CakePHP 2.x 的视图中未显示验证错误消息

Question

我已经在互联网和 Stack Overflow 上搜索了我的问题，但似乎没有任何效果。这就是我提出这个问题的原因。

我在 CakePHP 中创建了一个表单，但是当我单击提交按钮并且验证中出现错误时，我只看到错误 $this->Flash->error(__('Not all fields are filled in.')); 在视图中创建。 所有输入的数据都已被删除，我没有看到输入字段中的验证错误。

如果我不正确，保存功能应该会在视图中生成错误。

验证失败的原因是什么？

这是我的客户模型：

class Respondent extends AppModel {
    public $validate = array(
    'customer_id' => array(
        'numeric' => array(
            'rule' => array('numeric'),

            //'required' => false,

我的客户控制器：

    debug($user);

    if(isset($user['Customer']['is_logged']) && $user['Customer']['is_logged']=== true ) {
        if ($user['Customer']['accept_invitation'] === 0) {
            $this->redirect(array('controller' => 'customers','action' => 'notaccepted'));
        } else {
            $this->redirect(array('controller' => 'customers','action' => 'accepted'));
        }
    }
    //set var
    $this->set(compact('userid'));

}

public function save() {
    //save data from user in db
    if ($this->request->is('post')) {
        $this->Customer->create();

        if ($this->Customer->save($this->request->data)) {

            if ($this->data['Customer']['accept_invitation'] == 0 ) {

                $this->redirect(array('action' => 'no'));
            } else {

                $this->redirect(array('action' => 'yes'));
            }
            $this->Flash->success(__('The customer has been saved.'));
        } else {
            $this->Flash->error(__('Not all fields are filled in.'));

            $this->redirect(array('action' => 'register'));

如果发生验证错误，请勿重定向。通过写入检查数据是否有效

if($this->Model->validates()){
     //save
}else{
     // set error in flash and do not redirect, let the view rendered. It will show error
}
