php - cakephp 验证规则不保留提交

Question

用户模型

//...

public $validate = array(
    "username" => array(
        "alpha-numeric" => array(
            'rule'     => 'alphaNumeric',
            'required' => true,
            'message'  => 'Username must contain only numbers and letters.'                 
        ),
        "between" => array(
            "rule" => array("between", 4, 25),
            "message" => "Username must contain between 4 to 25 characters."
        )
    ),

//...

用户控制器

public function index() {
    debug($this->data); // displays values as expected
    debug($this->User->validates()); // always false, unless I remove alphanumeric rule
}

提交时，username无论文本中包含什么内容，我的表单都会始终将该字段验证为 false（触发其相​​应的消息）。其余字段也未验证。如果我username一起删除验证规则，其余字段仍未验证。（提交表格如同经过验证）

我在这里想念什么？

在手动调用之前$this->User->validates()，您必须调用模型的set方法并提供表单的数据。

public function index() {
    $this->User->set($this->request->data); // Only way the next method will work.
    debug($this->User->validates());
}
