Arrays 错误：[filter:notarray]应为数组，但收到了对象

嗨，我正在尝试创建一个基本的全局搜索，它将根据当前的视图（控制器）过滤页面上的结果

       <div class="card-image waves-effect waves-block waves-light">
         <img class="activator" src="images/sample-1.jpg">
       </div>
       <div class="card-content">
         <span class="card-title activator grey-text text-darken-4">{{post.Title}}<i class="material-icons right">more_vert</i></span>
         <p><a href="#">Read More</a></p>
         <p>By: {{post.Author}} &nbsp; Published on: {{post.Published | date:'mediumDate'}}</p>
       </div>
       <div class="card-reveal">
         <span class="card-title grey-text text-darken-4">{{post.Title}}<i class="material-icons right">close</i></span>
         <div>{{post.Intro}}</div>
         <p ng-bind-html="post.Body">{{post.Body}}</p>
       </div>
   </div>
</div>

搜索控制器：

    <form ng-controller="searchCtrl">
      <div class="container col-md-12">
        <div class="row margin col-md-2">
        <label>Search</label>
        <input ng-model="searchSite" type="text" class="form-control" />
      </div>
      </div>
  </form>

controllersModule.controller('BlogCtrl', ["$scope", "postsDB", function($scope, postsDB) {



//postsDB is the factory pulling the API
        postsDB.query(function(posts){
             $scope.myPosts = posts;
         })
}]);

       <div class="card-image waves-effect waves-block waves-light">
         <img class="activator" src="images/sample-1.jpg">
       </div>
       <div class="card-content">
         <span class="card-title activator grey-text text-darken-4">{{post.Title}}<i class="material-icons right">more_vert</i></span>
         <p><a href="#">Read More</a></p>
         <p>By: {{post.Author}} &nbsp; Published on: {{post.Published | date:'mediumDate'}}</p>
       </div>
       <div class="card-reveal">
         <span class="card-title grey-text text-darken-4">{{post.Title}}<i class="material-icons right">close</i></span>
         <div>{{post.Intro}}</div>
         <p ng-bind-html="post.Body">{{post.Body}}</p>
       </div>
   </div>
</div>

博客控制器：

    <form ng-controller="searchCtrl">
      <div class="container col-md-12">
        <div class="row margin col-md-2">
        <label>Search</label>
        <input ng-model="searchSite" type="text" class="form-control" />
      </div>
      </div>
  </form>

controllersModule.controller('BlogCtrl', ["$scope", "postsDB", function($scope, postsDB) {



//postsDB is the factory pulling the API
        postsDB.query(function(posts){
             $scope.myPosts = posts;
         })
}]);

       <div class="card-image waves-effect waves-block waves-light">
         <img class="activator" src="images/sample-1.jpg">
       </div>
       <div class="card-content">
         <span class="card-title activator grey-text text-darken-4">{{post.Title}}<i class="material-icons right">more_vert</i></span>
         <p><a href="#">Read More</a></p>
         <p>By: {{post.Author}} &nbsp; Published on: {{post.Published | date:'mediumDate'}}</p>
       </div>
       <div class="card-reveal">
         <span class="card-title grey-text text-darken-4">{{post.Title}}<i class="material-icons right">close</i></span>
         <div>{{post.Intro}}</div>
         <p ng-bind-html="post.Body">{{post.Body}}</p>
       </div>
   </div>
</div>

HTML输出

       <div class="card-image waves-effect waves-block waves-light">
         <img class="activator" src="images/sample-1.jpg">
       </div>
       <div class="card-content">
         <span class="card-title activator grey-text text-darken-4">{{post.Title}}<i class="material-icons right">more_vert</i></span>
         <p><a href="#">Read More</a></p>
         <p>By: {{post.Author}} &nbsp; Published on: {{post.Published | date:'mediumDate'}}</p>
       </div>
       <div class="card-reveal">
         <span class="card-title grey-text text-darken-4">{{post.Title}}<i class="material-icons right">close</i></span>
         <div>{{post.Intro}}</div>
         <p ng-bind-html="post.Body">{{post.Body}}</p>
       </div>
   </div>
</div>

将其转换为数组的原因是，我得到了错误

error:[filter:notarray]预期的数组

，但即使更改了它，我仍然会得到相同的错误

       <div class="card-image waves-effect waves-block waves-light">
         <img class="activator" src="images/sample-1.jpg">
       </div>
       <div class="card-content">
         <span class="card-title activator grey-text text-darken-4">{{post.Title}}<i class="material-icons right">more_vert</i></span>
         <p><a href="#">Read More</a></p>
         <p>By: {{post.Author}} &nbsp; Published on: {{post.Published | date:'mediumDate'}}</p>
       </div>
       <div class="card-reveal">
         <span class="card-title grey-text text-darken-4">{{post.Title}}<i class="material-icons right">close</i></span>
         <div>{{post.Intro}}</div>
         <p ng-bind-html="post.Body">{{post.Body}}</p>
       </div>
   </div>
</div>
