mongodb - AngularJS + MongoLab JSON 响应未显示在视图中

Question

我编写了一个基本的 angularJS + mongoLab 应用程序。获取数据的代码工作正常，在 Chrome 开发者工具中我可以看到响应为：

[ { "_id" : { "$oid" : "5166c406e4b08774fa6844a9"} , "tag" : "Software Developer"} , { "_id" : { "$oid" : "51679cbde4b05c7db8d21e70"} , "tag" : "Project Management"} ]

在我看来，我有：

<ul>
                <li ng-repeat="tagz in tags">
                    {{tagz.tag}}
                </li>
            </ul>

但是当我在浏览器上显示时，我看到的只是

点，但不显示标签值。我的控制器有：

'use strict';
// Define our root-level controller for the application.
        Riadd.controller(
            "AppController",
            function( $scope, $route, $routeParams, Tags){




                // Update the rendering of the page.
                var render = function(){
                    $scope.tags = Tags;

                    // Pull the "action" value out of the
                    // currently selected route.
                    var renderAction = $route.current.action;

                    // Also, let's update the render path so that
                    // we can start conditionally rendering parts
                    // of the page.
                    var renderPath = renderAction.split( "." );

                    // Grab the username out of the params.
                    //
                    // NOTE: This will be undefined for every route
                    // except for the "contact" route; for the sake
                    // of simplicity, I am not exerting any finer
                    // logic around it.
                    var username = ($routeParams.username || "");

                    // Reset the booleans used to set the class
                    // for the navigation.
                    var isHome = (renderPath[ 0 ] == "home");
                    var isFriends = (renderPath[ 0 ] == "friends");
                    var isContact = (renderPath[ 0 ] == "contact");

                    // Store the values in the model.
                    $scope.renderAction = renderAction;
                    $scope.renderPath = renderPath;
                    $scope.username = username;
                    $scope.isHome = isHome;
                    $scope.isFriends = isFriends;
                    $scope.isContact = isContact;

                };

                // Listen for changes to the Route. When the route
                // changes, let's set the renderAction model value so
                // that it can render in the Strong element.
                $scope.$on(
                    "$routeChangeSuccess",
                    function( $currentRoute, $previousRoute ){

                        // Update the rendering.
                        render();

                    }
                );

            }
        );

知道我哪里出错了吗？

请参考https://github.com/pkozlowski-opensource/angularjs-mongolab-promise/blob/master/README.md

恕我直言，而不是

$scope.tags = Tags;

你会需要

Tags.all(function(tags){
  $scope.tags = tags;
});
