# 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.*

# 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 (3.6, 3.7, 3.8, 3.9, 3.10)
|
|
* Django (2.2, 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.
|
|
|
|
# Installation
|
|
|
|
Install using `pip`...
|
|
|
|
pip install djangorestframework
|
|
|
|
Add `'rest_framework'` to your `INSTALLED_APPS` setting.
|
|
```python
|
|
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 startproject example .
|
|
./manage.py migrate
|
|
./manage.py createsuperuser
|
|
|
|
|
|
Now edit the `example/urls.py` module in your project:
|
|
|
|
```python
|
|
from django.urls import path, 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 = [
|
|
path('', include(router.urls)),
|
|
path('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`](https://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,
|
|
}
|
|
