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

Some reasons you might want to use REST framework:

REST framework requires the following:

The following packages are optional:

Install using pip,including any optional packages you want...

...or clone the project from github.

Add 'rest_framework' to your INSTALLED_APPS setting.

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.

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.

<a class="toclink" href="http://www.django-rest-framework.org/#example"&gt;快速上手实例

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:

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:

class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = User
fields = ('url','username','email','is_staff')

class UserViewSet(viewsets.ModelViewSet):
queryset = User.objects.all()
serializer_class = UserSerializer

router = routers.DefaultRouter()
router.register(r'users',UserViewSet)

urlpatterns = [
url(r'^',include(router.urls)),url(r'^api-auth/',namespace='rest_framework'))
]

You can now open the API in your browser at ,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.
