Django Cassandra Engine - Getting Started

• Add django-cassandra-engine to INSTALLED_APPS in your settings.py file:

    INSTALLED_APPS = ['django_cassandra_engine'] + INSTALLED_APPS

Important note

This app should be the first app on INSTALLED_APPS list. This rule applies only to Django >= 1.7.

• Change DATABASES setting:

    DATABASES = {
        'default': {
            'ENGINE': 'django_cassandra_engine',
            'NAME': 'db',
            'TEST_NAME': 'test_db',
            'HOST': 'db1.example.com,db2.example.com',
            'OPTIONS': {
                'replication': {
                    'strategy_class': 'SimpleStrategy',
                    'replication_factor': 1
                }
            }
        }
    }

• Define some model(s) in your Django app:

    #  myapp/models.py
    import uuid
    from cassandra.cqlengine import columns
    from django_cassandra_engine.models import DjangoCassandraModel

    class ExampleModel(DjangoCassandraModel):
        example_id   = columns.UUID(primary_key=True, default=uuid.uuid4)
        example_type = columns.Integer(index=True)
        created_at   = columns.DateTime()
        description  = columns.Text(required=False)

• Run ./manage.py sync_cassandra in order to sync your models with Cassandra.

• Done!
