There are lots and lots of django applications do almost all kinds of works. So if you need a extra function which django framework do not provide, check those apps before write your own apps which may have bugs or not so robust. The articles introduce 10 top popular ones of them.

1. South

The "South" app comes first of course not by accident. It's the app that all django site should have. If you had enough of changing db schema everytime your change the models. Just forget the "syncdb" and use South, which handler schema migration automatically. A few key features of South:

  • Automatic migration creation
  • Database independence
  • App-savvy: Allow you to use migrations only for some of your apps
  • VCS-proof: Detect migrations conflict

2. django-debug-toolbar

3. haystack

Almost every sites need a search function, while almost no one knows how to write a search engine. Haystack is the one do such thing for you. It features a unified, familiar API that allows you to plug in different search backends (such as Solr, Whoosh, Xapian, etc.) without having to modify your code.

4. Celery

Celery is in fact not just a django app, is is an open source asynchronous task queue/job processing based on distributed message passing. With Celery you can make the long-time request execute asynchronous. It is focused on real-time operation, but supports scheduling as well. A simple example:

from celery.task import task

@task
def add(x, y):
    return x + y

You can execute the task in the background, or wait for it to finish:

>>> result = add.delay(4, 4)
>>> result.wait()

There is a tutorial about Integrating Celery with Django.

5. django-sentry

Django uses Python’s builtin logging module to perform system logging. However it's not very convenient for developer to check the log real time online. Sentry provides you with a generic interface to view and interact with your error logs. By default, it will catch any exception thrown by Django and store it in a database. With this it allows you to interact and view near real-time information to discover issues and more easily trace them in your application.
