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'))
]
