The "django.contrib" add-ons
|
|
============================
|
|
|
|
Django aims to follow Python's `"batteries included" philosophy`_. It ships
|
|
with a variety of extra, optional tools that solve common Web-development
|
|
problems.
|
|
|
|
This code lives in ``django/contrib`` in the Django distribution. This document
|
|
gives a rundown of the packages in ``contrib``, along with any dependencies
|
|
those packages have.
|
|
|
|
.. admonition:: Note
|
|
|
|
For most of these add-ons -- specifically, the add-ons that include either
|
|
models or template tags -- you'll need to add the package name (e.g.,
|
|
``'django.contrib.admin'``) to your ``INSTALLED_APPS`` setting and re-run
|
|
``manage.py syncdb``.
|

localflavor
|

|
|
* ``markdown`` -- implements `Markdown`_
|
|
* ``restructuredtext`` -- implements `ReST (ReStructured Text)`_
|
|
|
|
In each case, the filter expects formatted markup as a string and returns a
|
|
string representing the marked-up text. For example, the ``textile`` filter
|
|
converts text that is marked-up in Textile format to HTML.
|
|
|
|
To activate these filters, add ``'django.contrib.markup'`` to your

|
a template, and you'll have access to these filters. For more documentation,
|
|
