假设我有两个模型：文章和评论(1篇文章x N条评论),我想显示文章的分页列表,包括每个文章的评论数量.我有这样的事情：

控制器：

$this->paginate = array('limit'=>80,'recursive'=>-1,'fields'=>array("Article.*","COUNT(Comment.id) as nbr_comments"),'joins'=>array(array(   'table' => 'comments','alias' => 'Comment','type' => 'LEFT','conditions' => array('Comment.article_id = Article.id'))
                                            ),'group'=>"Article.id"
                        );

(我不得不覆盖findCount()方法,以便使用group by进行分页)

问题是在视图中,sort()方法不起作用：

<th><?PHP echo $this->Paginator->sort('nbr_comments');?></th> //life is not that easy

我能够通过“欺骗”分页和排序来创建一个解决方法：

调节器

$order = "Article.title";
$direction = "asc";
if(isset($this->passedArgs['sort']) && $this->passedArgs['sort']=="nbr_comments")
    $order = $this->passedArgs['sort'];
    $direction = $this->passedArgs['direction'];
    unset($this->passedArgs['sort']);
    unset($this->passedArgs['direction']);
}
$this->paginate = array(... 'order'=>$order." ".$direction,...);
$this->set('articles',$this->paginate());
if($order == "clicks"){
    $this->passedArgs['sort'] = $order;
    $this->passedArgs['direction'] = $direction;
}

视图

<?PHP $direction = (isset($this->passedArgs['direction']) && isset($this->passedArgs['sort']) && $this->passedArgs['sort'] == "nbr_comments" && $this->passedArgs['direction'] == "desc")?"asc":"desc";?>
<th><?PHP echo $this->Paginator->sort('Hits','clicks',array('direction'=>$direction));?></th>

它的工作原理……但似乎对于开发者应该透明的东西来说代码太多了. (感觉我正在做蛋糕的工作)所以我问是否还有另一种更简单的方法.也许蛋糕有这个功能,但决定隐藏它.. o_O ..在文档上没有关于这个,我还没有找到另一个关于S.O的好解决方案……你是怎么做到的？

提前致谢！
