Django：模型类 user.models.Users 未声明显式 app_label 并且不在 INSTALLED_APPS 中的应用程序中

姜戈版本：2.0

错误：模型类 user.models.Users 未声明显式 app_label 并且不在 INSTALLED_APPS 中的应用程序中。
我刚刚将模型用户添加到我的视图中。

base.py:

DJANGO_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites'
]

THIRD_PARTY_APPS = [
    'allauth',
    'allauth.account',
    'allauth.socialaccount',
]

LOCAL_APPS = [
    'clockingIn.users.apps.UserConfig',
]

INSTALLED_APPS = DJANGO_APPS + THIRD_PARTY_APPS + LOCAL_APPS

视图.py：

from django.http import HttpResponse
from django.contrib.auth.mixins import LoginRequiredMixin
from django.views import generic

from .models import Users


class UsersList(LoginRequiredMixin, generic.ListView):
    raise_exception = True
    model = Users

    def get_queryset(self):
        return ""


class UsersDetail(LoginRequiredMixin, generic.DetailView):
    raise_exception = True
    model = Users

    def get_queryset(self):
        return ""

模型.py:

class Users(AbstractUser):

    uuid = models.UUIDField(_('uuid'), primary_key=True, default=uuid.uuid4)
    first_name = models.CharField(_('first name'), max_length=127, blank=True)
    last_name = models.CharField(_('first name'), max_length=127, blank=True)
    email = models.EmailField(_('email'), max_length=127, unique=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    objects = CustomUserManager()

事实上，问题是我忘记了 config/urls.py 中用户之前的“clockingIn”：url(r'^users/', include('clockingIn.users.urls'))
