Class Table Inheritance in Rails 3

Question

I\'m currently working on a Rails 3 application that looks like it might need to use Class Table Inheritance for a couple of models.

A simplified example of what\'s goin

Answer 1

Also there is a plugin 'acts_as_relation' to do this,
https://github.com/hzamani/acts_as_relation/

in your case the code will be this:

class Driver < ActiveRecord::Base
   acts_as :person
end

class Passenger < ActiveRecord::Base
  acts_as :person
end

Don't forget to add person_type and person_id columns to persons table.
Now both Drive and Passenger inherit Person attributes, validations and methods.
