初めてDjango 1.9を移行するとテーブルが作成されない

Question

これまでにこの問題は発生していません。私は数え切れないほどのプロジェクトを開始し、私が初めて「makemigrations」を実行するために行ってきました何の問題もなかったこのプロジェクトでは、私はエラーになっておくました：。

django.db.utils.OperationalError: no such table: accounts_customuser

ポイントですが、表にはありません。 。..itは、ものを作ることになって

私は空想のデータベースを実行していない、それだけでsqlite3のだだ

INSTALLED_APPS = [ 
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 
    'django.contrib.sites', 
    'django_extensions', 
    'rest_framework', 
    'rest_framework.authtoken', 
    # 'djoser', 
    # 'django_comments', 
    # 'django_comments_xtd', 
    'accounts', 
    'blog', 
] 

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.sqlite3', 
     'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), 
    } 
}

私のPostViewSetに問題がありますか？以前は複雑なクエリを実行したことがないので、正しい構文かどうかはわかりません。私はこの問題は、URLの設定がロードされ、テーブルも作成されている前に、ビューをインポートしたとき、あなたのCustomUser.objects.get(pk=1)クエリが実行されていることであるhere

class PostViewSet(ModelViewSet): 
    some_user = CustomUser.objects.get(pk=1) 
    queryset = Post.objects.filter(
    Q(poster=some_user) | 
    Q(poster__friends__creator=some_user) | 
    Q(poster__friendship_creator__friend=some_user)).distinct() 
    serializer_class = PostSerializer

からこれを得ました。これを解決するには、コードをget_querysetメソッドに移動します。

class PostViewSet(ModelViewSet): 
    def get_queryset(self): 
     some_user = CustomUser.objects.get(pk=1) 
     return Post.objects.filter(
      Q(poster=some_user) | 
      Q(poster__friends__creator=some_user) | 
      Q(poster__friendship_creator__friend=some_user)).distinct() 
    serializer_class = PostSerializer
