Getting resource_name dynamically#935

I have the following structure of serializers

classA(Serializer)classJSONAPIMeta:resource_name="A"classB(Serializer)classJSONAPIMeta:resource_name="B"classMySerializer(Serializer)my_field=OneOfSerializer(A(),B())

OneOfSerializer is my custom serializer accepting values either forA orB. The main problem is that it doesn't containJSONAPIMeta and DRF-jsonapi raises an exception. Would it be possible to somehow return theresource_name dynamically based on the data, so that the relation is correctly set?

What version of DJA are you using? Since DJA version 4.0.0 nested serializers are not rendered as relationships anymore but as attribute value. So when I look at your example this would actually be rendered as attribute value instead and resource name is not needed in this case.

But if you wanna have dynamic relationships you can useSerializerMethodResourceRelatedField and the resource name is then calculated by the returning instance.

Does this help? Or have I misunderstood your question?

I'm using version 3.1.0.
Is theSerializerMethodResourceField going to work for serializer which is not tied to a model? I mean, I'm initializing it with custom data not necessarily being taken from django model. I'll try to experiment with that.

Yes it should work but give it a try.
