I am surprised to see these solutions, for neither of them works. Sys.exit() just finishes off the current thread and raising a 'CommandError' only starts exception handling. Nor does raising a KeyboardInterrupt have any effect. Perhaps these solutions once worked with earlier versions, or with the server started in a different context.

The one solution I came across here is _thread.interrupt_main(). It stops the server after neatly finishing the current request.

from the docs:

from django.core.management.base import BaseCommand, CommandError
from polls.models import Poll

class Command(BaseCommand):
    help = 'Closes the specified poll for voting'

    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']:
            try:
                poll = Poll.objects.get(pk=poll_id)
            except Poll.DoesNotExist:
                raise CommandError('Poll "%s" does not exist' % poll_id)

            poll.opened = False
            poll.save()

            self.stdout.write(self.style.SUCCESS('Successfully closed poll "%s"' % poll_id))

i.e. you should raise a CommandError

though sys.exit generally ought to work fine too (I mean, you said it didn't for you - if it was me I'd be curious to work out why not anyway)
