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

I think the following approach is more cleaner. You can set "abstract" field to true for the base serializer and add your common logic for all child serializers.

class TypeBaseSerializer(serializers.ModelSerializer):
    class Meta:
        model = TypeBase
        fields = ('id', 'name')
        abstract = True

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

And then create child serializers and use them for data manipulation.

class PersonTypeSerializer(TypeBaseSerializer):
    class Meta:
        model = PersonType
        fields = ('id', 'name')


class CompanyTypeSerializer(TypeBaseSerializer):
    class Meta:
        model = CompanyType
        fields = ('id', 'name')

Now you can use the both of these serializers normally for every model.

But if you really want to have one serializers for both the models, then create a container model and a serializer for him too. That is much cleaner :)
