A simple scheduling system that lets you define jobs that get performed at various intervals

Bambu Cron makes it easy to define scheduled tasks that can run as rarely as once a year os often as once a minute. The syadmin only needs to add an extra line to the crontab file belonging to the user with permission to perform actions on the site, and and Bambu Cron will do the rest.

Jobs are defined very simply, and a flag is set to alert the system that a job is running, so that frequent jobs that take longer than a minute to run, don't run in parallel.

This is part of a toolset called Bambu Tools. It's being moved from a namespace of bambu to its own 'root-level' package, along with all the other tools in the set. If you're upgrading from a version prior to 2.0, please make sure to update your code to use bambu_cron rather than bambu_cron.

Install the package via Pip:

pip install bambu-cron

Add it to your INSTALLED_APPS list:

INSTALLED_APPS = (
    ...
    'bambu_cron'
)

Run manage.py syncdb or manage.py migrate to setup the database tables.

You define cron jobs and register them in a file called cron.py, which you add to your Django app. Only cron.py files found within an app referenced in the INSTALLED_APPS setting will be discovered.

import bambu_cron

class EmailDigestJob(bambu_cron.CronJob):
    frequency = bambu_cron.frequency.DAY
    
    def run(self, logger):
        # Send a digest email on a daily basis
        ...

bambu_cron.site.register(EmailDigestJob)

This registers the EmailDigestJob job. Once registered, you'll need to call python manage.py cron --setup to allow Bambu Cron to store details of the job in the database.
