django-cron only working with --force

[zoo198]

Hi, its working in local no problem but its not working in production environment. No errors nothing at all. I can see that it works with --force but we need to schedule this. Any help appreciated.

python manage.py runcrons "calculator.ptrn_update_cron.RunCronJob"

This command working in local but production its not entering into "do" method.
