# Django REST framework

**Web APIs for Django, made easy.**

Django REST framework is a flexible, powerful library that makes it incredibly easy to build Web APIs.  It is designed as a modular and easy to customize architecture, based on Django's class based views.

Web APIs built using REST framework are fully self-describing and web browseable - a huge useability win for your developers.  It also supports a wide range of media types, authentication and permission policies out of the box.

If you are considering using REST framework for your API, we recommend reading the [REST framework 2 announcement][rest-framework-2-announcement] which gives a good overview of the framework and it's capabilities.

There is also a sandbox API you can use for testing purposes, [available here][sandbox].

**Below**: *Screenshot from the browseable API*

## Requirements

REST framework requires the following:

* Python (2.6.5+, 2.7, 3.2, 3.3)
* Django (1.3, 1.4, 1.5)

The following packages are optional:

* [Markdown][markdown] (2.1.0+) - Markdown support for the browseable API.
* [PyYAML][yaml] (3.10+) - YAML content-type support.
* [defusedxml][defusedxml] (0.3+) - XML content-type support.
* [django-filter][django-filter] (0.5.4+) - Filtering support.
* [django-oauth-plus][django-oauth-plus] (2.0+) and [oauth2][oauth2] (1.5.211+) - OAuth 1.0a support.
* [django-oauth2-provider][django-oauth2-provider] (0.2.3+) - OAuth 2.0 support.

**Note**: The `oauth2` python package is badly misnamed, and actually provides OAuth 1.0a support.  Also note that packages required for both OAuth 1.0a, and OAuth 2.0 are not yet Python 3 compatible.

## Installation

Install using `pip`, including any optional packages you want...

    pip install djangorestframework
    pip install markdown  # Markdown support for the browseable API.
    pip install pyyaml    # YAML content-type support.
    pip install django-filter  # Filtering support

...or clone the project from github.

    git clone git@github.com:tomchristie/django-rest-framework.git
    cd django-rest-framework
    pip install -r requirements.txt
    pip install -r optionals.txt

Add `'rest_framework'` to your `INSTALLED_APPS` setting.

    INSTALLED_APPS = (
        ...
        'rest_framework',        
    )

If you're intending to use the browseable API you'll probably also want to add REST framework's login and logout views.  Add the following to your root `urls.py` file.

    urlpatterns = patterns('',
        ...
        url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
    )

Note that the URL path can be whatever you want, but you must include `'rest_framework.urls'` with the `'rest_framework'` namespace.

## Quickstart

Can't wait to get started?  The [quickstart guide][quickstart] is the fastest way to get up and running, and building APIs with REST framework.

## Tutorial

The tutorial will walk you through the building blocks that make up REST framework.   It'll take a little while to get through, but it'll give you a comprehensive understanding of how everything fits together, and is highly recommended reading.

* [1 - Serialization][tut-1]
* [2 - Requests & Responses][tut-2]
* [3 - Class based views][tut-3]
* [4 - Authentication & permissions][tut-4]
* [5 - Relationships & hyperlinked APIs][tut-5]

## API Guide

The API guide is your complete reference manual to all the functionality provided by REST framework.

* [Requests][request]
* [Responses][response]
* [Views][views]
* [Generic views][generic-views]
* [Parsers][parsers]
* [Renderers][renderers]
* [Serializers][serializers]
* [Serializer fields][fields]
* [Serializer relations][relations]
* [Authentication][authentication]
* [Permissions][permissions]
* [Throttling][throttling]
* [Filtering][filtering]
* [Pagination][pagination]
* [Content negotiation][contentnegotiation]
* [Format suffixes][formatsuffixes]
* [Returning URLs][reverse]
* [Exceptions][exceptions]
* [Status codes][status]
* [Settings][settings]

## Topics

General guides to using REST framework.

* [AJAX, CSRF & CORS][ajax-csrf-cors]
* [Browser enhancements][browser-enhancements]
* [The Browsable API][browsableapi]
* [REST, Hypermedia & HATEOAS][rest-hypermedia-hateoas]
* [2.0 Announcement][rest-framework-2-announcement]
* [2.2 Announcement][2.2-announcement]
* [Release Notes][release-notes]
* [Credits][credits]

## Development

If you want to work on REST framework itself, clone the repository, then...

Build the docs:

    ./mkdocs.py

Run the tests:

    ./rest_framework/runtests/runtests.py

To run the tests against all supported configurations, first install [the tox testing tool][tox] globally, using `pip install tox`, then simply run `tox`: 

    tox

## Support

For support please see the [REST framework discussion group][group], try the  `#restframework` channel on `irc.freenode.net`, or raise a  question on [Stack Overflow][stack-overflow], making sure to include the ['django-rest-framework'][django-rest-framework-tag] tag.

[Paid support is available][paid-support] from [DabApps][dabapps], and can include work on REST framework core, or support with building your REST framework API.  Please [contact DabApps][contact-dabapps] if you'd like to discuss commercial support options.

For updates on REST framework development, you may also want to follow [the author][twitter] on Twitter.
