Overview

The heart of StoreConfigurable’s data store is this subclass of ActiveSupport’s OrderedOptions. They are the heart of Rails’ configurations and allow you to dynamically set and get hash keys and values using dot property notation vs the [] hash accessors.

However, instances of DirtyTrackingOrderedOptions use a recursive lambda via Hash’s block initialization syntax so that you get a dynamic and endless scope on config data. Instances of DirtyTrackingOrderedOptions also make sure that every sub instance of it self also has a handle back to your store’s owner. In this way when config attributes are added or values change, we can mark your ActiveRecord object as dirty/changed.
