Django REST Framework

Attention

This a non-official Sphinx version of the Django REST Framework’s documentation, mantained by Martín Gaitán

As the official documentation is written using Markdown and custom scripts, it can’t be rendered using Sphinx nor take advantage of Read the Docs’s downloads in many formats.

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:

Requirements

REST framework requires the following:

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

The following packages are optional:

Markdown <http://pypi.python.org/pypi/Markdown/>`_ (2.1.0+)
Markdown support for the browsable API.
PyYAML <http://pypi.python.org/pypi/PyYAML>`_ (3.10+)
YAML content-type support.
defusedxml <https://pypi.python.org/pypi/defusedxml>`_ (0.3+)
XML content-type support.
django-filter <http://pypi.python.org/pypi/django-filter>`_ (0.5.4+)
Filtering support.
django-oauth-plus <https://bitbucket.org/david/django-oauth-plus/wiki/Home>`_ (2.0+) and oauth2 (1.5.211+)
OAuth 1.0a support.
django-oauth2-provider <https://github.com/caffeinehit/django-oauth2-provider>`_ (0.2.3+)
OAuth 2.0 support.
django-guardian <https://github.com/lukaszb/django-guardian>` (1.1.1+)
Object level permissions 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 browsable API.
pip install django-filter  # Filtering support

...or clone the project from github.

git clone git@github.com:tomchristie/django-rest-framework.git

Add 'rest_framework' to your INSTALLED_APPS setting.

INSTALLED_APPS = (
    ...
    'rest_framework',
)

If you’re intending to use the browsable 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.

Any global settings for a REST framework API are kept in a single configuration dictionary named REST_FRAMEWORK. Start off by adding 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.

We’re ready to create our API now. Here’s our project’s root urls.py module:

from django.conf.urls 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'))
)

Quickstart

Can’t wait to get started? The quickstart guide 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.

There is a live example API of the finished tutorial API for testing purposes, available here.

API Guide

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

Development

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

Run the tests:

./rest_framework/runtests/runtests.py

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

tox

Support

For support please see the REST framework discussion group, try the #restframework channel on irc.freenode.net, search the IRC archives, or raise a question on Stack Overflow, making sure to include the ‘django-rest-framework’ tag.

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

Security

If you believe you’ve found something in Django REST framework which has security implications, please do not raise the issue in a public forum.

Send a description of the issue via email to rest-framework-security@googlegroups.com. The project maintainers will then work with you to resolve any issues where required, prior to any public disclosure.
