Return different serializer after create() in CreateAPIView in Django REST Framework

Change CreateOrderView as below,

class CreateOrderView(generics.CreateAPIView):
    serializer_class = OrderCreateSerializer

    def perform_create(self, serializer):
        return serializer.save(user=self.request.user)

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        instance = self.perform_create(serializer)
        instance_serializer = OrderListSerializer(instance)
        return Response(instance_serializer.data)

serializer.save() returns the instance that just created or updated. So we use that istance to pass to the OrderListSerializer and returning the corresponding response.
