    <p>Consider an application where one can trigger a database search by giving input to a textfield, then pressing enter. The search result should be shown immediately after.</p> <p>To accomplish this, i created an input element and gave it a directive attribute:</p> <pre><code>&lt;input search-shipment type="text"&gt; // Directive Shipment.directive('searchShipment',function(){ return{ restrict: 'A', link: function(scope,element){ element.bind('keydown',function(e){ if (e.which === 13){ scope.shipment.fetchShipment(); } }) } } }); </code></pre> <p>The function that was triggered:</p> <pre><code>Shipment.prototype.fetchShipment = function(){ $http.post('../sys/core/fetchShipment.php',{ // some data to POST }).success(function(data){ console.log(data); }); console.log(finished); }; </code></pre> <p>This caused some weird behaviour. The function was triggered, and "finished" was logged to the console. However, <code>success()</code> was apparently triggered to late, <code>data</code> was not logged until i made another input which has to be something different than <kbd>return</kbd></p> <p>Now i have figured out that i can avoid this behaviour by using a form as a wrapper for my input element, then using ng-submit to trigger my function. </p> <p>However, i wonder about some things:</p> <ul> <li>Why has my first, directive based solution not worked properly?</li> <li>How can i accomplish my goal without using a form?</li> <li>Even with the working form solution, the second <code>console.log()</code> is triggered <em>before</em> the logging of the data. Why is this?</li> </ul>

    1. COAs an answer to your third point: `console.log(data)` is within the callback function, which is only triggered after the response to the HTTP request is received. Since `console.log(finished)` is outside the callback, it'll be executed immediately after the HTTP request is made.

    2. COin addition to @godfrzero - $http has `always()` method (since 1.1.5 version) where you can put your `console.log(finished)`.

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).
