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, 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]**.
*Every single sign-up helps us make REST framework long-term financially sustainable.*
*Many thanks to all our [wonderful sponsors][sponsors], and in particular to our premium backers, [Sentry](https://getsentry.com/welcome/), [Stream](https://getstream.io/?utm_source=DjangoRESTFramework&utm_medium=Webpage_Logo_Ad&utm_content=Developer&utm_campaign=DjangoRESTFramework_Jan2022_HomePage), [Spacinov](https://www.spacinov.com/), [Retool](https://retool.com/?utm_source=djangorest&utm_medium=sponsorship), [bit.io](https://bit.io/jobs?utm_source=DRF&utm_medium=sponsor&utm_campaign=DRF_sponsorship), [PostHog](https://posthog.com?utm_source=DRF&utm_medium=sponsor&utm_campaign=DRF_sponsorship), [CryptAPI](https://cryptapi.io), and [FEZTO](https://www.fezto.xyz/?utm_source=DjangoRESTFramework).*

## Requirements
REST framework requires the following:
* Python (3.6, 3.7, 3.8, 3.9, 3.10, 3.11)
* Django (3.0, 3.1, 3.2, 4.0, 4.1)
We **highly recommend** and only officially support the latest patch release of
each Python and Django series.
The following packages are optional:
* [PyYAML][pyyaml], [uritemplate][uriteemplate] (5.1+, 3.0.0+) - Schema generation support.
* [Markdown][markdown] (3.0.0+) - Markdown support for the browsable API.
* [Pygments][pygments] (2.4.0+) - Add syntax highlighting to Markdown processing.
* [django-filter][django-filter] (1.0.1+) - Filtering support.
* [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 https://github.com/encode/django-rest-framework
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 = [
...
path('api-auth/', include('rest_framework.urls'))
]
Note that the URL path can be whatever you want.
## 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.urls import path, 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 = [
path('', include(router.urls)),
path('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.
## Development
See the [Contribution guidelines][contributing] for information on how to clone
the repository, run the test suite and contribute changes back to REST
Framework.
## Support
For support please see the [REST framework discussion group][group], try the `#restframework` channel on `irc.libera.chat`, or raise a question on [Stack Overflow][stack-overflow], making sure to include the ['django-rest-framework'][django-rest-framework-tag] tag.
For priority support please sign up for a [professional or premium sponsorship plan](https://fund.django-rest-framework.org/topics/funding/).
