README.md

I have a Rails 3 application; we can consider it a blog system. All content is stored in Nodes. I am using a specifically tailored route to allow Nodes to have clean URLs.

= form_for [:admin, @node] do                        # => generated URL is /admin/nodes or /admin/nodes/4d1a44571d41c821eb000006
= link_to 'all nodes', nodes_path                    # => generated URL is /
= link_to @node.title, node_path(@node.to_path)      # => generated URL is /about or /about/people or /4d1a44571d41c821eb000006
= link_to 'all nodes (admin view)', admin_nodes_path # => generated URL is /admin/nodes
= link_to 'add', new_admin_node_path                 # => generated URL is /admin/nodes/new
= link_to 'edit', edit_admin_node(@node)             # => generated URL is /admin/nodes/4d1a44571d41c821eb000006/edit
= link_to 'delete', [:admin, @node], :confirm => 'Are you sure?', :method => :delete
                                                     # => generated URL is /admin/nodes/4d1a44571d41c821eb000006

node.rb

class Node
  include MongoMapper::Document

  key :path, String, :unique => true
  key :title, String, :required => true

  def to_path
    path.to_s.blank? ? _id.to_s : path
  end

  def self.from_path(path)
    return nil if path.nil? || path.blank?
    reply = first :path => path
    reply = find path unless reply.present?
    reply
  end
end

routes.rb

Blog::Application.routes.draw do
  resources :nodes, :only => :index, :show

  namespace :admin do
    resources :nodes, :except => :show
  end

  get '/*id_or_path', :to => 'nodes#show', :as => :node

  root :to => 'nodes#index'
end
