    <p>I've got a custom defined directive in angularjs. Basically what I want to happen is the user will pick a value from a select box and that will append a value to an array. This causes my custom directive to be invoked and render a new element on the screen. I want the text field that the directive generates to bind to the controller's attribute.</p> <p>Html</p> <pre class="lang-html prettyprint-override"><code>&lt;device-list ng-repeat="device in devices" key="device.key" display-name="device.display_name" bind-prefix="descriptions"&gt;&lt;/device-list&gt; </code></pre> <p>Directive</p> <pre class="lang-js prettyprint-override"><code>angular.module('device_list_tag', []). directive('deviceList', function() { return { restrict: 'E', require: '?ngModel', scope: { devices: '=', key: '=', displayName: '=', bindPrefix: '@' }, link: function(scope, element, attrs) { var deviceListElement = $(element) var containerDiv = $('&lt;div&gt;') .addClass('row') var labelTag = $('&lt;label&gt;').text(scope.displayName) .addClass('span1') var bindField = attrs.bindPrefix+'.'+scope.key var textField = $('&lt;input&gt;') .addClass('span3') .attr('ng-model', bindField) containerDiv.append(labelTag) containerDiv.append(textField) deviceListElement.append(containerDiv) } } }) </code></pre> <p>Controller</p> <pre class="lang-js prettyprint-override"><code>function DevicesCtrl($scope) { descriptions = {} } </code></pre> <p>It appears as though as ng-model is local to the directive's scope, how do I make it apply to the parent? If I have a bunch of text fields on the page like</p> <pre class="lang-html prettyprint-override"><code>&lt;input ng-model="descriptions.test"/&gt; </code></pre> <p>It works works except with the fields generated by the select box.</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.
