How do I use views in Django Rest Framework?

In Django Rest Framework, views are used to handle requests and return responses. You can create function-based views or class-based views. Would you like to see an example?

Yes, please provide an example of a class-based view.

Sure! Here's a simple example of a class-based view:

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

class HelloWorldView(APIView):
    def get(self, request):
        return Response({'message': 'Hello, World!'})

This view responds to GET requests with a JSON message.

How do I connect this view to a URL?

You can connect the view to a URL by adding it to your urls.py file like this:

from django.urls import path
from .views import HelloWorldView

urlpatterns = [
    path('hello/', HelloWorldView.as_view()),
]

What if I want to handle POST requests as well?

You can add a post method to your class-based view. Here's how:

class HelloWorldView(APIView):
    def get(self, request):
        return Response({'message': 'Hello, World!'})

    def post(self, request):
        data = request.data
        return Response({'received': data}, status=201)
