django rest framework abstract class serializer

Question

I have some models like these:

class TypeBase(models.Model):
    name = models.CharField(max_length=20)
    class Meta:
        abstract=True

class PersonType(T         


        

Answer 1

Just iterating a bit over @adki's answer:

1. it is possible to skip model for TypeBaseSerializer;
2. derived serializers can refer to TypeBaseSerializer.Meta, so you would change them in a single place.

class TypeBaseSerializer(serializers.Serializer):
    class Meta:
        fields = ('id', 'name', 'created')
        abstract = True

    def func(...):
    # ... some logic

class PersonTypeSerializer(TypeBaseSerializer):
    class Meta:
        model = PersonType
        fields = TypeBaseSerializer.Meta.fields + ('age', 'date_of_birth')

class CompanyTypeSerializer(TypeBaseSerializer):
    class Meta:
        model = CompanyType
        fields = TypeBaseSerializer.Meta.fields
