• Easily and efficiently make your ActiveRecord models support hierarchies: https://github.com/mceachen/closure_tree

grandparent = Tag.create(name: 'Grandparent')
parent = grandparent.children.create(name: 'Parent')
child2 = Tag.new(name: 'Second Child')
parent.children << child2
d = Tag.find_or_create_by_path %w[a b c d]
h = Tag.find_or_create_by_path %w[e f g h]
e = h.root
d.add_child(e) # "d.children << e" would work too, of course
h.ancestry_path
=> ["a", "b", "c", "d", "e", "f", "g", "h"]
