I trying to use Cassandra database for my Django rest application. When I am using SQLite database the migration working fine. However, when I am changing the database to use cassandra I am getting the following error.
TypeError: Unknown option(s) for sync_cassandra command:
app_label, fake, fake_initial, interactive, migration_name, run_syncdb.
Valid options are database, help, no_color, pythonpath, settings, skip_checks, stderr, stdout, traceback, verbosity, version.
I am running cassandra service in another shell. Also I have created a Keyspace named project_db using cqlsh.
The setting.py file is given below. I am getting the same error even I am changing my database to cassandra only i.e. removing the SQLite database.
