New description:
Are there any plans to add support for the following?
{{{
from django.core.management import BaseCommand
class Command(BaseCommand):
def add_arguments(self, parser):
group = parser.add_mutually_exclusive_group(required=True)
group.add_argument('--foo', nargs='+', type=int)
def handle(self, *args, **options):
pass
}}}
When calling the above using `call_command`:
{{{
call_command('call_command_test', foo=[1, 2, 3])
# Raises: django.core.management.base.CommandError: Error: argument --foo:
invalid int value: '[1, 2, 3]'
call_command('call_command_test', '--foo=1', '--foo=2', '--foo=3')
# Option 'foo' will be of value [3]
}}}
I can't think of any workarounds other than setting `type=str` (somehow,
that works fine) and coercing manually. Thank you!
