        With this mix-in, you can have nice "to_hash" methods on your active record objects.  

I find it good for programming JSON apps.

In lib/ar_hashing.rb

module ActiveRecordHashing
  def to_hash
      Hash[*self.map{ |m| [m.id, m]}.flatten]               
  end
end


and in config/environment.rb

require 'ar_hashing'

class ActiveRecord::Associations::AssociationCollection
  include ActiveRecordHashing
end

This didn't work for me, but I just used ActiveRecord's `attributes` method
