I should point out that if you aren't using PostgreSQL, you can use the serialization plugin as you are doing currently, and the code below will work. Basically, your issue is you are keeping track of the data in two separate places (instance variables and the deserialized json hash), instead of a single place. If you just keep track of it in a single place, as the code below does, you are fine, assuming you aren't actually modifying attr1 or attr2 during the call to save.
