Feature to set the returncode of a django custom command

[stephanm]

In the docs:

​https://docs.djangoproject.com/en/2.1/howto/custom-management-commands/#django.core.management.BaseCommand.handle

I can see that the handle() function will return a string which goes to stdout.

But I would like to set (supplementary) an integer returncode like its done in sys.exit() see ​https://docs.python.org/3/library/sys.html#sys.exit

I didn't find any "official" way to do this, perhaps this is a new feature.

Thanks.

Thanks for the report, however answer for your question is already in the ticket description, i.e. you can use sys.exit(custom_number) in the handle().

Hi,

I stepped a little through the code after the handle() function returns.

Here I see in that I pass through the function
django.core.management.base.BaseCommand.run_from_argv()
which itself calls a connections.close_all() function at the end,
so using sys.exit() inside the handle() function will not give the exact same
behaviour as a "controlled" exit.

Or do I miss something?

See: ​run_from_argv(self, argv)

def run_from_argv(self, argv):
    try:
        self.execute(*args, **cmd_options)
    except Exception as e:
       #....
    finally:
        try:
            connections.close_all()
        except ImproperlyConfigured:
            # Ignore if connections aren't setup at this point (e.g. no
            # configured settings).
            pass

sys.exit() works fine, e.g.

class Command(BaseCommand):
    def handle(self, *args, **options):
        sys.exit(43)

> python manage.py test_command
> echo $?
43

All cleanup actions are honored (see ​sys.exit documentation). Please use one of support channels if you have more questions.
