+\nwanchorto{http://documentcloud.github.com/backbone/}{Backbone.js} is
+a popular Model-View-Controller (MVC) library that provides a
+framework by which models generate events and views reflect those
+events. The models represent data and ways in which that data can be
+chnaged. The nifty features of backbone are (1) its event-driven
+architecture, which separate a complex, working model of
+\textbf{objects} and their relationships, and the way those things and
+their relationships are presented to the viewer, and (2) its router,
+which allows developers to create bookmark-ready URLs for specialized
+views. Backbone also provides a Sync library which will RESTfully
+shuttle objects back and forth between the browser and the client.

+We will be creating a store for music albums. There will be: (1) The
+catalog of products, (2) A detail page for a specific product from the
+catalog, (3) A ``checkout page'' where users can add/change/delete
+items from their shopping cart, and (4) a shopping cart ``widget''
+that is visible on every page, and allows the user to see how many
+items are in the cart and how much money those items cost.
-\subsection{HTML}
+This is taken, more or less, straight from The JSON Store. We will be
+getting our data from a simplified JSON file that comes in the
+download; it contains six record albums that the store sells. (Unlike
+the JSON store, these albums do not exist; the covers were generated
+during a round of
+\nwanchorto{http://elfs.livejournal.com/756709.html}{The Album Cover
+ Game}, a meme one popular with graphic designers.)
+
+Under the covers, we have two essential objects: a \textbf{Product}
+that we're selling, and a shopping cart \textbf{Item} into which we
+put a reference to a Product and a count of the number of that product
+that we're selling. In the Backbone idiom, we will be callling the
+cart an \textbf{ItemCollection} that the user wants to buy, and the
+Products will be kept in a \textbf{ProductCollection}
+
+In backbone's parlance, Product and Item are \textbf{Models}, and Cart
+and Catalog are \textbf{Collections}. The idiom is that models are
+named for what they represent, and collections are model names
+suffixed with the word ``collection.'' The pages ``catalog,''
+``product detail,'' and ``checkout'' are \textbf{Routable Views},
+while the shopping cart widget is just a \textbf{View}. There's no
+programmatic difference internally between the two kinds of views;
+instead, the difference is in how they're accessed.
+
+\subsection{Models}
+
+The first version of this tutorial concentrated on the HTML. In this
+version, we're going to start logically, with the models. The first
+model is \textbf{Product}, that is, the thing we're selling in our
+store. We will create Products by inheriting from Backbone's
+\textbf{Model}.
+
+Backbone models use the methods [[get()]] and [[set()]] to access the
+attributes of the model. When you want to change a model's attribute,
+you must do so through those methods. Any other object that has even
+a fleeting reference to the model can then subscribe to the
+\textbf{change} event on that model, and whenever [[set()]] is called,
+those other objects can react in some way. This is one of the most
+important features of Backbone, and you'll see why shortly.
+
+Because a Backbone model maintains its attributes as a javascript
+object, it is schema-free. So the Product model is ridiculously
+simple:
+
+<>=
+ var Product = Backbone.Model.extend({})
+
+@
+
+And we said before, the products are kept in a catalog. Backbone's
+``list of models'' feature is called a \textbf{Collection}, and to
+stay in Backbone's idioms, rather than call it ``Catalog'', we'll call
+it a \textbf{ProductCollection}:
+
+<>=
+ var ProductCollection = Backbone.Collection.extend({
+ model: Product,
+
+ comparator: function(item) {
+ return item.get('title');
+ }
+ });
+
+@
+
+Collections have a reference to the Product constructor; if you call
+[[Collection.add()]] with a JSON object, it will use that
+constructor to create the associated Backbone model object.
+
+The other novel thing here is the comparator; Backbone uses it define
+the default ordering for the collection. If not defined, calling
+[[sort()]] on the collection raises an exception.
+
+Shopping carts have always seemed a bit strange to me, because each
+item isn't a one-to-one with a product, but a reference to the product
+and a quantity. For our (simple) purpose, I'm just going to have an
+item that you can add amounts to, that get stored as a 'quantity'.
