python - 查找错误 : No installed app with label 'user'

Question

我在运行以下代码时收到 LookupError: No installed app with label 'user':

from django.db import models

from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin

class UserManager(BaseUserManager):

    def _create_user(self, username, email, password, is_staff, is_superuser,
            **extra_fields):

        if not email:
            raise ValueError('El email debe de ser obligatorio')

        email = self.normalize_email(email)
        user = self.model(username=username, email=email, is_activate=True,
                is_staff=is_staff, is_superuser=is_superuser, **extra_fields)
        user.set_password(password)
        user.save(using = self.db)
        return user

    def create_user(self, username, email, password=None,
            **extra_fields):    
        return self._create_user(username, email, password, False, False, **extra_fields)

    def create_superuser(self, username, email, password,
            **extra_fields):
        return self._create_user(username, email, password, True, True, **extra_fields)

class User(AbstractBaseUser, PermissionsMixin):

    username = models.CharField(max_length=50, unique=True)
    email = models.EmailField(max_length=50, unique=True)
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    avatar = models.URLField()


    objects = UserManager()

    is_activate = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)

    USERNAME_FIELD = 'username'
    REQUIRE_FIELDS = ['email']

    def get_short_name(self):
        return self.username

错误的来源不是很明显，为什么会出现这个错误？

特别是哪一行正在寻找“用户”标签，为什么找不到它要找的东西？

你需要在settings.py中设置AUTH_USER_MODEL为自定义用户模型

并且还将具有自定义用户模型的应用包含到 settings.py 中的 INSTALLED_APPS
