    <p>I'm writing a little threaded discussion board in angular. I want to use hallo.js for my inline editor (or something similar, the problem doesn't actually depend on hallo).</p> <p>Here's the relevant snippet from the template</p> <pre><code>&lt;div ng-show="post.editing" ng-bind-html="post.body" edit-hallo class="col-xs-8"&gt;&lt;/div&gt; &lt;div ng-show="!post.editing" ng-bind-html="post.body" class="col-xs-8"&gt;&lt;/div&gt; </code></pre> <p>Here's my directive:</p> <pre><code>Appl.directive('editHallo', function () { return { restrict: 'AC', scope: true, link: function(scope, element, attr) { element .hallo({ plugins: { 'halloformat': {"bold": true, "italic": true, "strikethrough": true, "underline": true}, 'halloheadings': [1,2,3], 'hallojustify' : {}, } }); element.bind('hallomodified', function(event, data) { scope.post.body = data.content; }); } }; }); </code></pre> <p>This all works just fine, but the hack is right there at the end - when there's a hallomodified event, I manually say, <code>scope.post.body = data.content</code> which not only feels like a hack, it means this only works when there's a post.body item that I'm editing, and therefore doesn't work well if I want to repurpose this for the profile editor or whatever.</p> <p>So my question is: how should I refactor this so that the relevant two-way binding works? I tried a few things that seemed obvious, such as putting a <code>app-model="post.body"</code> in the div, and then doing an isolate scope with =, but that wasn't getting me anywhere. Ideally, I'd pass in the appropriate model using an ng-model directive, but that seems to have changed sometime between when all the directive examples I found online were created and angular 1.2.0.</p>

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.
