Step 10: Other ways of including comments in a page

The default implementation of FOSCommentBundle uses asynchronous javascriptand jQuery (optionally with easyXDM for cross domain requests) to load a comment thread into a page.

FOSCommentBundle的缺省实现是使用异步javascript和jQuery（也可以使用easyXDM进行跨域请求）来将评论线索加载到页面。

It is possible to include the thread without using javascript to load it, but needs additional work inside the controller's action.

不使用javascript来引导线索加载也是可以实现的，但需要在控制器的Action中进行额外的工作。

At a minimum, you will need to include the following in your action's PHP code:

至少，您需要在您Action中的PHP代码中包含下列语句：

public function somethingAction(Request $request)
{
    $id = 'thread_id';
    $thread = $this->container->get('fos_comment.manager.thread')->findThreadById($id);
    if (null === $thread) {
        $thread = $this->container->get('fos_comment.manager.thread')->createThread();
        $thread->setId($id);
        $thread->setPermalink($request->getUri());
        // Add the thread
        $this->container->get('fos_comment.manager.thread')->saveThread($thread);
    }
    $comments = $this->container->get('fos_comment.manager.comment')->findCommentTreeByThread($thread);
    return $this->render('AcmeDemoBundle:Controller:something.html.twig', array(
        'comments' => $comments,
        'thread' => $thread,
    ));
}

Once you've included this code in your action, some code must be included in your template:

一旦您已经在您的Action中包含了上述代码，那么也必须在您的模板中包含一些代码：

{% block body %}
{# ... #}
<div id="fos_comment_thread" data-thread="{{ thread.id }}">
{% include 'FOSCommentBundle:Thread:comments.html.twig' with {
    'comments': comments,
    'thread': thread
} %}
</div>
{# ... #}
{% endblock body %}
{% block javascript %}
{# jQuery must be available in the page by this time, and make sure javascript block is after
  <div id="fos_comment_thread"> in the DOM Tree, for example right before </body> tag
#}
{% javascripts '@FOSCommentBundle/Resources/assets/js/comments.js' %}
<script type="text/javascript" src="{{ asset_url }}"></script>
{% endjavascripts %}
{% endblock javascript %}

That is it!
