Cakephp 3无法识别自定义验证规则方法并且未显示验证消息

第一个问题是我的表中有以下验证器和公共函数

用户表.php*

$validator
        ->scalar('name')
        ->maxLength('name', 45)
        ->requirePresence('name', 'create')
        ->notEmptyString('name', 'You must enter a name for the user.');

   $validator
       ->add('name', 'custom', array('rule' => 'checkExistingUser', 'message' => 'This user already appears to be in the system.', 'on' => 'create'));

   public function checkExistingUser($value,$context)
{
    return $this->find('all', ['conditions' => ['Users.name' => $context['data']['name'], 'Users.user_type_id' => $context['data']['user_type_id']]])->count() < 1 ;

}

保存下面的表单时，收到消息“Method checkExistingUser does not exist”。为什么它无法识别表模型中明确定义的方法？我是否遗漏了什么？

添加.ctp*

<?php echo $this->Form->create($user);?>
    <fieldset>
            <legend><?php echo __('Add User'); ?></legend>
    <?php
            echo $this->Form->control('name', ['type' => 'text']);
        echo $this->Form->control('user_type_id');
    echo $this->Form->control('owner', array('type' => 'text', 'label' => "Owner Name"));
    echo $this->Form->control('owner_contact', array('type' => 'text', 'label' => "Owner Contact (phone, email etc)"));
    echo $this->Form->control('description', ['type' => 'textarea']);
            echo $this->Form->control('ia_exception', array('type' => 'text', 'label' => "IA Exception Number"));
            echo $this->Form->control('is_manual', array('type' => 'checkbox', 'label' => "Password Updated Manually"));
            echo $this->Form->control('Environment', ['type' => 'select', 'multiple' => 'true', 'label' => 'Environment(s)']);
    ?>
    </fieldset>
<div class="buttons">
<?php
echo $this->Form->button('Save', ['type'=> 'submit', 'name' => 'submit']);
echo $this->Form->button('Cancel', ['type' => 'button', 'name'=>'cancel', 'onClick' => 'history.go(-1);return true;']);
echo $this->Form->end();
?>
</div>

用户控制器.php*

function add() {

            $user = $this->Users->newEntity();

            if ($this->request->is('post')) {
                    $user = $this->Users->patchEntity($user, $this->request->data);

                    if ($this->Users->save($user)) {
                            $this->Flash->set('The user has been saved');
                            return $this->redirect(array('action' => 'index'));
                    } else {
                            $this->Flash->set('The user could not be saved. Please, try again.');
                    }
            }
            $userTypes = $this->Users->UserTypes->find('list');
            $changeSteps = $this->Users->ChangeSteps->find('list');
            $environments = $this->Users->Environments->find('list');
            $this->set(compact('user','userTypes', 'changeSteps', 'environments'));
    }

第二个问题是，当我尝试送出表单以检查验证程式是否能正确行程空白的 name 字段时，我没有收到“您必须输入使用者的名称”消息，而是收到“这个字段是必要的”消息。为何它没有显示我来自notEmptyString的消息？“这个字段是必要的”是从哪里来的？

对于第一个问题，我必须在我的验证器中添加一个提供者。
我变了

$validator
   ->add('name', 'custom', array('rule' => 'checkExistingUser', 'message' => 'This user already appears to be in the system.', 'on' => 'create'));

到这

$validator
       ->add('name', 'custom', ['rule' => 'checkExistingUser', 'provider' => 'table', 'message' => 'This user already appears to be in the system.', 'on' => 'create']);

在打补丁的过程中，要小心使用自定义的验证方法，因为Cake期望返回字符串，否则它将呈现默认的消息。

// in a Controller
 $this->Users->patchEntity($user, $data, ['validate' => 'custom');

同样适用于密封件。

// in UserTable.php
 public function validationCustom(Validator $validator) {
        $validator = $this->validationDefault($validator);
        $validator           
        ->minLength('password',8,'At least 8 digits');
        $validator->add('password',  
            'strength_light',[
                'rule' => 'passwordCheck',
                'provider' => 'table',               
                'message' => 'At least a number and a capital letter'
            ]
            );
        return $validator;
    }
    public function passwordCheck ($value = "") {            
        return preg_match("/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}/",$value);
}

这将返回默认的消息而不是自定义的消息（“至少..”），因为我们设置了一个可调用的not-cakephp函数作为自定义验证的规则，所以消息应该由被调用的函数返回：

public function passwordCheck ($value = "") {            
     if (!preg_match("/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}/",$value))
         return "At least a number and a capital letter";

    }
