Hi,

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](http://foo.com/articles/3) and a  
user exists at [http://bar.com/users/1](http://bar.com/users/1), If would like to be able to do  
from [http://foo.com](http://foo.com) web interface or [http://bar.com](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  
has\_and\_belongs\_to\_many :users  
end

Is there yet some example of project using this kind of relation over  
internet?

Many thanks
