How to create an ActiveRecord relation to an ActiveResource object?

Question

Say I'm writing a library application for a publishing company that already has a People application.

So in my Library application I have

class Person < ActiveResource::Base
  self.site = "http://api.people.mypublisher.com/"
end

and now I want to save Articlefor each Person:

class Article < ActiveRecord::Base
  belongs_to :person, :as => :author
end

I assume that I will have the following table in my database:

Articles
id (PK) | title (string) | body (text) | author_id (integer)

author_id- This is not a foreign key, since I do not have a People table. This leaves a few questions:

• How can I tell my object Person ActiveResourcethat it is has_many Articles?

• Will it work Articles.find(:first).author? Will it work belongs_toprovided that there is no ActiveRecordand no support table?
