Django REST framework

Awesome web-browseable Web APIs.

Note: Full documentation for the project is available at http://www.django-rest-framework.org.

Overview

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

Some reasons you might want to use REST framework:

The Web browseable API is a huge useability win for your developers.
Authentication policies including OAuth1a and OAuth2 out of the box.
Serialization that supports both ORM and non-ORM data sources.
Customizable all the way down - just use regular function-based views if you don't need the more powerful features.
Extensive documentation, and great community support.

There is a live example API for testing purposes, available here.

Requirements

Python (2.6.5+, 2.7, 3.2, 3.3)
Django (1.3, 1.4, 1.5, 1.6)

Installation

Install using pip...

pip install djangorestframework

Add 'rest_framework' to your INSTALLED_APPS setting.

INSTALLED_APPS = (
    ...
    'rest_framework',        
)

Example

Let's take a look at a quick example of using REST framework to build a simple model-backed 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', UserViewSet)
router.register(r'groups', GroupViewSet)


# 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'))
)

We'd also like to configure a couple of settings for our API.

Add the following to your settings.py module:

REST_FRAMEWORK = {
    # Use hyperlinked styles by default.
    # Only used if the `serializer_class` attribute is not set on a view.
    'DEFAULT_MODEL_SERIALIZER_CLASS':
        'rest_framework.serializers.HyperlinkedModelSerializer',

    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
    ]
}

Don't forget to make sure you've also added rest_framework to your INSTALLED_APPS setting.

That's it, we're done!
