CakePHP HABTM 数据未保存

Question

我有一个 HABTM 关联，​​但无法将数据保存到连接表中。

这是我的 Controller :

    public function create($id)
    {   

     if (!is_numeric($id)) throw new BadMethodCallException('I need an ID');
     $this->Invoice->id = $id;
     if (!$this->Invoice->exists()) throw new NotFoundException('Invalid ID');

    $this->set('invoice_id',$id);

    $names = $this->Invoice->find('list',array(
    'fields'=>array('template_id'),
    'conditions'=>array('id'=>$id)));

    $fields = $this->Field->find('all', array(
     'conditions'=>array(
     'template_id'=>$names)));

    $this->set(compact('fields'));

    $this->set('name',$names);
    $this->Invoice->create();
    if(empty($this->data)){
        $this->data= $this->Field->read($fields);
    } 
    else{
        if(($this->Invoice->saveAll($this->data)))
        {       
            $this->Session->setFlash('The field has been updated');
            $this->redirect(array('controller'=>'invoices', 'action'=>'index'));

        }
        }
}

这里是表格:

<?php echo $this->Form->create('Invoice'); ?>
    <?php foreach ($fields as $field): ?>
    <?php echo debug($field);?>
    <?php echo $this->Form->Input($field['Field']['name'], array('default' =>$field['Field']['default_value'])); ?>
    <?php endforeach ;?>
    <?php echo $this->Form->End('Submit');?>

当我调试 $field 时，我得到:

有一个fields表，其中包含 -

id, name, default_value, template_id, active

<小时/>

有一个发票表，其中包含 -

id、sender_id、receiver_id、template_id、事件

有一个 fields_invoices 表，其中包含 - id、invoice_id、field_id、entered_value

从函数和 View 中，我需要保存发票 ID、字段 ID 和表单中输入的值。

这是否也可以通过使用以下代码代替 $this->Invoice->saveAll(..) 来完成:

if(($this->Invoice->saveAssociated($this->data, array('deep'=> true))))

    {       
        $this->Session->setFlash('The field has been updated');
        $this->redirect(array('controller'=>'invoices', 'action'=>'index'));

    }

关于saveAssociated的信息，来自公认令人困惑的文档。
