Kronos makes it really easy to define and schedule tasks with cron

branch: master


Kronos makes it really easy to schedule tasks with cron.


$ pip install django-kronos

... and add kronos to INSTALLED_APPS.


Define tasks

Kronos collects tasks from cron modules in your project root and each of your applications:

# app/

import kronos
import random

@kronos.register('0 0 * * *')
def complain():
    complaints = [
        "I forgot to migrate our applications's cron jobs to our new server! Darn!",
        "I'm out of complaints! Damnit!"

    print random.choice(complaints)

Run tasks manually

$ python runtask complain
I forgot to migrate our applications's cron jobs to our new server! Darn!

Register tasks with cron

$ python installtasks
Installed 1 task.

You can review the crontab with a crontab -l command:

$ crontab -l
0 0 * * * /usr/bin/python /path/to/ runtask complain --settings=myprpoject.settings

Usually this line will work pretty well for you, but there can be some rare cases when it requires modification. You can achieve it with a number of settings variables used by kronos:

Python interpreter to build a crontab line (defaults to the interpreter you used to invoke the management command).
Management command to build a crontab line (defaults to in the current working directory).
Extra path which will be added as a --pythonpath option to the management command.
Extra string added at the end of the command. For dirty thinks like '> /dev/null 2>&1'

Define these variables in your file if you wish to alter crontab lines.

Johannes Gorset made this. You should tweet me if you can't get it to work. In fact, you should tweet me anyway.

Something went wrong with that request. Please try again.
