Django Rest Framework

 Django rest framework aka is very good framework form making API.

we can simply get the json format by using JsonResponse

from django.http import JsonResponse

return JsonResponse({key:value})

To install djangorest framework

simply do

pip install djangorestframework

json ----> python format is deserializaion

python format ====> json is serialization

from rest_framework.parsers import JSONParser

we can use JSONParser to parse json

serializer is used to validate data

from rest_framework.response import Response

we can use Response instead of JsonResponse

serializer=SerializerClass(queryset,many=True)

in deserialization

        serializer = Add2NumSerializer(data=data)

        if serializer.is_valid():

            n1 = serializer.validated_data['number1']

            n2 = serializer.validated_data['number2']

            result = n1+n2

            return Response({

                "result": result

            })

        print(serializer.errors)

        return Response({

            serializer.errors

        })

instead of above code we can simply do

        serializer = Add2NumSerializer(data=data)

        if serializer.is_valid(raise_exception=True):

            n1 = serializer.validated_data['number1']

            n2 = serializer.validated_data['number2']

            result = n1+n2

            return Response({

                "result": result

            })
