<p>I'm trying to fetch some data and display it with Backbone, but having no luck - I am not getting any errors, just no rendering (I built this really simple app using the todos example as a guide)</p> <p>index.html:</p> <pre><code><!doctype html> <html> <head> <title>Hello Backbone</title> </head> <body> <div id="sps-container"> <div id="main"> <ul id="service-providers"></ul> </div> </div> </body> <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.5.2/underscore-min.js"></script> <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.0/backbone-min.js"></script> <script type="text/javascript" src="/app.js"></script>  <script type="text/template" id="sp-template"> <div class="view"> <label><%- name %></label> </div> </script> </html> </code></pre> <p>app.js</p> <pre><code>$(function(){ var ServiceProvider = Backbone.Model.extend({ defaults : function() { return { id : "", version : 1, name : "" }; } }); var ServiceProviderList = Backbone.Collection.extend({ url: '/web-admin/faces/Backbone/data.json', model : ServiceProvider }); var myCollection = new ServiceProviderList(); var ServiceProviderView = Backbone.View.extend({ el : $("#service-providers"), tagName : "li", initialize : function() { _.bindAll(this, 'render'); this.template = _.template($('#sp-template').html()); this.render(); }, render : function() { this.$el.html(this.template(this.model.toJSON())); return this; } }); myCollection.fetch(function(c) { var v = new ServiceProviderView(c); main.html(v.render().el); }); var SPView = new ServiceProviderView(); }); </code></pre> <p>data.json</p> <pre><code>[ { "id": "03c88b31-6719-4662-9ad8-64f247de13f0", "version": 1, "name": "Dino Tel" }, { "id": "936690b4-6a4a-436d-abed-8ca316fbae22", "version": 1, "name": "Krusty Tel" } ] </code></pre> <p>I think it's not loading any data - there are no other errors though, and the json file is available. Am I missing something?</p>

Guidance

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.
