The guts of a page tree using slugs - acts_as_tree, friendly_id - Allows for routes like /about/our-people/developers

Gemfile

gem 'acts_as_tree'
gem "friendly_id", "~> 4.0.1"

page.rb

class Page < ActiveRecord::Base
  acts_as_tree

  extend FriendlyId
  friendly_id :title, :use => :scoped, :scope => :parent

  before_save :compute_path

  def compute_path
    self.path = ancestors.reverse.push(self).collect(&:slug).join("/")
  end

end


# == Schema Information
#
# Table name: pages
#
#  id         :integer         not null, primary key
#  title      :string(255)
#  creator_id :integer
#  content    :text
#  parent_id  :integer
#  position   :integer
#  path       :string(255)
#  slug       :string(255)
#  created_at :datetime        not null
#  updated_at :datetime        not null
#

pages_controller.rb

class PagesController < ApplicationController

  def show
    @page = Page.find_by_path(params[:path])
  end

end

routes.rb

Whatever::Application.routes.draw do

  # every other route...

  match "*path", :to => "pages#show"

end

Nice!

Useful. Thanks!
