This allow Handlebars to look up Backbone Model's attributes: {{ user.address.street }} If user is a Backbone Model this will become user.get("address").street And if user.get("adress") is also a Backbone Model this will be produced: user.get("address").get("street")

Handlebars- Backbone.js

Handlebars.JavaScriptCompiler.prototype.nameLookup = function(parent, name, type) {
	var result = '(' + parent + ' instanceof Backbone.Model ? ' + parent + '.get("' + name + '") : ' + parent;
	if (/^[0-9]+$/.test(name)) {
		return result + "[" + name + "])";
	} else if (Handlebars.JavaScriptCompiler.isValidJavaScriptVariableName(name)) {
		return result + "." + name + ')';
	} else {
		return result + "['" + name + "'])";
	}
};

Tested with Handlebars 1.0.rc.1

WARNING: Don't use it if Backbone.Model isn't global, it will broke all the templates.

Handlebars exposes this function in order to allow us to overwrite it.

I love this. Thank you!

Great ! Thank you !
