Below are my urls.py I need to Specify the structure of the payload and Specify headers in every request

    from django.conf.urls import url, include

    from rest_framework.routers import DefaultRouter

    from . import views



    router = DefaultRouter()



    router.register("patient", views.PatientsApiView)



    urlpatterns = [

        url(r'', include(router.urls))



     ]

Below are my views.py
I have made 1 view with model viewset and the other with the generic API view

class PatientsApiView(viewsets.ModelViewSet):

    model = Patient

    fields = ("id",  "first_name", "last_name", "phone", "email", "created_at")



"""

Create a serializer in serializer.py



class EmbryoSerializer(serializers.ModelSerializer):

    class Meta:

        model = Embryo

        fields = ("id", "name", "analysis_result", "created_at", "patient")



"""



class EmbryoApiView(APIView):

    def get(self, request, format=None):

        embryo = Embryo.objects.all()

        serializer = EmbryoSerializer(embryo, many=True)

        return Response(serializer.data)



    def post(self, request, format=None):

        serializer = EmbryoSerializer(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)



    def put(self, request, pk, format=None):

        embryo = self.get_object(pk)

        serializer = EmbryoSerializer(embryo, data=request.data)

        if serializer.is_valid():

            serializer.save()

            return Response(serializer.data)

        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)



    def patch(self, request, user_id):

        user = User.objects.get(id=user_id)

        serializer = EmbryoSerializer(embryo, data=request.data, partial=True)

        if serializer.is_valid():

            serializer.save()

            return Response(serializer.data)

        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

router.register("embryo", views.EmbroApiView)

How do you think I can achieve this in my views.py

Specifying the structure of the payload and headers for every request is best done in views.py and serializers.py

Payload will be validated in serializers . Headers you can simply pass to Response().
For instance
return Response( … , headers={'My-Header': 'hello'}) will add the header.

example:

class EmbryoApiView(APIView):

    def get(self, request, format=None):

        embryo = Embryo.objects.all()

        serializer = EmbryoSerializer(embryo, many=True)

        return Response(serializer.data, headers={'My-Header': 'Below are all the embroys for this patient'})
