    <p>I have a problem instanciating controller with Angular. I have a main controller <strong>AlkeTypeDefListController</strong> from which I want to dynamically create/remove controllers of type <strong>AlkeTypeDefController</strong>, so I have done that : </p> <p>Code of <strong>AlkeTypeDefListController</strong>:</p> <pre><code>// Create main controller Alke.controller('AlkeTypeDefListController', ['$scope', '$controller', function($scope, $controller) { var primitives = [ ]; // Add some properties to the scope angular.extend($scope, { typedefs : primitives, addTypeDef : function() { var controller = $controller("AlkeTypeDefController", {$scope:$scope.$new()}); $scope.typedefs.push(controller); } }); }]); </code></pre> <p>Code of <strong>AlkeTypeDefController</strong>:</p> <pre><code>// Create main controller Alke.controller('AlkeTypeDefController', ['$scope', '$controller', function($scope, $controller) { // Add some properties to the scope angular.extend($scope, { name : "New Type", fields : [], addField : function() { } }); }]); </code></pre> <p>The html code is this one:</p> <pre><code>&lt;div id="typedefs-editor" ng:controller="AlkeTypeDefListController"&gt; &lt;button ng:click="addTypeDef()"&gt;Add&lt;/button&gt; &lt;button&gt;Remove&lt;/button&gt; &lt;div id="typedef-list"&gt; &lt;ul class="list"&gt; &lt;li ng:repeat="typedef in typedefs"&gt;&lt;a href="#"&gt;{{typedef.name}}&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>The problem does not really come from the instantiation (which works fine), but from the initialization. In fact, when the new "li" appears when I push the "Add" button, the text "New type" (initialized in the controller) does not appear.</p> <p>I think it is about the scope or something like that, but I can't really find how to fix this.</p> <p>I wanted to know if this method seems correct, and also how could I fix the problem I have.</p> <p>Thanks</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.
