ui-select2 and ng-required

Question

我在ui-select2组件中使用require/ng-require有问题。出于可重用性的原因，我将ui-select2封装在自定义指令中，但无法获得所需的工作

这是活塞:http://plnkr.co/edit/2NaGvDWoEw14BN2few9W?p=preview

尝试没有指令，它的工作:http://plnkr.co/edit/uE698iFcUNnsYVF2fkOO?p=preview

问题是angular不支持动态表单元素:

第1404期https://github.com/angular/angular.js/issues/1404

解决方法(直到1.3版本出来):

app.config(['$provide', function($provide) {
$provide.decorator('ngModelDirective', ['$delegate', function($delegate) {
    var ngModel = $delegate[0], controller = ngModel.controller;
    ngModel.controller = ['$scope', '$element', '$attrs', '$injector', function(scope, element, attrs, $injector) {
        var $interpolate = $injector.get('$interpolate');
        attrs.$set('name', $interpolate(attrs.name || '')(scope));
        $injector.invoke(controller, this, {
            '$scope': scope,
            '$element': element,
            '$attrs': attrs
        });
    }];
    return $delegate;
}]);
$provide.decorator('formDirective', ['$delegate', function($delegate) {
    var form = $delegate[0], controller = form.controller;
    form.controller = ['$scope', '$element', '$attrs', '$injector', function(scope, element, attrs, $injector) {
        var $interpolate = $injector.get('$interpolate');
        attrs.$set('name', $interpolate(attrs.name || attrs.ngForm || '')(scope));
        $injector.invoke(controller, this, {
            '$scope': scope,
            '$element': element,
            '$attrs': attrs
        });
    }];
    return $delegate;
}]);
