将数据更新到CakePHP中另一个模型的关联模型

Question

我创建了一堆代码，它将更新另一个模型的关联模型的字段。

我有3种型号：

1. Review 
2. Application 
3. Stat 

在我ReviewsController.php

  foreach ($this->request->data['Review']['Mentee'] as $mentee) { 

       $this->loadModel('Application'); 
       $this->Application->id = $mentee; 
       pr($this->Application); 
       $this->Application->Stat->saveField('second_video_observation_completed', $this->request->data['Review']['third_video_setting']); 
      } 

我试图更新second_video_observation_completed场Stat型号

PR输出$this->Application

和Pr输出$this->Application->Stat

我通过DebugKit检查SQL日志，但它插入新记录，而不会更新Application w/ id 858记录的相关Stat。

INSERT INTO `ntc_development`.`stats` (`second_video_observation_completed`, `modified`, `created`) VALUES ('0', '2014-04-23 07:49:58', '2014-04-23 07:49:58') 

Answer 1

要在Stat模型中使用saveField您需要设置id为Stat模型不Application模型。

$this->Application->Stat->id = 'YOUR_ID'; 
$this->Application->Stat->saveField('second_video_observation_completed', $this->request->data['Review']['third_video_setting']);
