hstore_accessor | Adds typed hstore-backed field support | Application Framework library

Add this line to your application's Gemfile:.
The hstore_accessor method accepts the name of the hstore column you'd like to use and a hash with keys representing fields and values indicating the type to be stored in that field. The available types are: string, integer, float, decimal, datetime, date, boolean, array, and hash. It is available on an class that inherits from ActiveRecord::Base. Now you can interact with the fields stored in the hstore directly. Reading these fields works as well. In order to reduce the storage overhead of hstore keys (especially when indexed) you can specify an alternate key. In the above example you can continue to interact with the fields using their full name but when saved to the database the field will be set using the store_key. Additionally, dirty tracking is implemented in the same way that normal ActiveRecord fields work.
