データベースのinit（settings.py中）：DBオブジェクトの呼び出しが次のエラーで失敗し始める作成し、約20分後

class Command(BaseCommand): 
    def handle(self, *args, **kwargs): 
     os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings') 
     django.setup() 
    consumer = Consumer() 

    logging.info('Booting drive consumer') 

    while True:

     for message in messages: 
      ... 
      DriveEvent.objects.create(event_id=response['Id'], drive_id=drive_payload['drive_id']) 
      ... 

：労働者のコードは次のようになります。私の経験パー

DATABASES = { 
     'default': { 
      'ENGINE': 'sql_server.pyodbc', 
      'NAME': os.environ.get('DB_NAME'), 
      'HOST': os.environ.get('DB_HOST'),

       'extra_params': 'tds_version=7.2;' 
      } 
     } 
    } 

Answer 1

は、7.2バージョンはAzureのSQLデータベースをサポートしていませんtds_versionによって引き起こされているように見えます。他のSOスレッドpymssql: Connection to the database only works sometimesの私の答えは7.3に変更してください。

おそらく、GitHubのサードパーティープロジェクトmichiya/django-pyodbc-azureがあなたの詳細を知る手助けになるかもしれません。

希望します。
