    <blockquote> <p>So now to the big question: is there a better way to access the router or a controller from outside Ember? Preferably send an event to either with a context.</p> </blockquote> <p>Yes. This sounds like a good fit for the ember instrumentation module. Have an appropriate controller subscribe to SignalR events, then trigger them whenever your app handles real-time notification. </p> <p>First, add a method to ApplicationController for processing updates. If not defined here the event would bubble to the router.</p> <pre><code>App.ApplicationController = Ember.Controller.extend({ count: 0, name: 'default', signalrNotificationOccured: function(context) { this.incrementProperty('count'); this.set('name', context.name); } }); </code></pre> <p>Next, setup your ApplicationController by subscribing to the <code>signalr.notificationOccured</code> event. Use the before callback to log the event and send it's payload to the controller.</p> <pre><code>App.ApplicationRoute = Ember.Route.extend({ setupController: function (controller, model) { Ember.Instrumentation.subscribe("signalr.notificationOccured", { before: function(name, timestamp, payload) { console.log('Recieved ', name, ' at ' + timestamp + ' with payload: ', payload); controller.send('signalrNotificationOccured', payload); }, after: function() {} }); } }); </code></pre> <p>Then from your SignalR Application, use <code>Ember.Instrumentation.instrument</code> to send payload to your ApplicationController as follows:</p> <pre><code>notificator.update = function (context) { Ember.Instrumentation.instrument("signalr.notificationOccured", context); }); </code></pre> <p>I posted a working copy with simulated SignalR notifications here: <a href="http://jsbin.com/iyexuf/1/edit" rel="noreferrer">http://jsbin.com/iyexuf/1/edit</a></p> <p>Docs on the instrumentation module can be found <a href="http://emberjs.com/api/classes/Ember.Instrumentation.html" rel="noreferrer">here</a>, also check out the <a href="https://github.com/emberjs/ember.js/blob/master/packages/ember-metal/tests/instrumentation_test.js" rel="noreferrer">specs</a> for more examples.</p>

    1. COinstrument as a name to send a signal is quite confusing in my opinion. What does 'Instrument a block of code by using `Ember.instrument` mean exactly: send signal with a specified name and payload and call the callback at the end ? Btw good catch.

    2. COSweet, this was perfect! This design is excact what I was looking for. Works like a charm too.

    3. COMike, this might be just what I'm looking for, but can this be used for general purpose events or only for rendering? Does it only bubble upwards or can any object listen for an event triggered by any other object? Ideally I'd love to be able to duplicate jQuery's $.trigger() which lets you set up bespoke events anywhere, and trigger them FROM anywhere.

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.
