Change a field in a Django REST Framework ModelSerializer based on the request type?

Question

Consider this case where I have a Book and Author model.

serializers.py

class AuthorSerializer(serializers.ModelSerializer):

IMHO, multiple serializers are only going to create more and more confusion.

Rather I would prefer below solution:

1. Don't change your viewset (leave it default)
2. Add .validate() method in your serializer; along with other required .create or .update() etc. Here, real logic will go in validate() method. Where based on request type we will be creating validated_data dict as required by our serializer.

I think this is the cleanest approach.
