<p>I am new to Ember and I am trying to use an Ember View to observe a property change in my controller. I am able to log the view, but the handler doesn't fire when the property changes.</p> <p>I am basically trying to learn the Ember way to remove an item from the view when the user clicks to delete a record. I haven't found really a good guide on this. Any advice is appreciated.</p> <p>Please let me know if I'm leaving anything out. Thanks in advance!</p> <p>(This is an inherited codebase; we aren't ready to upgrade Ember yet.)</p> <blockquote> <p>Ember v1.0.0-rc.3</p> </blockquote> <h3>Route</h3> <pre><code>this.resource('posts'); </code></pre> <pre class="lang-js prettyprint-override"><code>App.PostsRoute = App.AuthenticatedRoute.extend({ // extension of Em.Route model: function() { return App.Post.list(); // returns a list of posts }, events: { // renders a modal in the post context showDeleteModal: function(model) { this.render('modals/_confirmation', { into: 'posts', outlet: 'modal', controller: 'post' }); this.controllerFor('post').set('model', model); } } }); </code></pre> <h3>Controller</h3> <pre class="lang-js prettyprint-override"><code>App.PostsController = Em.ObjectController.extend(App.PagedTable, Ember.Evented, { // ... }); App.PostController = Em.ObjectController.extend({ foo: false, del: function() { this.set('foo', true); } }); </code></pre> <h3>View</h3> <pre class="lang-js prettyprint-override"><code>App.PostsView = Em.View.extend(); App.PostView = Em.View.extend({ didInsertElement: function() { console.log('Inserted!'); }, test: function() { console.log('Observed!'); }.observes('controller.foo') }); </code></pre> <h3>Template</h3> <pre><code>{{#each data in currentDataBlocks itemController="post" itemViewClass="App.PostView"}} <tr> <td>Stuff</td> <td>Stuff</td> <td>Stuff</td> <td>Stuff</td> <td><button class="icon-trash" {{action showDeleteModal data}}></button></td> </tr> {{/each}}  {{outlet modal}} </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.
