php - cakephp 与 order by 的匹配不起作用

Question

我正在尝试订购我的分页结果。但它不起作用。

$this->paginate = array(
                'limit' => 15,
                'fields' => array('*', "MATCH (headline, author, short_headline, subline, teaser, text) AGAINST ('$var') AS score"),
                'conditions' =>  "MATCH(headline, author, short_headline, subline, teaser, text) AGAINST('$var' IN BOOLEAN MODE)",
                'order' => array('score' => 'desc')
            );

查询看起来像:

SELECT *, MATCH (`headline`, `author`, `short_headline`, `subline`, `teaser`, `text`) AGAINST ('herz tod') AS `score`, `Story`.`id` FROM `fates`.`stories` AS `Story` WHERE MATCH(headline, author, short_headline, subline, teaser, text) AGAINST('herz tod' IN BOOLEAN MODE) LIMIT 15

并且按分数排序消失了!我做错了什么？感谢您的帮助!

Answer 1

尝试在尝试分页之前将 score 设为 virtualField，以便使用它来对分页进行排序。 (可能还有其他方法可以让它按分数排序，但我不知道它们。)

$this->Model->virtualFields['score'] = "MATCH (headline, author, short_headline, subline, teaser, text) AGAINST ('" . Sanitize::escape($var) . "')";

我还想指出，以防万一，如果您不能假设 $var 到是值得信赖的数据，例如 $var 来自用户输入。
