= Has(AndBelongsTo)ManyRelated

Has(AndBelongsTo)ManyRelated is Rails plugin that associates a class with itself 
via an intermediate join table, extending the original has_and_belongs_to_many 
with symmetric associations. 

== Installation

Install it into your Rails project via script/plugin:

 script/plugin install http://hasmanyrelated.rubyforge.org/svn/trunk/has_many_related

== Example

Assuming you have a join table with columns "user_id" and "friend_id":

 class User < ActiveRecord::Base
   has_many_related :friends, :foreign_key => 'friend_id'
 end

Let's create some users:

 jan = User.create
 marc = User.create

Association is symmetric, so if Marc is Jan's friend, Jan is Marc's friend too:

 jan.friends << marc
 marc.friends.include? jan # true
 
 marc.friends.clear
 jan.friends.include? marc # false
