Angularjs承诺不绑定到模板在1.2

升级到1.2之后，我的服务返回的promise具有不同的行为… @H_404_1@简单服务myDates：

getDates: function () {
           var deferred = $q.defer();

            $http.get(aGoodURL).
                 success(function (data,status,headers,config) {
                     deferred.resolve(data);  // we get to here fine.
            })......

在早期版本中我只能做，在我的控制器：

$scope.theDates = myDates.getDates();

并且从getDates返回的promise可以直接绑定到Select元素。@H_404_1@现在这不工作，我被迫提供一个回调的promise在我的控制器或数据不绑定：

$scope.theDates = matchDates.getDates();
$scope.theDates.then(function (data) {
      $scope.theDates = data;  // this wasn't necessary in the past

文档仍然说：

$ q promises由模板引擎在角度中识别，这意味着在模板中，您可以将附加到作用域的promise视为结果值。

他们(承诺)在旧版本的Angular工作，但在1.2 RC3自动绑定失败在所有我简单的服务….任何想法，我可能会做错了。

1.2.0-rc3有一些变化，包括你提到的一个：

AngularJS 1.2.0-rc3 ferocIoUs-twitch fixes a number of high priority@H_404_1@ issues in $compile and $animate and paves the way for 1.2.@H_404_1@ This release also introduces some important breaking changes that in some cases could break your directives and templates. Please@H_404_1@ be sure to read the changelog to understand these changes and learn@H_404_1@ how to migrate your code if needed.@H_404_1@ For full details in this release,see the 07000.

更改日志中有描述：

$parse:

due to 07001,$parse and templates in general will no longer automatically unwrap promises. This feature has been deprecated and@H_404_1@ if absolutely needed,it can be reenabled during transitional period@H_404_1@ via $parseProvider.unwrapPromises(true) api.

due to 07002,feature added in rc.2 that unwraps return values from functions if the values are promises (if promise unwrapping is enabled – see prevIoUs point),was reverted due to breaking a popular usage pattern.
