The document introduces Django REST framework, which makes it easy to build web APIs. It includes serializers to convert data to and from JSON/XML, an API browser, and security features out of the box. Serializers define how models are exposed in the API. Views provide endpoints and connect models and serializers. Routers automatically generate URLs and handle requests to the views. The framework handles common tasks like validation and HTTP status codes so APIs can be built quickly.

HOW IT WORKS: SERIALIZERS from django.contrib.auth.models import User, Group from rest_framework import serializers class UserSerializer(serializers.HyperlinkedModelSerializer):     class Meta:         model = User         fields = ('url', 'username', 'email', 'groups') class GroupSerializer(serializers.HyperlinkedModelSerializer):     class Meta:         model = Group         fields = ('url', 'name')
HOW IT WORKS: VIEWS from django.contrib.auth.models import User, Group from rest_framework import viewsets from quickstart.serializers import UserSerializer, GroupSerializer class UserViewSet(viewsets.ModelViewSet):     """API endpoint that allows users to be viewed or edited."""     queryset = User.objects.all()     serializer_class = UserSerializer class GroupViewSet(viewsets.ModelViewSet):     """API endpoint that allows groups to be viewed or edited."""     queryset = Group.objects.all()     serializer_class = GroupSerializer
HOW IT WORKS: ROUTER from django.conf.urls import url, include from rest_framework import routers from tutorial.quickstart import views router = routers.DefaultRouter() router.register(r'users', views.UserViewSet) router.register(r'groups', views.GroupViewSet) # 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'^api­auth/', include('rest_framework.urls')) ]
DONE. (Demo)
