<p>If you prefer to see the question in working code, start here: <a href="http://jsbin.com/ayigub/2/edit" rel="nofollow noreferrer">http://jsbin.com/ayigub/2/edit</a></p> <p>Consider this almost equivalent ways to write a simple direcive:</p> <pre><code>app.directive("drinkShortcut", function() { return { scope: { flavor: '@'}, template: '<div>{{flavor}}</div>' }; }); app.directive("drinkLonghand", function() { return { scope: {}, template: '<div>{{flavor}}</div>', link: function(scope, element, attrs) { scope.flavor = attrs.flavor; } }; }); </code></pre> <p>When used by themselves, the two directives work and behave identically:</p> <pre><code>  <div drink-shortcut flavor="blueberry"></div> <hr/>  <div drink-longhand flavor="strawberry"></div> <hr/> </code></pre> <p>However, when used within an ng-repeat, only the shortcut version works:</p> <pre><code>  <div ng-repeat="flav in ['cherry', 'grape']"> <div drink-shortcut flavor="{{flav}}"></div> </div> <hr/>  <div ng-repeat="flav in ['cherry', 'grape']"> <div drink-longhand flavor="{{flav}}"></div> </div> </code></pre> <p>My questions are:</p> <ol> <li>Why does the longhand version not work inside an ng-repeat?</li> <li>How could you make the longhand version work inside an ng-repeat?</li> </ol>

Guidance

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.
