Question

I want to check users’ subscribed dates for certain period. And send mail to users whose subscription is finishing (ex. reminds two days).
I think the best way is using thread and timer to check dates. But I have no idea how to call this function. I don’t want to make a separate program or shell. I want to combine this procedure to my django code. I tried to call this function in my settings.py file. But it seems it is not a good idea. It calls the function and creates thread every time I imported settings.

Answer 1

using Django-cron is much easier and simple

EDIT: Added a tip

from django_cron import cronScheduler, Job
class sendMail(Job):
       # period run every 300 seconds (5 minutes)
        run_every = 300

        def job(self):
                # This will be executed every 5 minutes
                datatuple = check_subscription_finishing()
                send_mass_mail(datatuple)
//and just register it             
cronScheduler.register(sendMail)
