Sorting 带有参数的余烬模型查找查询不'；分页时不显示

2我有一个Ember应用程序，它连接到一个api，从那里可以获取文章。我利用分页来获得每个请求10篇文章。这很有效。但现在我想在请求中添加排序。我通过使用store.find中的额外参数实现了这一点

但是，由于某种原因，如果我使用“returnthis.store.find（'article'，params）；”而不是“返回this.store.find（'article'）；”getMore函数中的新项目（仍被请求并正确添加到存储！）未显示或呈现。但当我从模型中的store.find中删除params参数时，它确实起作用。这里可能是什么情况

模板/文章.hbs

<script type="text/x-handlebars" data-template-name="articles">

      {{#each itemController="article"}}

          <div class="item">
              //...
          </div>
      {{/each}}

    </script>

我脑子里没有什么聪明的想法，但也许是

你有一句话：

if (meta.hasmore) {

---

在

getMore（）函数中。是不是在一个响应中有了这个
meta
字段，而在另一个响应中忘记了它？
否，没有任何改变。行：controller.set（'page'，controller.get（'page'）+1）；已正确执行，但添加到存储区的项目没有显示。hbs中的表是如何实现的？也许你只是缺少合适的听众？我把它插入了我的帖子。我的{{{#each}实现是否正确？因为它应该侦听存储更改，对吗？
