Add this method to your Command class:
def add_arguments(self, parser):
parser.add_argument('my_int_argument', type=int)
You can then use your option in the code, like this:
def handle(self, *args, **options):
my_int_argument = options['my_int_argument']
The benefit of doing it this way is that the help
output is automatically generated for manage.py my_command --help
