Django argparse: Unrecognized Arguments –settings?

February 4, 2022

I’ve looked at the other SO threads about unrecognized argparse arguments, but none of them seem to match up with my situation.

Here’s my argparse code, located at apps/create_pdf/management/commands/create_pdf.py:


from django.core.management.base import BaseCommand, CommandError

class Command(BaseCommand):
    help = 'html to pdf for specified website.'

    def add_arguments(self, parser):
        print('cp#1')

        parser = argparse.ArgumentParser(description='html to pdf for specified website')
        parser.add_argument('-w', '--website', nargs =1, action = 'store', choices = ['SITE_1', 'SITE_2'], default='', help='site to be scraped.')
        args = parser.parse_args()

        print(args)
        breakpoint()

    def handle(self, *args, **options):
        print('cp#2')

        # create_pdf_from_html()

I run this from the terminal like so:

python3 manage.py create_pdf --website=SITE_1 --settings=server_config.settings

…and I’m getting this error:

manage.py: error: unrecognized arguments: create_pdf –settings=server_config.settings

The settings path is correct and if I’m not using argparse, everything runs fine.

What am I missing?

>Solution :

The correct way to add arguments to your command:

from django.core.management.base import BaseCommand, CommandError

class Command(BaseCommand):
    help = 'html to pdf for specified website.'

    def add_arguments(self, parser):
        parser.add_argument('-w', '--website', nargs =1, action = 'store', choices = ['SITE_1', 'SITE_2'], default='', help='site to be scraped.')


    def handle(self, *args, **options):
        print(options['website'])

        # create_pdf_from_html()
