Looks like the html in my last comment did not get encoded correctly. Here it is again:

You can also use the excellent nested_has_many_through plugin.
http://github.com/ianwhite/nested_has_many_through

That will allow you to do

class State < ActiveRecord::Base
has_many :cities
has_many :houses, :through => :cities
end

>> virginia.houses

I’ve been using it in a big app for over a year. Wish it was included in rails core already.
