phalcon 中更新記錄的唯一性驗證

Question

我使用 phalcon 框架來構建 rest api .. 我構建了所有 CRUD 函數，但是在使用更新時我無法更新記錄，因為驗證失敗，因為電子郵件是唯一的..我想通過跳過唯一驗證來更新此記錄..這是我的驗證：

class UpdateUserValidation extends Validation
{
public function initialize()
{

$this->add(
        'email', 
        new Uniqueness([
        "model"   => new Users,
            "message" => ": email already exist",
        ]));
}}

這是我在控制器中的功能：

public function updateAction($id)
    {
$validation = new UpdateUserValidation;
        $messages = $validation->validate($_POST);
if (count($messages) > 0 ) {
            $all_errors = array();
             foreach ($messages as $message) {
        array_push($all_errors, $message->getMessage());
              
             }

$this->response->setStatusCode(422,'Validation Error');
    $this->response->setJsonContent(array('Message' => $all_errors));
        return $this->response; 
}

任何幫助請

它沒有很好的文檔記錄，但是如果您使用當前行實例（模型）進行驗證，則該記錄將被忽略。

// get record
    $user = Users::findFirst([
        'email = :email:',
        'bind' => [
            'email' => 'info@test.com',
        ],
    ]);

// validation
    $this->add('email', new Uniqueness([
        'model'   => $user,
        'message' => ':email already exist',
    ]));

    $messages = $this->validate([
        'email' => 'info@test.com',
    ]);
    // success, because added current record

    $messages = $this->validate([
        'email' => 'existing@email.com',
    ]);
    // fails, a record with this email already exists

// save
    if(!$messages) {
        $user->save([
            'email'  => 'info@test.com',
        ]);
    }