+
+<>=
+ var Item = Backbone.Model.extend({
+ update: function(amount) {
+ this.set({'quantity': this.get('quantity') + amount});
+ }
+ });
+
+@
+
+The other feature is that, for the collection, I will want to find the
+CartItem not by its ID, but by the product it contains, and I want the
+Cart to be able to host any product, even it it has none of those, So
+I have added the method [[getOrCreateItemForProduct]]. The
+[[detect()]] and [[reduce()]] methods ares provided by Backbone's one
+major dependency, a wonderful utility library called
+\texttt{Underscore}. [[detect()]] returns the first object for which
+the anonymous function return [[true]]. The [[reduce()]] functions
+take an intitial value and a means of calculating a per-object value,
+and reduce all that to a final value for all objects in the
+collection.
+
+<>=
+ var ItemCollection = Backbone.Collection.extend({
+ model: Item,
+ getOrCreateItemForProduct: function(product) {
+ var i,
+ pid = product.get('id'),
+ o = this.detect(function(obj) {
+ return (obj.get('product').get('id') == pid);
+ });
+ if (o) {
+ return o;
+ }
+ i = new Item({'product': product, 'quantity': 0})
+ this.add(i, {silent: true})
+ return i;
+ },
+ getTotalCount: function() {
+ return this.reduce(function(memo, obj) {
+ return obj.get('quantity') + memo; }, 0);
+ }
+ getTotalCost: function() {
+ return this.reduce(function(memo, obj) {
+ return (obj.get('product').get('price') *
+ obj.get('quantity')) + memo; }, 0);
+
+ }
+ });
+
+@
+
+\subsection {Views}
+
+Now that we have the structure for our catalog and our shopping cart
+laid out, let's show you how those are organized visually. I'd like
+to say that it's possible to completely separate View and their
+descriptions of how to interact with the DOM with DOM development, but
+we must have some preliminary plans for dealing with the display.
+
+The plan is to have a one-page display for everything. We will have
+an area of the screen allocated for our major, routable views (the
+product list display, the product detail display, and the checkout
+display), and a small area of the screen allocated for our shopping
+cart. Let's put the shopping cart link in the upper-right-hand
+corner; everybody does.
+
+As an additional feature, we want the views to transition elegantly,
+using the jQuery [[fadeIn()]] and [[fadeOut()]] animations.
+
+Backbone Views are simple policy objects. They often have a root
+element, the contents of which they manipulate, a model or collection
+they represent within that root element, events that may occur within
+that root element that they monitor and consequently act on. Views
+are not rigid; it's just Javascript and the DOM, and you can hook
+external events as needed. (This can be useful, for example, when
+doing drag-and-drop with jQueryUI to highlight valid drop zones.)
+More importantly, it is sensitive to events \textit{within its model
+ or collection}, and can respond to changes automatically, without
+having to manually invoke the view.
+
+A Backbone view can be either an existing DOM element, or it can
+generate one automatically at (client-side) run time. In the previous
+version of the tutorial, I used existing DOM elements, but for this
+one, almost everything will be generated at run time.
+
+To achieve the animations and enforce consistency, we're going to
+engage in classic object-oriented programming. We're going to create
+a base class that contains knowledge about the main area into which
+all views are rendered, and that manages these transitions. With this
+technique, you can do lots of navigation-related tricks: you can
+highlight where the user is in breadcrumb-style navigation; you can
+change the class and highlight an entry on a nav bar; you can add and
+remove tabs from the top of the viewport as needed.
+
+<>=
+ var _BaseView = Backbone.View.extend({
+ parent: '#main',
+ className: 'viewport',
+
+@
+
+The above says that we're creating a class called \texttt{BaseView}
+and defining two fields. The first, 'parent', will be used by all
+child views to identify in which DOM object the view will be rendered.
+The second defines a common class we will use for the purpose of
+identifying these views to jQuery. Backbone automatically creates a
+new [[DIV]] object with the class 'viewport' when a view
+constructor is called. It will be our job to attach that [[DIV]]
+to the DOM.
+
+<>=
+ initialize: function() {
+ this.el = $(this.el); //$
+ this.el.hide();
+ this.parent.append(this.el);
+ return this.
