Active Record to_hash

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
