# If you use amoeba (https://github.com/amoeba-rb/amoeba) for cloning your
# ActiveRecord objects this concern should be useful, it allows you properfly inherit
# associations if you use (Single Table) Inheritance.
#
# Just do something like:
# 
# class SomeTable < ActiveRecord::Base
#   has_many :somethings
#
#   duplicate_this do
