【问题描述】：

我尝试使用“hasMany through”模型通过一个查询保存多个数据。 返回 $this->request->data 的值表明：

Array
(
[Order] => Array
    (
        [id] => 
        [customer_id] => 4711
        [orderDate] => Array
            (
                [month] => 01
                [day] => 14
                [year] => 2014
            )
        ... 
    )

[ArticleOrder] => Array
    (
        [article_id] => Array
            (
                [0] => 2002
            )

        [quantity] => Array
            (
                [0] => 99
            )

    )

)

数组 [ArticleOrder] 尚未保存在数据库中。在我的控制器中，我尝试了 saveAll (yes deep => true)、saveMany、saveAssociated...

这里是控制器：

public function add() 
    $this->set('customers', $this->Order->Customer->find('list')); //Auflösung der Schlüssel
    //$this->set('articles', $this->Order->ArticleOrder->Article->find('list'));
    if(!empty($this->request->data)) 
        $this->Order->create();
        pr($this->data);
        if($this->Order->ArticleOrder->saveAll($this->request->data, array('deep' => true)))           
            $this->Session->setFlash("Die Bestellung wurde gespeichert!");
            $this->redirect(array('action'=>'index'));
         else 
            $this->Session->setFlash('Die Bestellung konnte nicht gespeichert werden.');
                   
    

请帮帮我……我很绝望……

【参考方案1】：

数组错了？我认为它应该是这样的：

'ArticleOrder' => array(
    array('article_id' => 2002, 'quantity' => 99),
    array('article_id' => 3151, 'quantity' => 14),
    /* ... */
);

检查生成表单或数据结构的代码。

见http://book.cakephp.org/2.0/en/models/saving-your-data.html#model-savemany-array-data-null-array-options-array

【参考方案2】：

我解决了问题:-)

这是控制器的代码：

    public function add() 
    $this->set('customers', $this->Order->Customer->find('list')); //Auflösung der Schlüssel
    //$this->set('articles', $this->Order->ArticleOrder->Article->find('list'));
    if(!empty($this->request->data)) 
        $this->Order->create();
        $data = array(
            'Order' => $this->request->data['Order'],
            'ArticleOrder' => array()
        );  
        for($i = 0; $i< count($this->request->data['ArticleOrder']['article_id']); $i++) 
            $data['ArticleOrder'][] = array(
                'article_id' => $this->request->data['ArticleOrder']['article_id'][$i],
                'quantity' => $this->request->data['ArticleOrder']['quantity'][$i]
            );
                   
        if($this->Order->saveAssociated($data, array('deep'=>true)))           
            $this->Session->setFlash("Die Bestellung wurde gespeichert!");
            $this->redirect(array('action'=>'index'));
         else 
            $this->Session->setFlash('Die Bestellung konnte nicht gespeichert werden.');
        
    

我刚刚在for-block中格式化了数组

谢谢