+ },
+@
+
+The method above ensures that the element is rendered, but not
+visible, and contained within the [[DIV#main]]. Note also that
+the element is not a sacrosanct object; the Backbone.View is more a
+collection of standards than a mechanism of enforcement, and so
+defining it from a raw DOM object to a jQuery object will not break
+anything.
+
+Next, we will define the hide and show functions:
+
+<>=
+ hide: function() {
+ if (this.el.is(":visible") === false) {
+ return null;
+ }
+ promise = $.Deferred(function(dfd) { //$
+ this.el.fadeOut('fast', dfd.resolve)
+ }).promise();
+ this.trigger('hide', this);
+ return promise;
+ },
+
+ show: function() {
+ if (this.el.is(':visible')) {
+ return;
+ }
+ promise = $.Deferred(function(dfd) { //$
+ this.el.fadeIn('fast', dfd.resolve)
+ }).promise();
+
+ this.trigger('show', this);
+ return promise;
+ }
+@
+
+\textbf{Deferred} is a new feature of jQuery. It is a different
+mechanism for invoking callbacks by attaching attributes and behavior
+to the callback function. By using this, we can say thing like
+``\textit{When} everything is hidden (when every deferred returned
+from \textbf{hide} has been resolved), \textit{then} show the
+appropriate viewport.'' Deferreds are incredibly powerful, and this
+is a small taste of what can be done with them.
+

-This is taken, more or less, straight from The JSON Store. I've
-included one extra thing, aside from jQuery and Backbone, and that's
-the \nwanchorto{https://github.com/jquery/jquery-tmpl}{jQuery
- Templates kit}. There is also a simplified JSON file that comes in
-the download; it contains six record albums that the store sells.
-(Unlike the JSON store, these albums do not exist; the covers were
-generated during a round of

+It's not much to look at, but already you can see where that
+[[DIV#main]] goes, as well as where we are putting our templates.
+The [[DIV#main]] will host a number of viewports, only one of
+which will be visible at any given time.
+
+Our first view is going to be the product list view, named, well,
+guess. Or just look down a few lines.
+
+This gives us a chance to discuss one of the big confusions new
+Backbone users frequently have: \textit{What is \texttt{render()}
+ for?}. Render is not there to show or hide the view.
+\texttt{Render()} is there to \textit{change the view when the
+ underlying data changes}. It renders the data into a view. In our
+functionality, we use the parent class's \texttt{show()} and
+\texttt{hide()} methods to actually show the view.
+
+<>=
+ var ProductListView = _BaseView.extend({
+ id: 'productlistview',
+ indexTemplate: $("#store_index_template").template(), //$
+
+ render: function() {
+ self.el.html(_.template(this.template, {'products': this.model.toJSON()}))
+ return this;
+ }
+ });
+
+@
+
+That \texttt{\_.template()} method is provided by undescore.js, and is
+a fairly powerful templating method. It's not the fastest or the most
+feature-complete, but it is more than adequate for our purposes and it
+means we don't have to import another library. It vaguely resembles
+ERB from Rails, so if you are familiar with that, you should
+understand this fairly easily.
+
+And here is the HTML:
+
+<>=
+
+@
+%$
+
+One of the most complicated objects in our ecosystem is the product
+view. It actually does something! The prefix ought to be familiar,
+but note that we are again using [[#main]] as our target; we will be
+showing and hiding the various [[DIV]] objects in [[#main]] again and
+again.
+
+The only trickiness here is twofold: the (rather hideous) means by
+which one calls the method of a parnt class from a child class via
+Backbone's class heirarchy (this is most definitely \textbf{not}
+Javascript standard), and keeping track of the itemcollection object,
+so we can add and change items as needed.
+
+<>=
+ var ProductListView = _BaseView.extend({
+ id: 'productlistview',
+ indexTemplate: $("#store_item_template").template(), //$
+ initialize: function(options) {
+ this.constructor.__super__.initialize.apply(this, [options])
+ this.itemcollection = options.itemcollection;
+ return this;
+ },
+
+@
+
+We want to update the cart as needed. Remember the way Backbone is
+supposed to work: when we update the cart, it will send out a signal
+automatically, and subscribers (in this case, that little widget in
+the upper right hand corner we mentioned earlier) will show the
+changes.
