    <p>I'm beginning with backbone.js</p> <p>Going through some tutorials, like the one shown below. I got the feeling, it is really more about how to organize your objects and how to instruct them to interact. And I can do them without backbone.js So backbone.js looks more like a set of rules, philosophies to me, then an actual plug-in for the most part. Is that what it is?</p> <pre><code>(function($){ var Item = Backbone.Model.extend({ defaults: { part1: 'hello', part2: 'world' } }); var List = Backbone.Collection.extend({ model: Item }); var ListView = Backbone.View.extend({ el: $('body'), events: { 'click button#add': 'addItem' }, initialize: function(){ _.bindAll(this, 'render', 'addItem', 'appendItem'); // remember: every function that uses 'this' as the current object should be in here this.collection = new List(); this.collection.bind('add', this.appendItem); // collection event binder this.counter = 0; this.render(); }, render: function(){ $(this.el).append("&lt;button id='add'&gt;Add list item&lt;/button&gt;"); $(this.el).append("&lt;ul&gt;&lt;/ul&gt;"); _(this.collection.models).each(function(item){ // in case collection is not empty appendItem(item); }, this); }, // `addItem()` now deals solely with models/collections. View updates are delegated to the `add` event listener `appendItem()` below. addItem: function(){ this.counter++; var item = new Item(); item.set({ part2: item.get('part2') + this.counter // modify item defaults }); this.collection.add(item); // add item to collection; view is updated via event 'add' }, // `appendItem()` is triggered by the collection event `add`, and handles the visual update. appendItem: function(item){ $('ul', this.el).append("&lt;li&gt;"+item.get('part1')+" "+item.get('part2')+"&lt;/li&gt;"); } }); var listView = new ListView(); })(jQuery); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
