    <p>I am a newbie to javascript/angularjs. I want to show a bootstrap popover when mouseover is done on some elements. </p> <p>I created a directive for that</p> <pre><code>(function(angular, app) { app.directive('popOver',["$window","$http",function($window,$http){ return function(scope,elem,attrs){ elem.on('mouseover',function(){ console.log('mouseover'); var data = scope.$apply(attrs.popOver); console.log('in directive again'); console.log(data); }); }; }]); })(angular, app); </code></pre> <p>the value of the directive is a function </p> <p><code>&lt;span class="asdf" pop-over="getVCard(id)"&gt;name&lt;/span&gt;</code></p> <p>the function vcard(id) is defined in my angularjs controller. It checks if the data is already there in localstorage and if present, returns the data. otherwise it does a $http get request and stores the data in localstorage. </p> <pre><code>$scope.getVCard = function(id){ var vcardKey = vcardKeyPrefix+id; var vCardFromLS = localStorageService.get(vCardKey); if(vCardFromLS){ return localStorageService.get(vCardKey); } $http.get(app.common.vcardUrl(id)). success(function(data){ localStorageService.set(vCardKey,data); }). error(function(error){ F1.common.error(data,function(){}); }); return localStorageService.get(vCardKey); }; </code></pre> <p>Since $http returns promise, i am getting a value of undefined in my directive. How can i make sure that the function <code>getVCard</code> returns synchronously?</p> <p>I read a number of results after googling. But the suggested idea is to use callbacks. But i am not sure how callbacks will make this synchronous. Any help is appreciated.</p> <p><strong>UPDATE 1</strong> (in response to Foo L's comment) i was planning to use the same directive in multiple places. popovers for vcards and product information and so on. The only thing that will differ is the argument to the pop-over directive. That way the directive will bother about just displaying the popup. Where to get the data will be in a separate function that is passed to the directive</p>

    1. COWhat about just passing in the function & id separately into the directive? You can call the function with the id as parameter inside & set up a `scope.$watch` that will trigger when it returns successfully.

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).
