1. Add 10gen package to source.list.d
Ubuntu 12 comes with a “mongo” package, but not the latest version.

$ sudo apt-cache search mongodb
mongodb
mongodb-clients
mongodb-dev
mongodb-server
It’s recommended to add 10gen package to /etc/apt/sources.list.d, as it contains the latest stable MongoDB. Create a /etc/apt/sources.list.d/mongo.list file, and declared the 10gen distro.

In this article, I'll walk through a basic Rails (3.2.x) setup for creating a nested resource for two models. Nested resources work well when you want to build out URL structure between two related models, and still maintain a RESTful convention. This code assumes you are running RVM to manage Ruby/Gem versions, and Git for version control.

Creating a new Rails project

$ mkdir family # create rvm gemset 
$ echo "rvm use --create ruby-1.9.2@family" > family/.rvmrc 
$ cd family # install rails 
$ gem install rails # create new rails project 
$ rails new . # version control

<% flash.each do |type, message| %>
  <div class="alert <%= bootstrap_class_for(type) %> fade in">
    <button class="close" data-dismiss="alert">×</button>
    <%= message %>
  </div>
<% end %>

UPDATE: It's a gem!

This helper has finally been moved into a gem called nav_lynx!

http://rubygems.org/gems/nav_lynx

Thanks to @brianjlandau and @reagent for getting that set up and tested!

Behold, the nav_link:
