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 =>

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

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!
