CakePHP SQL查询计数以获得最大查看量

如何计算查看量以便我可以根据流行度进行显示，即谁拥有最高查看次数以便先显示等。哪个场所的评价最高，它会先显示，然后是其他显示。我已经尝试过，但它不起作用。CakePHP SQL查询计数以获得最大查看量

在这里，我做了简单地写在给定控制器的型号。我发现这个使用CakePHP的“Virtualfield”的概念做到这一点的最好办法2线路编码。

var $virtualFields = array(
    'review_count' => 'SELECT COUNT(*) FROM reviews as Review WHERE Review.venue_id = Venue.id' 
);

使用Virtualfield概念后，它似乎太容易了。

这里的结果会像这样

Array 
(
    [0] => Array 
     (
      [Venue] => Array 
       (
        [id] => 6 
        [review_count]=> 3 
       ) 
     ) 
[1] => Array 
     (
      [Venue] => Array 
       (
        [id] => 15 
        [review_count]=>2 
       ) 
     ) 
[2] => Array 
     (
      [Venue] => Array 
       (
        [id] => 17 
        [review_count]=>1 
       ) 
     ) 
[3] => Array 
     (
      [Venue] => Array 
       (
        [id] => 31 
        [review_count]=>0 
       ) 
     ) 
[4] => Array 
     (
      [Venue] => Array 
       (
        [id] => 32 
        [review_count]=>5 
       ) 
     )

在这里，人们可以很容易找到的评论的一定的id nunber。谢谢
