Database CakePHP函数不更新表

hi all当尝试更新我的数据库时，此函数不会从表中获取id，也不会更新表中的那一行。它还抛出了一个错误

$this->Relationship->id = $this->request->data['id'];

以下是整个功能

public function approve($id=null){
        $this->Relationship->id = $id;
        if($this->request->is('get')){
        $this->request->data=$this->Relationship->read();}
        $this->Relationship->id = $this->request->data['id'];
        if($this->Relationship->save($this->request->data)) {
        $this->Session->setFlash('Your Relationship has been updated.');
        $this->redirect(array('action' => 'request'));
        } else {
            $this->Session->setFlash('Unable to update your post.');
        }
    }
    }

这是表格/视图

<?php
echo $this->Form->create('Relationship', array('action'=>'approve'));
echo $this->Form->input('expirydate',array('label'=>'Expiry Date: ', 'class' => 'dateclass')); 
echo $this->Form->end('Submit');

?>

我想用这个函数做的是抓取一个id，并编辑该条目中的两个字段

它应该是

$this->request->data['Relationship']['id']如果表单设置正确。而且，你也可以这样做

$this->Relationship->create($this->request->data);
$this->Relationship->save()

我还必须将数据库中的tinyint从0=>1更改为0。我遇到的另一个问题是我的请求视图，它没有将id传递给approve函数。一旦我把代码改成这个，它就工作了

<?php foreach($Relationships as $relationship):?>
                    <tr> 

                        <td align='center'><?php echo $relationship['Relationship']['partyone']; ?></td>
                        <td align='center'><?php echo $relationship['Relationship']['partytwo']; ?></td>
                        <td> </td>
                        <td><?php echo $this->Html->link($relationship['Relationship']['partyone'], array('action'=>'approve', $relationship['Relationship']['id'])); ;?>
                        </td>

                    </tr>
                <?php endforeach; ?>

            </table>

您能详细介绍一下我是如何设置表格的吗？
<?php foreach($Relationships as $relationship):?>
                    <tr> 

                        <td align='center'><?php echo $relationship['Relationship']['partyone']; ?></td>
                        <td align='center'><?php echo $relationship['Relationship']['partytwo']; ?></td>
                        <td> </td>
                        <td><?php echo $this->Html->link($relationship['Relationship']['partyone'], array('action'=>'approve', $relationship['Relationship']['id'])); ;?>
                        </td>

                    </tr>
                <?php endforeach; ?>

            </table>
