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!
