Has_many :addresses, :as => :addressable

I just got the Rails Recipies and I’m looking the Recipe 17.

class Person < ActiveRecord::Base
has_many :addresses, :as => :addressable
end

class Company < ActiveRecord::Base
has_many :addresses, :as => :addressable
end

class Address < ActiveRecord::Base
belongs_to :addressable, :polymorphic => true
end

At the beggining I had some problems because “polymorphic” was not
supported on Rails1.0.0 then I update rails. In the console everything
works fine but when I’m trying to list the people I’m getting the
“Unknown key(s): as” error.
Does anyone have a clue of what’s going on?


This is what I have updated

Seems broken. I get:

Company.find(1).create_address
NoMethodError: undefined method `create_address’

It’s working great if i’m using:
has_one :address, :as => :addressable
