Nested field serializer - Data missing

Question

Hi, I cannot follow the answer at the attached topic, because an ID is missing after serializat

Answer 1

Any AutoFields on your model (which is what the automatically generated id key is) are set to read-only by default when Django REST Framework is creating fields in the background. You can confirm this by doing

repr(CarSerializer())

and seeing the field generated with read_only=True set. You can override this with the extra_kwargs Meta option which will allow you to override it and set read_only=False.

class OwnerSerializer(serializers.ModelSerializer):

    class Meta:
        model =  Owner
        fields = ('id', 'name')
        extra_kwargs = {
            "id": {
                "read_only": False,
                "required": False,
            },
        }

This will include the id field in the validated_data when you need it.
