角度指令 ng-repeat 和范围问题

Question

I have some troubles. In directive commentsFeedback in ng-repeat I'm showing some user comments. In form after click in response i get new object from server . I'm updating $scope.users[0].atrb to response.result but ng-repeat in directive don't rewrite this updates.

myApp.controller('myCtrl', ['$scope', '$http', 'Myfactory',
    function ($scope, $http, Myfactory){
    $scope.commentFunk = function(comment, commentForm){
        $http.post('url/', {text: comment.text})
            .success(function (response) {
                $scope.users[0].atrb = response.result;
            })
            .error(  function (response) {
                console.log('Response', response);
            })
    }
}]);
myApp.directive('commentsFeedback', function () {
    return {
        restrict: 'AE',
        template: "<h2>Comments</h2>" +
        "<div ng-repeat='key in some_list'>" +
        "<div ng-repeat='item in key.comments_list'><h4>{$ key.name $}</h4> <b>{$ item.author $}:</b> {$ item.text $}" +
        "</div></div>",
        link:function (scope, element, attrs){
            scope.some_list = scope.users[0].atrb;
        }
      }
   });

How to re shown elements in directive after getting response from server or how to update elements in directive after scope.users[0].atrb have been changed?

Answer 1

Try just to don't reassign scope.users[0].atrb to scope.some_list and use it directly in ng-repeat . Like so: <div ng-repeat='key in users[0].atrb'> . Or may be you just can assign response.result to both users[0].atrb and some_list (I'm just not sure what behind the piece of code you presented here)? Otherwise I suppose you'll have to use $watch as you described in your comment.
