Body
<p>That's not possible that way. The best you can do is bind the directive scope to a function of its parent scope that returns an instance of your service:</p> <pre><code>app.directive('changeIt', function(){ return { restrict: 'CA', scope: { getDataFn : '&' }, link: function (scope) { scope.name = getDataFn().name; } } }); </code></pre> <p>and then in your view:</p> <pre><code><div class='change-it' get-data-fn='getMyData()'></div> <div class='change-it' get-data-fn='getYourData()'></div> </code></pre> <p>Finally, you need to add <code>getMyData()</code> and <code>getYourData()</code> to the parent scope:</p> <pre><code>app.controller('Ctrl', function($scope, myData, yourData) { $scope.getMyData = function() { return myData; }; $scope.getYourData = function() { return yourData; }; }); </code></pre> <p>Plunker script <a href="http://plnkr.co/edit/IdHeIiTn2TiDuovlIG9L?p=preview">here</a>.</p> <p>I can think of another approach, though: you could create an abstract factory and inject it into the directive, and then pass a parameter to the directive so it could tell the abstract factory to create the correct service. Something like this:</p> <pre><code>app.service('dataFactory', function(myData, yourData) { this.create = function(type) { if (type === 'myData') return myData; else if (type === 'yourData') return yourData; }; }); app.directive('changeIt', function(dataFactory){ return { restrict: 'CA', scope: true , link: function (scope, element, attrs) { scope.name = dataFactory.create(attrs.type).name; } } }); </code></pre> <p>And now you need to pass the type to the directive:</p> <pre><code><div class='change-it' type="myData"></div> <div class='change-it' type="yourData"></div> </code></pre> <p>Plunker <a href="http://plnkr.co/edit/q6Bf9AKLF8OrCEPdtY3Y?p=preview">here</a>.</p>

2. COI think you're able to define a simple controller that performs the datacall and pass it to the directive using ng-controller="YourCtrl"

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.
