Django Rest Framework's APIView: Examples and Usage

Creating a Basic APIView:

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

class MyAPIView(APIView):
    def get(self, request):
        data = {'message': 'Hello, APIView!'}
        return Response(data, status=status.HTTP_200_OK)

Output:

{"message": "Hello, APIView!"}

2. Handling POST Requests:

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

class MyAPIView(APIView):
    def post(self, request):
        # Handle POST data and perform actions
        data = {'message': 'POST request received successfully'}
        return Response(data, status=status.HTTP_201_CREATED)

Output:

{"message": "POST request received successfully"}

3. Handling URL Parameters:

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

class MyAPIView(APIView):
    def get(self, request, pk):
        # Use 'pk' to fetch data related to a specific resource
        data = {'resource_id': pk, 'message': 'Resource details fetched successfully'}
        return Response(data, status=status.HTTP_200_OK)

Output:

{"resource_id": "1", "message": "Resource details fetched successfully"}

4. Handling PUT and DELETE Requests:

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

class MyAPIView(APIView):
    def put(self, request, pk):
        # Handle PUT request to update a resource
        data = {'message': f'Resource {pk} updated successfully'}
        return Response(data, status=status.HTTP_200_OK)

    def delete(self, request, pk):
        # Handle DELETE request to delete a resource
        data = {'message': f'Resource {pk} deleted successfully'}
        return Response(data, status=status.HTTP_204_NO_CONTENT)

Output (PUT Request):

{"message": "Resource 1 updated successfully"}

Output (DELETE Request):

{"message": "Resource 1 deleted successfully"}

Authentication and Permissions:

from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
from rest_framework.permissions import IsAuthenticated
from rest_framework.authentication import TokenAuthentication

class MySecuredAPIView(APIView):
    authentication_classes = [TokenAuthentication]
    permission_classes = [IsAuthenticated]

    def get(self, request):
        data = {'message': 'Authenticated and authorized access'}
        return Response(data, status=status.HTTP_200_OK)

Output:

{"message": "Authenticated and authorized access"}
