+\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'll fill it with templated data later.
+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:
+
+<<product models>>=
+    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}:
+
+<<product models>>=
+    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'.
+
+<<shopping cart models>>=
+    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.
+
+<<shopping cart models>>=    
+    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.
+
+<<base view>>=
+    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.
+
+<<base view>>=
+        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:
+
+<<base view>>=
+        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 gives us a chance to discuss one of the big confusions new

+  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.

+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.
+
+<<product detail view>>=
+    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.  
+
+<<product view>>=
+        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}.

+<<product view>>=
+        update: function(e) {
+            e.preventDefault();
+            var item = this.itemcollection.getOrCreateItemProduct(this.model);
+            item.update(parseInt($('.uqf').val()));
+        },

-\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.
-
-<<product models>>=
-    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.
-
-<<product models>>=
-    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'.
-
-<<shopping cart models>>=
-    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]].
-
-<<shopping cart models>>=    
-    var Cart = Backbone.Collection.extend({
-        model: CartItem,
-        getByProductId: function(pid) {

-
-    Revision history
-    ----------------
-    v1.0.1  - 4 Dec 2008
-    - Extended $.getValidJSON(params) API so you can define 
-      { schema : { send : xxx, receive : zzz } } so you can 
-      optionally validate data on the way out and on the way in.
-    - Added tests to ensure that the schema key defined does really 
-      exist as a typeof "object" in validJSONSchemas.
-
-    v1.0.0  - 3 Dec 2008
-    - initial release
-
-
-    Support
-    -------
-    For support, suggestions or general discussion please visit the #SOAPjr irc
-    channel on freenode.net or visit http://SOAPjr.org 
-
-
-    Implementation overview
-    -----------------------
-    NOTE:   This work contributes to the SOAPjr Data Model Definition project
-            that is designed to encourage the adoption and use of common JSON
-            data models with common SOAPjr APIs.
-
-            See http://soapjr.org/specs.html#dmd for more information
-
-    1.  Include the jquery.js, jsonschema-b2.js and jquery.ValidJSON.js src files
-        into your html page - optionally include the jquery.SOAPjr.js plugin too
-
-    2.  Add a call to the $(document).ready(function() { ... }) block to load
-        the relevant JSON Schema definition files you require
-
-        e.g.
-                - http://soapjr.org/schemas/SOAPjr_request
-                - see http://json-schema.org/shared.html for common formats
-
-    3.  Get the JSON files/objects you require using the $.getValidJSON() API
-
-    4.  Check the "result.valid" boolean and "result.errors" array for any
-        validation errors and if all is good then use "json" like normal.
-
-    5.  Sleep well knowing your data is cleanly validated and conforms to your
-        chosen schema.
-
-
-    Code usage examples
-    -------------------
-    1. Include src files
-
-        <script type="text/javascript" src="jquery-1.2.6.js"></script>
-        <script type="text/javascript" src="jsonschema-b2.js"></script>
-        <script type="text/javascript" src="jquery.ValidJSON.js"></script>
-
-
-    2. Add calls to load schema files
-
-        <script type="text/javascript">
-        $(document).ready(function() {
-            //load them from a URL
-            $.getValidJSONSchemas({
-                //id          //url
-                "card"      : "http://json-schema.org/card",
-                "calendar"  : "http://json-schema.org/calendar"
-            });
-
-            //import them from a local var
-            $.setValidJSONSchemas({
-                //id          //pre-populated vars (possibly included in .js files)
-                "geo"       : geoschema_var,
-                "address"   : addressschema_var
-            });
-        });
-        </script> 
-
-        NOTE: cross-domain xhr restrictions apply - look at JSONP for cross domain requests
-
-
-    3. Get the JSON files/objects
-
-        <script type="text/javascript">
-        function do_your_stuff() {
-            //collect data from a form or setup a stub
-            var params = { ... };
-
-            //get your data and validate it in one call
-            var xhr = $.getValidJSON({
-                "url"           : url,                                              //required
-                "data"          : params,                                           //optional
-                "callback"      : "my_callback",                                    //required (see point 4 below)
-                "schema"        : { "send":"schema_id1", "receive":"schema_id2" }   //optional - can be defined within the response JSON object using $schema
-            });
-        }
-        </script>
-
-
-    4. Check the validation results/errors
-
-        <script type="text/javascript">
-        //setup your callback to handle the json data and any validation errors
-        function my_callback(result, json) {
-            if (result.valid) {
-                //json contains a valid XXX data object
-            } else {
-                for (var e in result.errors) {
-                    //e.property tells you which value is invalid
-                    //e.message is a human readable error message
-                }
-            }
-        }
-        </script>
-
-
-    5. Relax
-        
-        This plugin will let you do field level schema based validation.
-        You can also connect this to your form validation for standardised form data.
-        And you can use it in combination with the SOAPjr plugin to make sure
-        your apps handle metadata and complex/multiple errors seamlessly.
-
-        Isn't technology great! 8)
