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

	// A simple module to replace `Backbone.sync` with localStorage-based
	// persistence. Models are given GUIDS, and saved into a JSON object. Simple
	// as that.

	// Generate four random hex digits.
	function S4() {
	return (((1+Math.random())*0x10000)\|0).toString(16).substring(1);
	};

	// Generate a pseudo-GUID by concatenating random hexadecimal.
