optparse.make_option method is deprecated in Django 1.10 about django-cron HOT 7 CLOSED

@akhayyat - acknowledged and we'll work on a fix asap.

The fix is deployed https://pypi.python.org/pypi/django-cron/

Works perfectly! Thank you very much for the prompt resolution.

Doesn't it break backward-compatibility? Looks like it did. Because add_arguments was added in Django 1.8.

@bctiemann do you know recommended way to check Django version and depending on it define or not define attributes and functions?

from django-cron.

I'm not sure if there's a canonical way, but what if you check whether the add_arguments method is defined in the BaseCommand superclass?

@bctiemann thanks for your suggestion!

Django 1.10 has now been released, and this issue no longer is a deprecation warning; it breaks django-cron on Django 1.10. Upon running the manage.py runcrons, I get:

AttributeError: type object 'BaseCommand' has no attribute 'option_list'

Could a fixed release be made available? That would be greatly appreciated!

BTW, it seems to be common to check Django's version using django.get_version() (string) or django.VERSION (tuple) to support multiple versions and avoid breaking backward compatibility, e.g.:

if django.get_version().split('.') < ['1', '10']:
    # old version friendly code
else:
    # new version friendly code
