2 The "django.contrib" add-ons
3 ============================
5 Django aims to follow Python's `"batteries included" philosophy`_. It ships
6 with a variety of extra, optional tools that solve common Web-development
9 This code lives in ``django/contrib`` in the Django distribution. This document
10 gives a rundown of the packages in ``contrib``, along with any dependencies
15 For most of these add-ons -- specifically, the add-ons that include either
16 models or template tags -- you'll need to add the package name (e.g.,
17 ``'django.contrib.admin'``) to your ``INSTALLED_APPS`` setting and re-run

25 The automatic Django administrative interface. For more information, see
26 `Tutorial 2`_ and the `admin documentation`_.
28 .. _Tutorial 2: ../tutorial02/
29 .. _admin documentation: ../admin/
31 Requires the auth_ and contenttypes_ contrib packages to be installed.
36 Django's authentication framework.
38 See the `authentication documentation`_.
40 .. _authentication documentation: ../authentication/
45 A simple yet flexible comments system. This is not yet documented.
50 A light framework for hooking into "types" of content, where each installed
51 Django model is a separate content type.
53 See the `contenttypes documentation`_.
55 .. _contenttypes documentation: ../contenttypes/
60 A middleware for preventing Cross Site Request Forgeries
62 See the `csrf documentation`_.
64 .. _csrf documentation: ../csrf/
69 A framework for managing simple "flat" HTML content in a database.
71 See the `flatpages documentation`_.
73 .. _flatpages documentation: ../flatpages/
75 Requires the sites_ contrib package to be installed as well.
80 A set of high-level abstractions for Django forms (django.forms).
82 django.contrib.formtools.preview
83 --------------------------------
85 An abstraction of the following workflow:
87 "Display an HTML form, force a preview, then do something with the submission."
89 See the `form preview documentation`_.
91 .. _form preview documentation: ../form_preview/
96 A set of Django template filters useful for adding a "human touch" to data.
97 To activate these filters, add ``'django.contrib.humanize'`` to your
98 ``INSTALLED_APPS`` setting. Once you've done that, use ``{% load humanize %}``
99 in a template, and you'll have access to these filters:
104 For numbers 1-9, returns the number spelled out. Otherwise, returns the
105 number. This follows Associated Press style.
109 * ``1`` becomes ``'one'``.
110 * ``2`` becomes ``'two'``.
111 * ``10`` becomes ``10``.
113 You can pass in either an integer or a string representation of an integer.
118 Converts an integer to a string containing commas every three digits.
122 * ``4500`` becomes ``'4,500'``.
123 * ``45000`` becomes ``'45,000'``.
124 * ``450000`` becomes ``'450,000'``.
125 * ``4500000`` becomes ``'4,500,000'``.
127 You can pass in either an integer or a string representation of an integer.
132 Converts a large integer to a friendly text representation. Works best for
133 numbers over 1 million.
137 * ``1000000`` becomes ``'1.0 million'``.
138 * ``1200000`` becomes ``'1.2 million'``.
139 * ``1200000000`` becomes ``'1.2 billion'``.
141 Values up to 1000000000000000 (one quadrillion) are supported.
143 You can pass in either an integer or a string representation of an integer.
148 Converts an integer to its ordinal as a string.
152 * ``1`` becomes ``'1st'``.
153 * ``2`` becomes ``'2nd'``.
154 * ``3`` becomes ``'3rd'``.
156 You can pass in either an integer or a string representation of an integer.
161 **New in Django development version**
163 For dates that are the current day or within one day, return "today",
164 "tomorrow" or "yesterday", as appropriate. Otherwise, format the date using
165 the passed in format string.
167 **Argument:** Date formatting string as described in default tag now_.
169 .. _now: ../templates/#now
171 Examples (when 'today' is 17 Feb 2007):
173 * ``16 Feb 2007`` becomes ``yesterday``.
174 * ``17 Feb 2007`` becomes ``today``.
175 * ``18 Feb 2007`` becomes ``tomorrow``.
176 * Any other day is formatted according to given argument or the
177 `DATE_FORMAT`_ setting if no argument is given.
179 .. _DATE_FORMAT: ../settings/#date_format
184 A collection of various Django snippets that are useful only for a particular
185 country or culture. For example, ``django.contrib.localflavor.us.forms``
186 contains a ``USZipCodeField`` that you can use to validate U.S. zip codes.
188 See the `localflavor documentation`_.
190 .. _localflavor documentation: ../localflavor/
195 A collection of template filters that implement common markup languages:
197 * ``textile`` -- implements `Textile`_
198 * ``markdown`` -- implements `Markdown`_
199 * ``restructuredtext`` -- implements `ReST (ReStructured Text)`_
201 In each case, the filter expects formatted markup as a string and returns a
202 string representing the marked-up text. For example, the ``textile`` filter
203 converts text that is marked-up in Textile format to HTML.
205 To activate these filters, add ``'django.contrib.markup'`` to your
206 ``INSTALLED_APPS`` setting. Once you've done that, use ``{% load markup %}`` in
207 a template, and you'll have access to these filters. For more documentation,
208 read the source code in django/contrib/markup/templatetags/markup.py.

226 A framework for storing data in anonymous sessions.

235 A light framework that lets you operate multiple Web sites off of the same
236 database and Django installation. It gives you hooks for associating objects to

246 A framework for generating Google sitemap XML files.
