## Installation ##

Recommended installation:

    pip install django-cassandra-engine

## Basic Usage ##

1. Add `django_cassandra_engine` to `INSTALLED_APPS` in your `settings.py` file:

        INSTALLED_APPS = ('django_cassandra_engine',) + INSTALLED_APPS

2. 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

                    }

                }

            }

        }

3. Define some model:

        # 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)

4. Run `./manage.py sync_cassandra`

5. Done!

## Connect to Cassandra with a Cloud Config bundle ##

To connect to a hosted Cassandra cluster that provides a secure connection bundle (ex. DataStax Astra) change the `DATABASES` setting of your settings.py:

        DATABASES = {

            'default': {

                'ENGINE': 'django_cassandra_engine',

                'NAME': 'keyspace_name',

                'TEST_NAME': 'table_name',

                'USER': 'token',

                'PASSWORD': token_value,

                'OPTIONS': {

                    'connection': {

                        'cloud': {

                            'secure_connect_bundle': '/path/to/secure/bundle.zip'

                        },

                    }

                }

            }

        }
