Views & Routing

ModelViewSet (Full CRUD)

from rest_framework import viewsets
from .models import Post
from .serializers import PostSerializer

class PostViewSet(viewsets.ModelViewSet):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

APIView (Manual Control)

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status

class PostList(APIView):
    def get(self, request):
        posts = Post.objects.all()
        serializer = PostSerializer(posts, many=True)
        return Response(serializer.data)

    def post(self, request):
        serializer = PostSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

Generic Views

from rest_framework import generics

class PostListCreate(generics.ListCreateAPIView):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

class PostDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

Custom Actions in ViewSet

from rest_framework.decorators import action

class PostViewSet(viewsets.ModelViewSet):
    @action(detail=True, methods=['post'])
    def publish(self, request, pk=None):
        post = self.get_object()
        post.publish()
        return Response({'status': 'published'})

Default Router

from rest_framework.routers import DefaultRouter
from .views import PostViewSet

router = DefaultRouter()
router.register(r'posts', PostViewSet, basename='post')

urlpatterns = [
    path('', include(router.urls)),
]

Manual URL Patterns

urlpatterns = [
    path('posts/', views.PostList.as_view()),
    path('posts/<int:pk>/', views.PostDetail.as_view()),
]

Dynamic Serializer Class

class PostViewSet(viewsets.ModelViewSet):
    def get_serializer_class(self):
        if self.action == 'list':
            return PostListSerializer
        return PostDetailSerializer
