角度控制器加载但不显示ng-repeat(Angular controller loads but ng-repeat doesn't show)

 我正在学习angularJS，我在尝试使用ng-repeat时遇到了问题。我知道模板和控制器正在加载，因为我做了一个console.log（self.post）测试，显示了我期望的单个帖子demoSuggestions和模板加载我期望的comCtrl.post.title。 但是comCtrl.post.comments中的ng-repeat ='注释没有显示任何内容。 关于我做错了什么的任何想法？ 
 
 HTML 
 
<script type='text/ng-template' id='/suggestions.html'>
  <div class='row' ng-controller='commentsController as comCtrl'>
    <div class='col-xs-12'>
        <div class='commentTitle'>
            <h3 class='text-center'>{{comCtrl.post.title}}</h3>
        </div><!--End of commentTitle-->
    </div><!--End of col-->
  </div><!--End of row-->
  <div class='row' ng-repeat='comment in comCtrl.post.comments'>
      <div class='col-xs-12 col-sm-10 col-sm-offset-1'>
          <div class='commentContainer'>
              <div class='row'>
                  <div class='col-xs-3 col-sm-2 col-md-1'>
                      <div class='thumbsUp'>

 模块和配置 
 
var suggestionApp = angular.module('suggestionBox', ['ngRoute'])
.config(['$routeProvider', function ($routeProvider) {
  $routeProvider
    .when('/', {
      templateUrl: '/home.html',
    })
    .when('/suggestion/:id',{
      templateUrl:'/suggestions.html'
    })
    .otherwise({
        redirectTo:'/'
    });
}]);
 
 控制器和服务

    var self = this;
    var swap = 1;
    self.post = suggestions.posts[$routeParams.id];
    console.log(self.post)
    self.addComment = function() {

I'm learning angularJS and I'm having an issue trying to use ng-repeat.I know that the template and controller are loading because I did a console.log(self.post) test that shows the single post that I expect from the demoSuggestions and the template loads the comCtrl.post.title that I expect. But the ng-repeat='comment in comCtrl.post.comments doesn't show anything. Any ideas as to what I'm doing wrong?
