Null Object Models is a gem that provides finder method(s) extensions to ActiveRecord::Base objects. These finder methods will return either default or defined null objects if an object is not found with the given ID(s). This is very useful for preventing nil errors. I recommend using this gem if you have dangling records and have yet to implement some sort of soft destroy implementation.
