cakephp更新字段

Question

如何强制蛋糕更新字段而不插入新记录.

如果db中不存在id,它应该失败

我发现强制插入我可以这样做'updated' => false,如果我这样做'updated' => true它会工作

Answer 1

如果您只想更新字段,请使用saveField模型的方法

$this->Order->id    = $id;
$this->Order->saveField('status', 'VOID');

参考:http://book.cakephp.org/2.0/en/models/saving-your-data.html

Answer 2

//Create: id isn't set or is null
$this->Recipe->create();
$this->Recipe->save($this->data);

//Update: id is set to a numerical value 


$this->Recipe->id = 2;
$this->Recipe->save($this->data);
