<p>Well I'll have to answer my own question on this one. As @peter-wagenet and @bradley-priest suggested, I did need to make use of the ability to send a context using the action helper.</p> <p>This used in conjunction with <code>{{#each item in list}}</code> I can set the context to the specific object being viewed.</p> <p>I also had to create Ember.Object(s) for the availableIn array of objects so that I could use the .set method.</p> <p>So without further ado, here's my working solution. If you have a better solution, I'd be more then happy to see it.</p> <p>Template</p> <pre><code><script type="text/x-handlebars" id="application"> <h1>If you're gonna survive out here, you've got to know where your towel is.</h1> {{outlet}} </script> <script type="text/x-handlebars" id="towel"> <h2>The availableIn:</h2> {{outlet}} </script> <script type="text/x-handlebars" id="towels"> {{#each item in availableIn}} <div> {{! The default click action will find the controller and look for doStuff and send it the event with the context set to item }} <a {{action doStuff item target="controller"}}>{{item.color}}</a> </div> {{/each}} </script> </code></pre> <p>Javascript</p> <pre><code>window.App = Ember.Application.create({ ready: function() { this.initialize(); } }); window.App.Router = Ember.Router.extend({ root: Ember.Route.extend({ index: Ember.Route.extend({ route: '/', connectOutlets: function(router) { var controller = router.get('applicationController'); controller.connectOutlet('towel'); controller = router.get('towelController'); controller.connectOutlet('towels'); } }) }) }); window.App.ApplicationView = Ember.View.extend({ templateName: 'application' }); window.App.ApplicationController = Ember.Controller.extend(); window.App.TowelController = Ember.ObjectController.extend(); window.App.TowelView = Ember.View.extend({ templateName: 'towel' }); // Towel Object model window.App.Towel = Ember.Object.extend({ name: null, availableIn: [], wetness: 0, isEditing: false }); // Style Object model window.App.Style = Ember.Object.extend({ color: null, size: null }); // Create some style instances var style1 = window.App.Style.create({ color: "red", size: "small" }); var style2 = window.App.Style.create({ color: "blue", size: "medium" }); // Create a towel instance var drt = window.App.Towel.create({ name: "Dry Towel", availableIn: [style1, style2], wetness: 0, isEditing: true }); // The Towels Controller window.App.TowelsController = Ember.ObjectController.extend({ // Set the content to our dummy data content: drt, // Define the action doStuff doStuff: function(event) { // Grab the context which is the object being cliked and change it's color property to 'purple' event.context.set('color', 'purple'); } }); // The Towels View window.App.TowelsView = Ember.View.extend({ templateName: 'towels' }); </code></pre> <p>Working fiddle: <a href="http://jsfiddle.net/EasyCo/cE2xP/" rel="nofollow">http://jsfiddle.net/EasyCo/cE2xP/</a></p>

1. COThis answer help me. My requirement was to invoke a method of the item in a loop(target="item"). Here goes the example. <script type="text/x-handlebars" id="towels"> {{#each item in availableIn}} <div> {{! The default click action will find the controller and look for doStuff and send it the event with the context set to item }} <a {{action doStuff item target="item"}}>{{item.color}}</a> </div> {{/each}} </script>

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.
