STI hiding attributes
...,
email varchar(100) not null,
/* attributes for type = Customer */
balance decimal(10,2),
/* attributes for type = Employee */
reports_to int,
dept int,
/* attributes for type = Manager */
/* -- none -- */
)
class Person < ActiveRecord::Base
end
class Customer < Person
hides_attribute :reports_to, :dept
end
class Employee < Person
hides_attribute :balance
end
class Manager < Employee
hides_attribute :reports_to, :dept
end

object will no longer respond to reports_to, reports_to=, dept...
