How I can use Nested serializer in Django Rest Framework

Question

Hi I'm creating a serializer where I wanna show user profile details and all his products from the product model but it's not working

serializer.py

class UserSerializer(serializers.ModelSerializer):

related_products = ProductSerializer(
    source="user.product_set.all", read_only=True, many=True
)

class Meta:
    model = User
    fields = [
        "first_name",
        "last_name",
        "bio",
        "phone",
        "agency",
        "related_products",
    ]

views.py

class ProfileView(generics.RetrieveAPIView):
serializer_class = UserSerializer
permission_classes = [permissions.IsAuthenticated, onlyuser]

def retrieve(self, request, *args, **kwargs):
    serializer = self.serializer_class(request.user)
    return Response(serializer.data, status=status.HTTP_200_OK)

I found a solution if its a fine approach you can use it in your project

class ProfileView(generics.RetrieveAPIView):
def get(self, request, *args, **kwargs):

    qs = Product.objects.filter(user=request.user)
    data = {
        "user_profile": UserSerializer(request.user).data,
        "user_products": ProductSerializer(
            qs, many=True, context={"request": request}
        ).data,
    }
    return Response(data=data)
