This repository is a playground around various ways to handle prices with ActiveRecord.

Uses a decimal column to implement the price attribute.

Issue: price_before_type_cast will equal nil even if you pass a blank string, so you cannot rely on price_before_type_cast to provide a different treatment to a blank input if needed.

• composed_of (which was removed, then is back for now)
• custom accessors as advised on the commit that first removed composed_of
• money-rails (which implements a certain version of custom accessor)
