django cassnadra migration

[antonzhelyazkov]

Hi I am new in django

I tried to connect django to cassandra. here are my modules:

cassandra-driver (3.25.0)
cassandra-pylib (0.0.0)
click (8.0.1)
Django (3.2.7)
django-cassandra-engine (1.6.3)

here are my settings.py

INSTALLED_APPS = ['django_cassandra_engine'] + INSTALLED_APPS

DATABASES = {
    # 'default': {
    #     'ENGINE': 'django.db.backends.sqlite3',
    #     'NAME': BASE_DIR / 'db.sqlite3',
    # }
    'default': {
        'ENGINE': 'django_cassandra_engine',
        'NAME': 'dvr',
        'HOST': '127.0.0.1',
        'USER': 'user',
        'PASSWORD': 'pass',
        'OPTIONS': {
            'replication': {
                'strategy_class': 'NetworkTopologyStrategy',
                'dc1': 1
            },
            'connection': {
                    'consistency': ConsistencyLevel.LOCAL_ONE,
                    'retry_connect': True,
                    'protocol_version': 4
                    # + All connection options for cassandra.cluster.Cluster()
            }
        }
    }
}

when I try to run migrations I have an error:

/root/python38/bin/python3 /root/cutter2/cutter/manage.py sync_cassandra

Could you help me to run migrations

Hello! You don't need to run migrations. python manage.py sync_cassandra does the trick for you, so every time you add a column to your model you have to call sync_cassandra and that's it.
