ActiveRecord in Rails 1.2.x has a method: serialize(attr_name, class_name = Object). I was wondering, given the new JSON serialization in 2.0, if it will be possible to request JSON instead of YAML when serializing data to a database column? Same goes for XML. It seems logical to modify the method to: serialize(column_name, options = {}). Then you could do something like: class User <

So I''ve got an ActiveRecord model pointing to a MySQL db, with an auto-serialized column ("serialize :columnName"). Thing is, MySQL, depending on how it''s configured (like, by default), has a bad habit of just truncating your data if it''s too wide for the column, with no error raised.
