Rails - Jan 2006 - Multiple associations between tables - do they ever work?

This is really bugging me.  How can I get a second association to work 
between 2 tables.

I have two models, User and Article.  A user has many articles, and an 
article belongs to one user.  Then I have the "current article", which
is a the article that the user is currently viewing/editing.  I want to 
track/save this value, so they can come back to the same article if they 
log out and back in again.

The database tables are set up fairly basically, with user_id as a 
foreign key in the articles table, and current_article_id as a foreign 
key in the users table.

The model associations are defined as follows:

class User < ActiveRecord::Base
  has_many :articles, :order => "name", :dependent =>
:delete_all
  belongs_to :current_article, :class_name => "Article",
:foreign_key =>
"current_article_id"
end

class Article < ActiveRecord::Base
class Search < ActiveRecord::Base
  belongs_to :user
  has_one :current_for_user, :class_name =>"User", :foreign_key
=>
"current_article_id"
end

I simply cannot make the "current_article" association work reliably. 
Ideally, I want to be able to set the current article manually (when the 
user selects an existing article to edit or view), and also to set the 
current_article automatically (when a new article is created).

Has anyone managed to get something like this working?  If so, PLEASE 
share the details!

Ignore this line.  Cut and paste error.
