Google, Github and Stackoverflow bring up django-schedule and django-mailer, but these are both old projects with not much development, if at all in the last ~ 2years.
My use case:
User sets him/herself reminders to be send by email. A reminder is simply a chunk of text, some fields to determine when to send the reminder.
Reminders can be repeating daily or weekly. Reminders can also be one-off reminders.
Is there a good, current app for this with Django 1.3/1.4? Perhaps the solution is to write the reminder models myself, and then send with some scheduler – django-celery or django-cronograph?
If you going to do it by yourself, try the Advanced Python Scheduler:
http://packages.python.org/APScheduler/
It’s useful especially when you can not or will not use the cron.
