cakephp usermin密码未保存

我正在尝试编辑公司并更新umusers表中的密码。如果我使用save，它会更新公司，但不会更新umusers表中的密码。如果我使用saveAll，它会在umusers表中创建一个新用户

这是我的设置

公司模式我有：

    public $hasOne = 'Umuser';

公司控制人

public function edit($id = null) {
    $this->Company->id = $id;
    if (!$this->Company->exists()) {
        throw new NotFoundException(__('Invalid company'));
    }
    if ($this->request->is('post') || $this->request->is('put')) {
        if ($this->Company->save($this->request->data)) {
            $this->Session->setFlash(__('The company has been saved'));
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The company could not be saved. Please, try again.'));
        }
    } else {
        $this->request->data = $this->Company->read(null, $id);
    }

}

$this->request->data的var\u转储：

array(2) { ["Company"]=> array(12) { ["id"]=> string(3) "157" ["member_number"]=> string(6) "234234" ["name"]=> string(5) "keith" ["address1"]=> string(5) "keith" ["address2"]=> string(5) "keith" ["county"]=> string(5) "keith" ["limited"]=> string(1) "0" ["tax_number"]=> string(5) "keith" ["contact_name"]=> string(5) "keith" ["phone"]=> string(5) "keith" ["email"]=> string(15) "keith@keith.com" ["payment_start"]=> array(3) { ["month"]=> string(2) "02" ["day"]=> string(2) "01" ["year"]=> string(4) "2013" } } ["Umuser"]=> array(1) { ["password"]=> string(6) "keith1" } }

我知道目前我并没有对密码进行哈希运算，也没有在密码留空时将其取消设置。我遗漏了什么，可能与id有关？

请确保您已将id作为隐藏字段传递到编辑表单中

    In this you need to get the "umuser id" & specify the id value as below..
     {
        ["Company"]=> {
            ["id"]=> "157" 
             ......
        }
        ["Umuser"] => {
            ["id"]=> "some value"
            ["password"]=> "keith1"
        }
     } 

echo $this->Form->input('id', array('type' => 'hidden'));

save（）

中发生了什么？另外，数据库中的密码是什么字段类型的？这是我发布的var_dump数据
