dylants / authenticated-model.js

Created January 7, 2014 17:39

A Backbone Model which provides a hook to handle unauthorized API requests to the server. When dealing with server side security, this is one way of handling an unauthorized user on the client side in a generic way. By extending this model rather than Backbone's model, you can decide what should happen to the user when they hit an unauthorized r…

	/* global define:true */
	define([
	"backbone"
	], function(Backbone) {
	"use strict";

	// Extend Backbone's Model to override the sync function. Doing so allows us
	// to get a hook into how the errors are handled. Here we can check if the
	// response code is unauthorized, and if so, navigate to the login page
	return Backbone.Model.extend({
