    <p>Your service shouldn't interact with the DOM directly as you're trying to do. If I were designing such a system I would:</p> <ol> <li>Have a service which simply takes in messages and either puts them in an array (if you want to support a whole list of messages) or simply remembers the last message (if you only want to support a single message)</li> <li>Have a controller which gets the message service injected to it and binds the message(s) from the service into its scope</li> <li>Then have a bit of HTML (or a custom directive) that iterates the messages using the above controller and displays them</li> </ol> <p>Here's what I mean (plunk here: <a href="http://plnkr.co/Eps1Gy" rel="nofollow">http://plnkr.co/Eps1Gy</a>)</p> <p>index.html:</p> <pre><code>&lt;!doctype html&gt; &lt;html&gt; &lt;head&gt; &lt;script src="bower_components/angular/angular.js"&gt;&lt;/script&gt; &lt;script src="scripts/app.js"&gt;&lt;/script&gt; &lt;script src="scripts/controllers/messages.js"&gt;&lt;/script&gt; &lt;script src="scripts/controllers/click.js"&gt;&lt;/script&gt; &lt;script src="scripts/services/messageService.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body ng-app="messagesApp"&gt; &lt;h1&gt;Messages&lt;/h1&gt; &lt;div ng-controller="MessagesCtrl"&gt; &lt;ul ng-repeat="message in messages"&gt; &lt;li&gt;{{message}}&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;a ng-href="#" ng-controller="ClickCtrl" ng-click="addMessage()" &gt;Add a new message!&lt;/a&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>messageService.js:</p> <pre><code>function MessageService() { this.messages = []; this.add = function(msg) { this.messages.push(msg); } } angular.module('messagesApp') .service('messageService', MessageService); </code></pre> <p>messages.js:</p> <pre><code>angular.module('messagesApp') .controller('MessagesCtrl', function ($scope, messageService) { $scope.messages = messageService.messages; }); </code></pre> <p>click.js:</p> <pre><code>angular.module('messagesApp') .controller('ClickCtrl', function ($scope, messageService) { var count = 0; $scope.addMessage = function() { messageService.add('Test message ' + count++); } }); </code></pre> <p>app.js:</p> <pre><code>angular.module('messagesApp', []) .config(function ($routeProvider) { $routeProvider .otherwise({ redirectTo: '/' }); }); </code></pre> <p>Like I said, you can replace the HTML for handling the messages with a custom directive if you want some complex interaction, but the important thing is that you don't try to muck with the view from your service. The service should interact only with a well-defined model.</p>

    1. COCan you create a Plunker? I tried, and I can't get this to work. I'm also not clear on how any of this would work without an $apply() somewhere in there. In click.js, you are pushing onto the MessageService array, but how will the binding in MessagesCtrl be informed of this?

    3. COThe reason adding to the array is instantly reflected in the UI is THE magic of angular.js. It automatically watches things bound into your scope and anything that depends on them is updated instantly. The example could also be better encapsulated by the messageService exposing a getMesages() rather than exposing the array of messages directly.

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).
