Hello everyone, I'm struggling with something, how should I call a command with no-value arguments? I'm using dbbackup and I need to pass the -c value for cleaning ./manage.py dbbackup -c, which one of the following options is the right one?

 ('0 0 * * *', 'django.core.management.call_command', ['dbbackup -c'])
 ('0 0 * * *', 'django.core.management.call_command', ['dbbackup', '-c'])
 ('0 0 * * *', 'django.core.management.call_command', ['dbbackup'], {'c': None})

Thanks in advance!
