My guess is you want to call marshallable! on the instance first: model_instance.marshallable!.to_yaml Unlike the json_serializer or xml_serializer plugins, dumping as yaml is similar to dumping as marshal, in that it just takes the instance variables as dumps them. Sequel::Model instances often contain instances of objects that have been extended with a module and therefore cannot be marshalled. Calling marshallable! removes the stuff that can't be marshalled, so you should be able to call to_yaml on the resulting instance.
