Last active December 18, 2015 17:59
This example demonstrates how to incrementally load and save object graphs using Backbone-associations. This is important because rarely, there would be a need to fetch (or save) a entire object hierarchy from the server.
var MyApp = {
context: {}
};
MyApp.context.departments = null;
MyApp.context.employees = null;
var counter = 100;

RequireJS shim to use Backbone-associations.js.
require.config({
paths: {
'jquery': 'vendor/jquery',
// -----------------------------------
// Use AMD versions of Backbone/Underscore : https://github.com/amdjs
'underscore': 'vendor/underscore-amd',
'backbone': 'vendor/backbone-amd',
// -----------------------------------
'backbone-associations': 'vendor/backbone-associations'
},
