How to make a Django custom management command argument not required?

Question

I am trying to write a custom management command in django like below-

class Command(BaseCommand):

    def add_arguments(self, parser):
        parser.add_argum         


        

Answer 1

You can use the dash syntax for optional keyword arguments:

class Command(BaseCommand):

    def add_arguments(self, parser):
        parser.add_argument("-d", "--delay", type=int)

    def handle(self, *args, **options):
        delay = options["delay"] if options["delay"] else 21
        print(delay)

Use:

$ python manage.py mycommand -d 4
4
$ python manage.py mycommand --delay 4
4
$ python manage.py mycommand
21
