HABTM association with own class?

Dave, with a web site with that name I am sure Josh knows a lot more about this than I do, but in the case you describe it looks like you just want a simple self-join. In which case I think what you want is:

def Asset < ActiveRecord::Base   has_and_belongs_to_many :related_assets,     :class_name => "Article",     :join_table => "related_assets",     :association_foreign_key => "related_asset_id",     :foreign_key => "asset_id" end

And then a table called related_assets with the columns related_asset_id and asset_id
