用cakephp保存相对值

Question

In MySQL I can do the following: 在MySQL中，我可以执行以下操作：

UPDATE table SET field=field+1 WHERE id=123

How do I do the same while using the CakePHP approach? 使用CakePHP方法时该如何做？

Tried the following: 尝试了以下内容：

$this->Model->id = 123;
$this->Model->save(array(
    'field' => '`field`+1',
));

The article saving-your-data.html doesn't seem to cover that. 文章save-your-data.html似乎没有涵盖这一点。

Also searched for cakephp+update+relative , found nothing relevant. 还搜索cakephp + update + relative ，没有发现任何相关内容。

UPDATE Right now I'm doing a direct update, it works but I was thinking there might be a better way 更新现在我正在直接进行更新，它可以工作，但是我认为可能会有更好的方法

$this->Model->query("UPDATE ".$this->Model->useTable." SET field=field+1 WHERE id=123");

Answer 1

$this->Model->updateAll(  
         array('Model.count' => 'Model.count + 1'),  
         array('Model.id' => 1)  

  );
