A directive to ease the use of ng-options with objects.
When using ng-options with objects, the directive is using reference comparison to find the selected option through the list. Given that, if we are in a application that is getting the list of options and the selected option through outside resources, it does not perform as one would hope.
A workaround for that would be to use a field such as an id and then reselect the data. In some applications, it might feel a bit cumbersome. Hence this directive.
<body ng-app="Demo">
<div ng-controller="DemoCtrl">
<select options-proxy ng-model="selectedValue" ng-options="opt.name for opt in options"></select>
<p ng-bind="selectedValue|json"></p>
</div>
<script type="text/javascript">
app = angular.module('Demo', ['options-proxy']);
app.controller('DemoCtrl', function($scope) {
$scope.options = [{name: 'option1'}, {name: 'option2'}];
$scope.selectedValue = {name: 'option2', extra: 'extra data'};
});
</script>
</body>
