**Awesome web-browsable Web APIs.**
|
||
|
||
Full documentation for the project is available at [http://www.django-rest-framework.org][docs].
|
||

|
||
|
||
**Note**: We have now released Django REST framework 3.3. For older codebases you may want to refer to the version 2.4.4 [source code][2.4-code], and [documentation][2.4-docs].
|
||
|
||
For more details see the 3.3 [announcement][3.3-announcement] and [release notes][3.3-release-notes].

# Overview
|
||
|
||
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 optional 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][docs], and [great community support][group].
|
||
|
||
There is a live example API for testing purposes, [available here][sandbox].

# Requirements
|
||
|
||
* Python (2.7, 3.2, 3.3, 3.4, 3.5)
|
||
* Django (1.7, 1.8, 1.9)
|
||
|
||
# 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.
|
||
|
||
Startup up a new project like so...
|
||
|
||
pip install django
|
||
pip install djangorestframework
|
||
django-admin.py startproject example .
|
||
./manage.py migrate
|
||
./manage.py createsuperuser
|
||
|
||
|
||
Now edit the `example/urls.py` module in your project:
|
||
|
||
```python
|
||
from django.conf.urls import url, include
|
||
from django.contrib.auth.models import User
|
||
from rest_framework import serializers, viewsets, routers
|
||
|
||
# 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 a 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'))
|
||
]
|
||
```
|
||
|
||
We'd also like to configure a couple of settings for our API.
|
||
|
||
Add the following to your `settings.py` module:
|
||
|
||
```python
|
||
INSTALLED_APPS = (
|
||
... # Make sure to include the default installed apps here.
|
||
'rest_framework',
|
||
)
|
||
|
||
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'
|
||
]
|
||
}
|
||
```
|
||
|
||
That's it, we're done!
|
||
|
||
./manage.py runserver
|
||
|
||
You can now open the API in your browser at `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.
|
||
|
||
You can also interact with the API using command line tools such as [`curl`](http://curl.haxx.se/). For example, to list the users endpoint:
|
||
|
||
$ curl -H 'Accept: application/json; indent=4' -u admin:password http://127.0.0.1:8000/users/
|
||
[
|
||
{
|
||
"url": "http://127.0.0.1:8000/users/1/",
|
||
"username": "admin",
|
||
"email": "admin@example.com",
|
||
"is_staff": true,
|
||
}
|
||
]
|
||
|
||
Or to create a new user:
|
||
|
||
$ curl -X POST -d username=new -d email=new@example.com -d is_staff=false -H 'Accept: application/json; indent=4' -u admin:password http://127.0.0.1:8000/users/
|
||
{
|
||
"url": "http://127.0.0.1:8000/users/2/",
|
||
"username": "new",
|
||
"email": "new@example.com",
|
||
"is_staff": false,
|
||
}
|
||
|
||
