[Django]-Examples of Django and Celery: Periodic Tasks

What’s wrong with the example from the docs?

from celery.task import PeriodicTask
from clickmuncher.messaging import process_clicks
from datetime import timedelta


class ProcessClicksTask(PeriodicTask):
    run_every = timedelta(minutes=30)

    def run(self, **kwargs):
        process_clicks()

You could write the same task using a decorator:

from celery.task.schedules import crontab
from celery.task import periodic_task

@periodic_task(run_every=crontab(minute="*/30"))
def process_clicks():
    ....

The decorator syntax simply allows you to turn an existing function/task into a periodic task without modifying them directly.

For the tasks to be executed celerybeat must be running.
