How do add a non-model field on a ModelSerializer in DRF 3? i.e. add a field that does not exist on my actual model?
class TestSerializer(serializers.ModelSerializer): url = serializers.HyperlinkedIdentityField(view_name='vote_detail') non_field = serializers.CharField() # no corresponding model property. class Meta: model = vote_model fields = ("url", "non_field") def create(self, validated_data): print(direction=validated_data['non_field'])
But DRF 3 gives me the error:
Got AttributeError when attempting to get a value for field `non_field` on serializer `TestSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `Test` instance. Original exception text was: 'Test' object has no attribute 'non_field'.
I have searched stack DRF – ModelSerializer with a non-model write_only field and found a few solutions but these refer to DRF 2 where I'm using DRF 3. Is there a solution for this on this version?
