Answer 1

Override the to_representation() method in your serializer to customize the response when sending back to the view/controller. instance is the object of the serializing model.

    def to_representation(self, instance):
        ret = super().to_representation(instance)
        ret["country"] = instance.country.name if country else None
        return ret
