The serialization and deserialization happen at the model layer, so if you use naked to skip the model layer, you skip the deserialization. Also, Model#to_hash just returns the column values (serialized), it doesn't include the deserialized values. You may want: dataset.all.map do |v| hash = v.values.dup hash[:transaction_data] = v.transaction_data hash[:other_attributes] = v.other_attributes hash end Thanks, Jeremy -- You received this message because you are subscribed to the Google Groups "sequel-talk" group.
