Django REST framework is a powerful and flexible toolkit for building Web APIs.

Some reasons you might want to use REST framework:

* The [Web browsable API][sandbox] is a huge usability win for your developers.
* [Authentication policies][authentication] including packages for [OAuth1a][oauth1-section] and [OAuth2][oauth2-section].
* [Serialization][serializers] that supports both [ORM][modelserializer-section] and [non-ORM][serializer-section] data sources.
* Customizable all the way down - just use [regular function-based views][functionview-section] if you don't need the [more][generic-views] [powerful][viewsets] [features][routers].
* [Extensive documentation][index], and [great community support][group].
* Used and trusted by internationally recognised companies including [Mozilla][mozilla], [Red Hat][redhat], [Heroku][heroku], and [Eventbrite][eventbrite].

---

## Funding

REST framework is a *collaboratively funded project*. If you use
REST framework commercially we strongly encourage you to invest in its
continued development by **[signing up for a paid plan][funding]**.

The initial aim is to provide a single full-time position on REST framework.
*Every single sign-up makes a significant impact towards making that possible.*

## Requirements

REST framework requires the following:

* Python (2.7, 3.2, 3.3, 3.4, 3.5)
* Django (1.8, 1.9, 1.10)

The following packages are optional:

* [coreapi][coreapi] (1.32.0+) - Schema generation support.
* [Markdown][markdown] (2.1.0+) - Markdown support for the browsable API.
* [django-filter][django-filter] (0.9.2+) - Filtering support.
* [django-crispy-forms][django-crispy-forms] - Improved HTML display for filtering.
* [django-guardian][django-guardian] (1.1.1+) - Object level permissions support.

## 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 = [
        ...
        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. You may leave out the namespace in Django 1.9+, and REST framework will set it for you.

## 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 information on the users of our project.

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 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, include
    from django.contrib.auth.models import User
    from rest_framework import routers, serializers, viewsets

	# Serializers define the API representation.
	class UserSerializer(serializers.HyperlinkedModelSerializer):
	    class Meta:
	        model = User
	        fields = ('url', 'username', 'email', 'is_staff')

    # ViewSets define the view behavior.
    class UserViewSet(viewsets.ModelViewSet):
        queryset = User.objects.all()
        serializer_class = UserSerializer

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

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

You can now open the API in your browser at [http://127.0.0.1:8000/](http://127.0.0.1:8000/), and view your new 'users' API. If you use the login control in the top right corner you'll also be able to add, create and delete users from the system.

## 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]
* [6 - Viewsets & routers][tut-6]
* [7 - Schemas & client libraries][tut-7]

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