I have a has and belongs to many relation between User and Article
models, and I would like to link them even if an article if not hosted
on the same database then a user.
For example, If an article exists at http://foo.com/articles/3 and a
user exists at http://bar.com/users/1, If would like to be able to do
from http://foo.com web interface or http://bar.com web interface this
kind of query: a_user.articles (or an_article.users).
I think this can be possible adding a field like "url" in users and
articles tables. But I don't know how to process for ActiveRecord. My
Article model looks like this:
class Article < ActiveRecord::Base
Is there yet some example of project using this kind of relation over
