Remarks

Django REST Framework is a toolkit for building Web Apps. It helps the programmer to do REST APIs, but it can handle less mature API levels. For further information on API maturity levels, search for Richardson's Maturity Model.

In particular, Django REST Framework does not endorse any particular Hypermedia-level layout, and it is up to the programmer (or other projects, such as srf-hal-json) if they want to pursue a HATEOAS API implementation, to lay down their opinions outside of the framework. Thus, it is possible to implement a HATEOAS API in Django REST Framework, but there are no readily-available utilities already in place.

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'
    ]
}
 

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/ , 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.

Install or Setup

Requirements

  • Python (2.7, 3.2, 3.3, 3.4, 3.5, 3.6)
  • Django (1.7+, 1.8, 1.9, 1.10, 1.11)

Install

You can either use pip to install or clone the project from github.

  • Using pip :

    pip install djangorestframework
     
  • Using git clone :

    git clone [email protected]:tomchristie/django-rest-framework.git
     

After installing, you need to add rest_framework to your INSTALLED_APPS settings.

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'))
]
