100, blank=True)
parent_id = models.IntegerField(_('parent id'), default=0)
organization_id = models.IntegerField(_('organization id'), default=0, null=True)
created_at = models.DateTimeField(_('date joined '), default=timezone.now())
updated_at = models.DateTimeField(_('date modified '), default=timezone.now())
incorrect_login = models.IntegerField(_('incorrect login frequency'), default=0)
soft_delete = models.BooleanField(_('soft delete'), default=False, )
group = models.ForeignKey('auth.Group', null=True)

USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['last_name, first_name, email,organization_id,group_id ']

class Meta:
    app_label = 'zeocuser'
    db_table = 'zeocuser_zeocuser'
    permissions = (
        (
            ('add_user_admin', 'add user admin'),
        )
    )


objects = UserManager()

现在，在 AUTH_USER_MODEL 的 settings.py 中，如果我给出如下值 - AUTH_USER_MODEL = 'myapp.models.UserModel.User' 它不接受它并给出以下错误 -

    app_label, model_name = model.split(".")
ValueError: too many values to unpack (expected 2)

但是，如果我将我的用户模型直接放在应用程序中的 models.py 文件中（而不将其放在模型文件夹中）并给出

AUTH_USER_MODEL = 'myapp.User'

它工作正常。但在那种情况下，我应该如何组织我的其他模型类。请建议。

Django 期望模型位于 .models 命名空间中。

正如https://docs.djangoproject.com/en/1.9/ref/applications/#how-applications-are-loaded 的第 2 点所述：

您必须在应用程序的 models.py 或 models/init.py 中定义或导入所有模型。否则，此时可能无法完全填充应用程序注册表，这可能会导致 ORM 出现故障。

在您的情况下，您需要在 myapp/models/__init__.py 文件中导入模型：

from .UserModels import User, <other models>
from .OrderModels import <other models>
from .ReportingModels import <other models>

等等
