Sqlite3 で Django Unittest を実行するとテーブルが見つからない

私はすでにこの投稿を見て、テスト用にプロジェクトをセットアップしようとしています。データベース コマンドを実行しようとすると、エラーが発生します。私が直面している問題は、manage.py syncdb を実行しようとすると、現在モデル ファイルと運用データベースにあるにもかかわらず、そのようなテーブルが存在しないというデータベース エラーが発生することです。

これがトレースバックです。

これは私のsettings.pyファイルにあります

if 'test' in sys.argv or 'jenkins' in sys.argv:
DATABASES = {
             'default': {
                         'ENGINE': 'django.db.backends.sqlite3',
                         'NAME': 'test_ndptc'
                         }
             }

上記の if ステートメントを true に設定して manage.py syncdb を実行しようとすると、同じエラーが発生します。

私もこの問題を抱えていました。テスト データベースを正しく識別するために、settings.py ファイルに TEST_NAME プロパティを追加する必要があることがわかりました。それは私のために問題を解決しました：

if 'test' in sys.argv:
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': os.path.join(os.path.dirname(__file__), 'test.db'),
            'TEST_NAME': os.path.join(os.path.dirname(__file__), 'test.db'),
        }
    }

単体テストでは、db NAME に常に ":memory:" を使用することをお勧めします。実際のデータベース パスを誤って指定したことがあり、単体テストの実行に 45 分かかりました。「:memory:」を指定すると、1分もかからずに実行されました。

if 'test' in sys.argv:
    DATABASES = {
        'default':{
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': ':memory:',
            'TEST_NAME': ':memory:',
        },
    }
