I modified your copy method slightly to allow passing in a hash of attribute values that will override the copied values. This also allows on-the-spot overrides of the non_duplicatable_columns. def copy(overrides = {}) copy_columns = self.class.column_names - self.class.non_duplicatable_columns a = Hash.new copy_columns.each {|cc| a[cc.to_sym] = self.send(cc) } clone = self.class.create(a.merge(overrides)) end This was a very helpful post – thanks!

def copy(overrides = {})
copy_columns = self.class.column_names – self.class.non_duplicatable_columns
a = Hash.new
copy_columns.each {|cc| a[cc.to_sym] = self.send(cc) }
clone = self.class.create(a.merge(overrides))
