django.db.utils.OperationalError：（1054、 "フィールドリスト 'の" zoneclient_user.last_sync_time "が不明です）

Question

makemigrationsを実行すると問題ありません。しかし、私がbashで移行を実行することにした場合、私は以下のトレースバックを得ました。私はここで

django.db.utils.OperationalError: (1054, "Unknown column 'zoneclient_user.last_sync_time' in 'field list'") 

を関連するモデルの下を紹介します、私はその問題を解決する可能性がどのように

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 

私のモデルの一部ですか？私はこの問題がDateTimeFieldにあると思いますが、これまでのところ不明です。

P.S. Python 2.7.4でDjango 1.7.11を使用していることに注意してください。

Answer 1

django-guardianが匿名ユーザーを作成しようとすると、エラーが発生していることがトレースバックによって示されます。

User.objects.get(pk=guardian_settings.ANONYMOUS_USER_ID) 

それが動作するように取得するハック方法は、ユーザモデルが移行されるまで一時的にINSTALLED_APPSからDjangoの保護者を削除するかもしれません。
