Sorry...I was incorrect about one thing. The Serializer is detecting
which columns are are flagged as serialized, however it will only
serialize them as YAML.
So say you have a Customer object, and serialized column called
favorite_products, which contains an array of product id's.....
You call Customer.find(1).to_xml, or Customer.find(1).to_json, you
respectively get an xml or json representation of that object, however
favorite_products will be yaml embedded in into the xml/json.....when
more often than not you'd want that to be xml or json as well.
