    <p>We're doing a lot of work around dynamic directives in our Angular project, and one thing that came up as a nice-to-have was a way to have a generic directive that can list many different types of similar objects (e.g., messages, users, comments, etc.), by delegating to specific directives based on the objects' types.</p> <p>We call this directive, <code>object-list</code> and it will hopefully delegate to a number of different directives, if we can get it working properly.</p> <p>The main issue we need to tackle is whether or not a directive that this <code>object-list</code> directive has been provided exists in our system. The way we've been checking this is by issuing a <code>$compile</code> against the target directive, linking it to a scope, and checking its HTML contents (e.g., <code>var tmpElement = $compile('&lt;div my-message'&gt;&lt;/div&gt;')(scope);</code>). This seems to work when the template for the target directive is referenced by the <code>template</code> option, but when we instead try to point to a <code>templateUrl</code>, the HTML contents are empty.</p> <p>Here's a Plunker, with the <code>templateUrl</code> approach in place (not working). You can comment it out and uncomment the <code>template</code> line to see the alert show up.</p> <p><a href="http://plnkr.co/edit/wD4ZspbGSo68v4eRViTp">http://plnkr.co/edit/wD4ZspbGSo68v4eRViTp</a></p> <p>Is there another way to check the existence of a directive? I'll admit, this does seem a bit of a hack.</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.
