Set up a scheduled job?

Question

I\'ve been working on a web app using Django, and I\'m curious if there is a way to schedule a job to run periodically.

Basically I just want to run through the dat

Answer 1

after the part of code,I can write anything just like my views.py :)

#######################################
import os,sys
sys.path.append('/home/administrator/development/store')
os.environ['DJANGO_SETTINGS_MODULE']='store.settings'
from django.core.management impor setup_environ
from store import settings
setup_environ(settings)

Interesting new pluggable Django app: django-chronograph

You only have to add one cron entry which acts as a timer, and you have a very nice Django admin interface into the scripts to run.

Answer 3

RabbitMQ and Celery have more features and task handling capabilities than Cron. If task failure isn't an issue, and you think you will handle broken tasks in the next call, then Cron is sufficient.

Celery & AMQP will let you handle the broken task, and it will get executed again by another worker (Celery workers listen for the next task to work on), until the task's max_retries attribute is reached. You can even invoke tasks on failure, like logging the failure, or sending an email to the admin once the max_retries has been reached.

And you can distribute Celery and AMQP servers when you need to scale your application.

We've open-sourced what I think is a structured app. that Brian's solution above alludes too. We would love any / all feedback!

https://github.com/tivix/django-cron

It comes with one management command:

./manage.py runcrons

That does the job. Each cron is modeled as a class (so its all OO) and each cron runs at a different frequency and we make sure the same cron type doesn't run in parallel (in case crons themselves take longer time to run than their frequency!)

Answer 5

I am not sure will this be useful for anyone, since I had to provide other users of the system to schedule the jobs, without giving them access to the actual server(windows) Task Scheduler, I created this reusable app.

Please note users have access to one shared folder on server where they can create required command/task/.bat file. This task then can be scheduled using this app.

App name is Django_Windows_Scheduler

If you want something more reliable than Celery, try TaskHawk which is built on top of AWS SQS/SNS.
