============================ 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``. .. _"batteries included" philosophy: http://docs.python.org/tut/node12.html#batteries-included admin ===== The automatic Django administrative interface. For more information, see `Tutorial 2`_. .. _Tutorial 2: ../tutorial02/ Requires the auth_ and contenttypes_ contrib packages to be installed. auth ==== Django's authentication framework. See the `authentication documentation`_. .. _authentication documentation: ../authentication/ comments ======== A simple yet flexible comments system. This is not yet documented. contenttypes ============ A light framework for hooking into "types" of content, where each installed Django model is a separate content type. This is not yet documented. csrf ==== A middleware for preventing Cross Site Request Forgeries See the `csrf documentation`_. .. _csrf documentation: ../csrf/ flatpages ========= A framework for managing simple "flat" HTML content in a database. See the `flatpages documentation`_. .. _flatpages documentation: ../flatpages/ Requires the sites_ contrib package to be installed as well. formtools ========= A set of high-level abstractions for Django forms (django.newforms). django.contrib.formtools.preview -------------------------------- An abstraction of the following workflow: "Display an HTML form, force a preview, then do something with the submission." See the `form preview documentation`_. .. _form preview documentation: ../form_preview/ humanize ======== A set of Django template filters useful for adding a "human touch" to data. To activate these filters, add ``'django.contrib.humanize'`` to your ``INSTALLED_APPS`` setting. Once you've done that, use ``{% load humanize %}`` in a template, and you'll have access to these filters: apnumber -------- For numbers 1-9, returns the number spelled out. Otherwise, returns the number. This follows Associated Press style. Examples: * ``1`` becomes ``'one'``. * ``2`` becomes ``'two'``. * ``10`` becomes ``10``. You can pass in either an integer or a string representation of an integer. intcomma -------- Converts an integer to a string containing commas every three digits. Examples: * ``4500`` becomes ``'4,500'``. * ``45000`` becomes ``'45,000'``. * ``450000`` becomes ``'450,000'``. * ``4500000`` becomes ``'4,500,000'``. You can pass in either an integer or a string representation of an integer. intword ------- Converts a large integer to a friendly text representation. Works best for numbers over 1 million. Examples: * ``1000000`` becomes ``'1.0 million'``. * ``1200000`` becomes ``'1.2 million'``. * ``1200000000`` becomes ``'1.2 billion'``. Values up to 1000000000000000 (one quadrillion) are supported. You can pass in either an integer or a string representation of an integer. ordinal ------- Converts an integer to its ordinal as a string. Examples: * ``1`` becomes ``'1st'``. * ``2`` becomes ``'2nd'``. * ``3`` becomes ``'3rd'``. You can pass in either an integer or a string representation of an integer. naturalday ---------- **New in Django development version** For dates that are the current day or within one day, return "today", "tomorrow" or "yesterday", as appropriate. Otherwise, format the date using the passed in format string. **Argument:** Date formatting string as described in default tag now_. .. _now: ../templates/#now Examples (when 'today' is 17 Feb 2007): * ``16 Feb 2007`` becomes ``yesterday``. * ``17 Feb 2007`` becomes ``today``. * ``18 Feb 2007`` becomes ``tomorrow``. * Any other day is formatted according to given argument or the `DATE_FORMAT`_ setting if no argument is given. .. _DATE_FORMAT: ../settings/#date_format localflavor =========== A collection of various Django snippets that are useful only for a particular country or culture. For example, ``django.contrib.localflavor.usa.forms`` contains a ``USZipCodeField`` that you can use to validate U.S. zip codes. markup ====== A collection of template filters that implement common markup languages: * ``textile`` -- implements `Textile`_ * ``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 ``INSTALLED_APPS`` setting. Once you've done that, use ``{% load markup %}`` in a template, and you'll have access to these filters. For more documentation, read the source code in django/contrib/markup/templatetags/markup.py. .. _Textile: http://en.wikipedia.org/wiki/Textile_%28markup_language%29 .. _Markdown: http://en.wikipedia.org/wiki/Markdown .. _ReST (ReStructured Text): http://en.wikipedia.org/wiki/ReStructuredText redirects ========= A framework for managing redirects. See the `redirects documentation`_. .. _redirects documentation: ../redirects/ sessions ======== A framework for storing data in anonymous sessions. See the `sessions documentation`_. .. _sessions documentation: ../sessions/ sites ===== A light framework that lets you operate multiple Web sites off of the same database and Django installation. It gives you hooks for associating objects to one or more sites. See the `sites documentation`_. .. _sites documentation: ../sites/ sitemaps ======== A framework for generating Google sitemap XML files. See the `sitemaps documentation`_. .. _sitemaps documentation: ../sitemaps/ syndication =========== A framework for generating syndication feeds, in RSS and Atom, quite easily. See the `syndication documentation`_. .. _syndication documentation: ../syndication_feeds/ webdesign ========= Helpers and utilties targeted primarily at web designers rather than web developers. See the `web design helpers documentation`_. .. _web design helpers documentaion`: ../webdesign/ Other add-ons ============= If you have an idea for functionality to include in ``contrib``, let us know! Code it up, and post it to the `django-users mailing list`_. .. _django-users mailing list: http://groups.google.com/group/django-users
