Ruby on Rails

hi,

i' trying to re-create my project from php to rails. But now Im faced with a pb to witch I had solution with php, but I cant figure how to make it work with rails

here my tables

ads

  id

  category_id

  title

  text

ad_real_estate_details

  id

  ad_id

  nb_room

  floor

ad_car_details

  id

  ad_id

  color

  brand

here what I succeed to do

class Ad < ActiveRecord::Base

  attr_accessible :category_id :title, :text, :ad_real_estate_details

  has_one :ad_real_estate_details

  accepts_nested_attributes_for :ad_real_estate_details, allow_destroy: true

end

class AdRealEstateDetail < ActiveRecord::Base

  belongs_to :ad

  validates :ad_id, presence: true

end

but this only work for other category than real_estate

so I was thinking of polymorphism, but polymorphism mean I should add a reference in my "ad" table to the detail tables, and remove annonce_id from detail tables , what I thing is non-sense as some ads can have no details, but details are non-sense without an ad.

I was also thinking of a class AdDetails, and  AdRealEstateDetail would inherite from it, but this is not possible with rails as all subclasses will share the same table

does anyone have a solution for this kind of problem ?

thanks
