Serialize Model from Derived (Abstract) Model

问题

I have the following models:

class Address(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    ....
    class Meta:
        abstract = True

class BillingAddress(Address):
    is_default = models.BooleanField()
    ...
    class Meta:
        db_table = 'billing_address'

I'm trying to build a serializer for BillingAddress:

class AddressSerializer(serializers.ModelSerializer):
    class Meta:
        abstract = True
        model = AddressModel

class BillingAddressSerializer(AddressSerializer):
    def to_representation(self, obj):
        return AddressSerializer(obj, context=self.context).to_representation(obj)

    class Meta(AddressSerializer.Meta):
        model = UserBillingAddress
        fields = (
            'id',
            'is_default',
        )

I keep getting:

 ValueError: Cannot use ModelSerializer with Abstract Models.

How can I build my BillingAddressSerializer to reflect both classes?
