我正在创建一个自定义
django用户,并在尝试使用它时收到以下错误.我得到的错误如下
AppRegistryNotReady: Models aren't loaded yet.
我的模特
class MyCustomUserManager(BaseUserManager):
def create_user(self, username, email, password=None, **kwargs):
if not username:
raise ValueError("Username must be defined for users")
if not kwargs.get('email'):
raise ValueError("Users must have a valid email")
user = self.model(username=username, email=self.normalize_email(email), **kwargs)
user.set_password(password)
user.save()
return user
def create_superuser(self, username, email, password, **kwargs):
user = self.create_user(username, email, password, **kwargs)
user.is_admin = True
user.save()
class MyCustomUser(AbstractBaseUser):
username = models.CharField(max_length=40, unique=True)
email = models.EmailField(max_length=255, unique=True, verbose_name=_('Email Address'))
date_of_birth = models.DateField(auto_now=False, blank=False, null=False, verbose_name=_("Ημ. Γεννήσεως"))
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
first_name = models.CharField(max_length=40, blank=False, null=False, verbose_name=_("Όνομα"))
last_name = models.CharField(max_length=40, blank=False, null=False, verbose_name=_("Επίθετο"))
friends = models.ManyToManyField('self', related_name="friends")
objects = MyCustomUserManager()
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email',]
def get_full_name(self):
return "%s %s" % (self.first_name, self.last_name)
def __unicode__(self):
return self.get_full_name()
class Meta:
verbose_name = _('Χρήστης')
verbose_name_plural = _('Χρήστες')
我还设置了设置文件以包含我的新自定义用户模型.
(在settings.py内)
AUTH_USER_MODEL = 'myapp.MyCustomUserModel'
登录shell时尝试使用我的新用户类型
from django.contrib.auth import get_user_model
user = get_user_model().objects.all()
我得到上面的错误. Django 1.7有什么问题吗?
P.S:我使用makemigrations并迁移来制作模型,我支持virtualenv.
最佳答案 从django 1.7开始,你不能在models.py文件中使用get_user_model,否则你会遇到这个问题.细节/原因可以在
referencing the user model中看到
要解决此问题,请在models.py文件中而不是使用get_user_model引用自定义用户模型,您需要从设置中导入名称.
from django.conf import settings
class MyModel(models.Model):
...
user = models.ForeignKey(settings.AUTH_USER_MODEL)
当您解决问题时,它将修复您的应用程序以及您的shell.
