CakePHP：无论如何要告诉为什么 Model->validates() 返回 false？

Question

如果 Model->validates() 返回 false 有没有简单的方法知道原因？

我正在尝试保存一些数据，但无法保存。事实证明，它也没有验证。如果我关闭验证，它会保存。我需要验证它，但我不知道为什么它没有验证？

我使用了这个代码：

if($this->User->create($user) && !$this->User->validates())
{
    debug($user);
}

所以如果它不验证它会告诉我数据是什么。

它打印出这个：

Array
(
    [User] => Array
        (
            [first_name] => Tim
            [last_name] => Zahn
            [phone] => 8833323235
            [email] => t@z.com
            [password] => ert
        )

    [Confirm] => Array
        (
            [email] => t@z.com
            [password] => ert
        )

)

看起来应该通过验证。

如果需要，我也可以发布我的模型源代码。

更新：

这是模型。我正在使用 multivalidatable 行为。我尝试过使用默认和注册验证集：

class User extends AppModel
{
    var $actsAs = array('Multivalidatable');

    var $hasOne = 'WishList';
    var $hasMany = array(
        'Address' => array(
            'conditions' => array('NOT' => array('Address.deleted' => '1')),
            'order' => array('Address.is_billing DESC')
        )
    );

    var $validate = array(
        'first_name' => array(
            'rule' => 'notEmpty'
        ),
        'last_name' => array(
            'rule' => 'notEmpty'
        ),
        'password' => array(
            'passRule1' => array(
                'rule' => 'notEmpty',
                'message' => 'Please enter a password'
            ),
            'passRule2' => array(
                'rule' => array('identicalFieldValues', 'password'),
                'message' => 'Passwords do not match'
            )
        ),
        'email' => array(
            'emailRule1' => array(
                'rule' => 'email',
                'message' => 'You must specify a valid email address'
            ),
            'emailRule3' => array(
                'rule' => array('identicalFieldValues', 'email'),
                'message' => 'Emails do not match'
            )
        )
    );

    var $validationSets = array(
        'register' => array(
            'first_name' => array(
                'rule' => 'notEmpty'
            ),
            'last_name' => array(
                'rule' => 'notEmpty'
            ),
            'password' => array(
                'passRule1' => array(
                    'rule' => 'notEmpty',
                    'message' => 'Please enter a password'
                ),
                'passRule2' => array(
                    'rule' => array('identicalFieldValues', 'password'),
                    'message' => 'Passwords do not match'
                )
            ),
            'email' => array(
                'emailRule1' => array(
                    'rule' => 'email',
                    'message' => 'You must specify a valid email address'
                ),
                'emailRule2' => array(
                    'rule' => 'isUnique',
                    'message' => 'That email address is already in our system'
                ),
                'emailRule3' => array(
                    'rule' => array('identicalFieldValues', 'email'),
                    'message' => 'Emails do not match'
                )
            )
        ),
        'billing' => array(
            'email' => array(
                'emailRule1' => array(
                    'rule' => 'email',
                    'message' => 'You must specify a valid email address'
                ),
                'emailRule3' => array(
                    'rule' => array('identicalFieldValues', 'email'),
                    'message' => 'Emails do not match'
                )
            )
        )
    );

    public function beforeValidate()
    {
        parent::beforeValidate();

        // if password is empty reset from hash to empty string
        if (isset($this->data['User']['password']) && $this->data['User']['password'] == Security::hash('', null, true)) {
                $this->data['User']['password'] = '';
        }
        return true;
    }

    function identicalFieldValues($field=array(), $compare_field=null)
    {
        foreach ($field as $key => $value)
        {
            $v1 = $value;
            $v2 = $this->data["Confirm"][$compare_field];
            if ($compare_field == 'password' && $v2 != '')
            {
                $v2 = Security::hash($v2, null, true);
            }
            if ($v1 !== $v2)
            {
                return false;
            } 
            else
            {
                continue;
            }
        }
        return true;
    }

}

Answer 1

我会从这样的事情开始：

if($this->User->create($user) && !$this->User->validates())
{
    debug($user);
    debug($this->User->validationErrors);
}

这应该可以准确地告诉您哪些字段或哪些字段未通过验证以及原因。

Answer 2

您是否在验证中设置了一条消息，以便它可以告诉您失败的地方，例如：

'password' => array(
  'rule' => array('minLength', '8'),
  'message' => 'Mimimum 8 characters long'
),

另外，如果你开启了 AUTH，它可能会加密密码。

此外，您应该在尝试创建/保存之前断言 validate。
