Has_one and Class Table Inheritance


Hello, is there something wrong with using has_one to implement Class
Table Inheritance ?


class Person < ActiveRecord::Base

attributes : eg. name, string


class Contact < Person

attributes :

has_one :Person
belongs_to :Company

Of course for a such simple case I could use Single Table Inheritance
but this is only an example and I don’t like too much the fact of mixing
in a single table a bunch of inrelated and unused properties.

Your advice is welcome, thanks
