如果我运行makemigrations，那很好。但是，如果我决定在bash中运行迁移，那么我得到了以下回溯。我将在相关模型下面显示

django.db.utils.OperationalError: (1054, "Unknown column 'zoneclient_user.last_sync_time' in 'field list'")
这是我模特的一部分
class User(AbstractUser):
...
last_sync_time = models.DateTimeField(
_('Last sync time'), blank=True, null=True)
@property
def is_synch(self):
now = datetime.datetime.now()
if not self.last_sync_time:
return False
elif self.last_sync_time < (now + datetime.timedelta(minutes=5)):
return False
else:
return True
我该如何解决这个问题？我认为问题出在DateTimeField上，但到目前为止还不清楚。
P.S。请注意，我正在使用Django 1.7.11和python 2.7.4。

回溯显示当django-guardian尝试创建匿名用户时发生错误。
User.objects.get(pk=guardian_settings.ANONYMOUS_USER_ID)
让它发挥作用的黑客方法可能是暂时从您的INSTALLED_APPS删除django监护人，直到迁移用户模型为止。
