You can ask me something.

• ActiveRecord is pretty smart sometimes. Self-referential has_many relations are totally possible, and rails builds a pretty query to do it.

  Check it:

  class Nose < ActiveRecord::Base
    has_many :similar_noses, :class => 'Nose', :foreign_key => 'nose_type', :primary_key => 'nose_type'
  end
  
  crooked_nose = Nose.find_by_name('Crooked')
  crookeds = crooked_nose.similar_noses
  # SQL: SELECT * FROM noses WHERE nose_type = 'crooked_kind_of_nose'
  
  crookeds.collect{|nose| nose.name }
  # => ['Armenian', 'Polish', 'Broken', 'Crooked']
