Since argparse is adopted, int() argument should be passed as str() and
let argparse to handle it. This is better mentioned in the doc.
See below example:
{{{
# management/commands/callme.py
from django.core.management.base import BaseCommand, CommandError
class Command(BaseCommand):
def add_arguments(self, parser):
parser.add_argument('poll_id', nargs='+', type=int)
def handle(self, *args, **options):
for poll_id in options['poll_id']:
self.stdout.write('%d' % poll_id)
# python manage.py shell
>>> from django.core.management import call_command
>>> call_command('callme', 1, 2, 3)
Traceback (most recent call last):
