python - Running Django management command from tests? -

i have django management command create materialized views on database, runs follows (i store database login details in environment variables):

python manage.py create_db_matviews $db_name $db_user $db_pass 

the management command code looks this:

 class command(basecommand):    def handle(self, *args, **options):     db_name = args[0]     db_user = args[1]     db_pass = args[2]     self.conn = psycopg2.connect(database=db_name, user=db_user,                                  password=db_pass) 

now want run management command inside tests, materialized views created on test data. not work:

def setupmodule():     # load fixtures, then...      management.call_command('create_db_matviews',                         ['test', 'test', 'test'], verbosity=0) 

it fails follows:

....  db_user = args[1] indexerror: tuple index out of range 

how can supply arguments management script in way wants?

also, credentials should use access test database?

it fails because in tuple of args set 1 argument, list of 3 values. should use:

management.call_command('create_db_matviews', 'test', 'test', 'test', verbosity=0) 

*agrs pythons way send multiple parameters , of them send tuple. send (['test', 'test', 'test', ],) args[0] ['test', 'test', 'test', ], not 'test'
