A super simple but useful Django management command to print the active project settings

print_settings.py

from django.core.management.base import BaseCommand
from django.conf import settings


class Command(BaseCommand):
    help = "Print the active Django settings."

    def handle(self, *args, **options):
        for key in dir(settings):
            if key.startswith('__'):
                continue

            value = getattr(settings, key)
            print('%-40s : %s' % (key, value))

sample_output.sh

$ django print_settings | egrep 'DEBUG|INSTALLED_APPS' | egrep -v 'AUTH|LOGGING'