+
+These are the events in which we're interested: keypresses and clicks
+on the update button and the quantity form. (Okay, ``UQ'' isn't the
+best for ``update quantity''. I admit that.) Note the peculiar
+syntax of ``EVENT SELECTOR'': ``methodByName'' for each event.
+
+Backbone tells us that the only events it can track by itself are
+those that jQuery's ``delegate'' understands. As of 1.5, that seems
+to be just about all of them.
+
+<>=
+ events: {
+ "keypress .uqf" : "updateOnEnter",
+ "click .uq" : "update",
+ },
+
+@
+
+And now we will deal with the update. This code ought to be fairly
+readable: the only specialness is that it's receiving an event, and
+we're ``silencing'' the call to [[cart.add()]], which means that the
+cart collection will not publish any events. There are only events
+when the item has more than zero, and that gets called on
+[[cart_item.update()]].
+
+In the original tutorial, this code had a lot of responsibility for
+managing the shopping cart, looking into it and seeing if it had an
+item for this product, and there was lots of accessing the model to
+get its id and so forth. All of that has been put into the shopping
+cart model, which is where it belongs: \textit{knowledge about items
+ and each item's relationship to its collection belongs in the
+ collection}.
+%'
+
+<>=
+ update: function(e) {
+ e.preventDefault();
+ var item = this.itemcollection.getOrCreateItemProduct(this.model);
+ item.update(parseInt($('.uqf').val()));
+ },
+
+ updateOnEnter: function(e) {
+ if (e.keyCode == 13) {
+ return this.update(e);
+ }
+ },

-\section{Models and Collections for the Store}
-
-Products are basically what we're selling. In Backbone, a product
-maps to a Backbone Model. Backbone's Model class provides a full
-suite of methods for setting and deleting attributes.
-
-One of things I've found useful is to expose the CID (an internal and
-locally unique ``client ID'' generated by Backbone) and use it to
-decorate DOM id's and classes. So, here, I override the Models's
-[[toJSON()]] and add the CID to the representation. In production,
-I've typically created a parent class for all of my classes, overriden
-[[toJSON()]], and extended that instead.
-
-<>=
- var Product = Backbone.Model.extend({
- toJSON: function() {
- return _.extend(_.clone(this.attributes), {cid: this.cid})
- }
- });
-
-@
-
-A store has a lot of products, so we use a Backbone Collection to keep
-track of them. A Collection always has a Model object associated with
-it; if you attempt to add an object to the Collection that is not an
-instance of [[Backbone.Model]], the Collection will attempt to coerce
-that object into it [[model]] type.
-
-Both Models and Collections have a [[toJSON()]] method. The Model
-creates a JSON representation of its attributes, and the collection
-creates a JSON representation of an array, calling [[Model.toJSON()]]
-for each model in contains.
-
-
-The other novel thing here is the comparator; Backbone uses it define
-the default ordering for the collection. If not defined, calling
-[[sort()]] on the collection raises an exception.
-
-<>=
- var ProductCollection = Backbone.Collection.extend({
- model: Product,
-
- comparator: function(item) {
- return item.get('title');
- }
- });
-@
-
-Shopping carts are a bit strange. The typical cart has items: each
-item represents one product and the quantity the user wants to buy.
-So a cart may have two items, but the user may be buying five things:
-one of the first item, and four of the second, and so forth.
-
-For our (simple) purpose, I'm just going to have an item that you can
-add amounts to, that get stored as a 'quantity'.
-
-<>=
- var CartItem = Backbone.Model.extend({
- update: function(amount) {
- this.set({'quantity': this.get('quantity') + amount});
- }
- });
-
-@
-
-The other feature is that, for the collection, I will want to find the
-CartItem not by its ID, but by the ID of the product it contains. So
-I have added the method [[getByProductId]].
-
-<>=
- var Cart = Backbone.Collection.extend({
