# Overview

Django REST framework is a powerful and flexible toolkit that makes it easy to build Web APIs.

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 announcment][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

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

# Installation

Install using `pip`...

    pip install djangorestframework

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.

# Example

Let's take a look at a quick example of using REST framework to build a simple model-backed API.

We'll create a read-write API for accessing users and groups.

Here's our project's root `urls.py` module:

    from django.conf.urls.defaults import url, patterns, include
    from django.contrib.auth.models import User, Group
    from rest_framework import viewsets, routers

    # ViewSets define the view behavior.
    class UserViewSet(viewsets.ModelViewSet):
        model = User

    class GroupViewSet(viewsets.ModelViewSet):
        model = Group

    
    # Routers provide an easy way of automatically determining the URL conf
    router = routers.DefaultRouter()
    router.register(r'users', views.UserViewSet, name='user')
    router.register(r'groups', views.GroupViewSet, name='group')


    # Wire up our API using automatic URL routing.
    # Additionally, we include login URLs for the browseable API.
    urlpatterns = patterns('',
        url(r'^', include(router.urls)),
        url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
    )
