CakePHP SQL查詢計數以獲得最大查看量

如何計算查看量以便我可以根據流行度進行顯示，即誰擁有最高查看次數以便先顯示等。哪個場所的評價最高，它會先顯示，然後是其他顯示。我已經嘗試過，但它不起作用。CakePHP SQL查詢計數以獲得最大查看量

在這裏，我做了簡單地寫在給定控制器的型號。我發現這個使用CakePHP的「Virtualfield」的概念做到這一點的最好辦法2線路編碼。

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

使用Virtualfield概念後，它似乎太容易了。

這裏的結果會像這樣

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 
       ) 
     )

在這裏，人們可以很容易找到的評論的一定的id nunber。謝謝
