angularjs $ scope not working

Question

经过几次教程视频和文档后，我的数据绑定似乎没有生效。我对这门语言比较陌生，所以有人可以向我解释我做错了什么吗？ （我尝试使用$ scope实现，而不是作为我的控制器的别名）。我附上了我的HTML和我的javascript。

    <div class="container">
    <div class="row row-content" ng-controller="DishDetailController">
        <div class="col-xs-12">
           <div class="media-list">
                <div class="media-left media-middle">
                    <a href="#">
                    <img class="media-object img-thumbnail"
                     ng-src={{dish.image}} alt="Uthappizza">
                    </a>
                </div>
                <div class="media-body">
                    <h2 class="media-heading">{{dish.name}}
                     <span class="label label-danger">{{dish.label}}</span>
                     <span class="badge">{{dish.price | currency}}</span></h2>
                    <p>{{dish.description}}</p>
                    <br><br>
                    <p> <strong>Customer Comments</strong> &nbsp;&nbsp;&nbsp;&nbsp;  Sort by:
                       <input type="text" ng-model="userOrder" accept="" placeholder="Filter by" autofocus></p>
                    <span>{{dish}}</span>
                </div>
        </div>
        </div>
        <div class="col-xs-9 col-xs-offset-1">
             <div class="media-list" ng-repeat="comment in dish.comments | orderBy:userOrder">
                 <ul>
                <blockquote>
                  <p>{{comment.rating}} Stars</p>
                   <p>{{comment.comment}}</p>
                    <footer>By {{comment.author}} on {{comment.date | date:'mediumDate'}} </footer>
                </blockquote>
                </ul>
        </div>
    </div>

        .controller('DishDetailController', ['$scope', function($scope) {

        $scope.dish={
                      name:'Uthapizza',
                      image: 'images/uthapizza.png',
                      category: 'mains',

    }])

Answer 1

您的对象在数组中，因此表达式需要以这种方式访问​​它们。

示例，访问comment数组中的第二个comments：

<footer>By {{comment.author}} on {{comment.date | date:'mediumDate'}} </footer>

应该是：

<footer>By {{comments[1].comment.author}} on {{comments[1].comment.date | date:'mediumDate'}} </footer>

编辑：正如已经指出的那样，已经有一个转发器（我忽略了）。这个答案没有实际意义。
