    <p>I have a collection of foos, and each foo has its own collection of bars. I want to be able to display a selected foo using routes, but then the foo's bars are listed as part of the display.</p> <p>All that is straight forward except that each bar may contain an attribute that means I want to apply different styles to it. So, I am using a <em>render</em> handlebars helper inside an <em>each</em> , like so -</p> <pre><code>&lt;script type="text/x-handlebars" id="foo"&gt; &lt;div&gt;{{name}}&lt;/div&gt; &lt;div&gt; &lt;table&gt; {{#each bar in bars}} {{render bar bar}} {{/each}} &lt;/table&gt; &lt;/div&gt; &lt;/script&gt; </code></pre> <p>and the bar template looks like this -</p> <pre><code>&lt;script type="text/x-handlebars" data-template-name="bar"&gt; &lt;tr&gt;&lt;td&gt; &lt;div {{bind-attr class="bar.bold:bold"}}&gt;{{bar.name}}&lt;/div&gt; &lt;/td&gt;&lt;/tr&gt; &lt;/script&gt; </code></pre> <p>The thing is that I can't figure out how to define the controller. The above just works if the model contains bars with a bold property but what if that's not the case and I need to calculate the property?</p> <p>I tried variations on this -</p> <pre><code>App.BarController = Ember.ObjectController.extend({ isBold: function(){ return this.get('bold'); }.property('isBold'),}); </code></pre> <p>(modifying the bind-attr helper accordingly), and I put a breakpoint on the return. It is never hit.</p> <p>I have a jsfiddle here (<a href="http://jsfiddle.net/martinp999/ZbjH9/7/" rel="nofollow">http://jsfiddle.net/martinp999/ZbjH9/7/</a>). Any advice would be appreciated. Thanks</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.
