adding clocking support to heroku with python django

This article teaches how to run background jobs in heroku.

I have my clock.py file, in the same directory where Procfile is.

Following is my clock.py file:

from apscheduler.scheduler import Scheduler
from subscription.views import send_subs_mail
sched = Scheduler()


@sched.cron_schedule(day_of_week='sat', hour=23)
def scheduled_job():
    print 'This job is run every saturday at 11pm.'
    send_subs_mail()

sched.start()

while True:
    pass

I have updated my Procfile, to look as follows:

web: newrelic-admin run-program gunicorn hellodjango.wsgi -b 0.0.0.0:$PORT -w 3 
clock: python clock.py

Earlier it used to look like:

web: newrelic-admin run-program gunicorn hellodjango.wsgi -b 0.0.0.0:$PORT -w 3

Having done all this, I do the following in my terminal: 

heroku ps:scale clock=1

And I get the following error:

Scaling clock processes... failed ! No such type as clock.

I have updated my requirements file, as mentioned in the article.

and here is the heroku logs

Each process type should be on it's own line, like so:

web: newrelic-admin run-program gunicorn hellodjango.wsgi -b 0.0.0.0:$PORT -w 3
clock: python clock.py

Hope that helps!
