Django REST framework

A toolkit for building well-connected, self-describing Web APIs.

Django REST framework is a lightweight library that makes it 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 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.

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 (2.1.0+) - Markdown support for the browseable API.
• PyYAML (3.10+) - YAML content-type support.
• defusedxml (0.3+) - XML content-type support.
• django-filter (0.5.4+) - Filtering support.

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.
