Cake PHP 2.x 模型验证被调用了两次

Question

当我尝试在我的模型中验证来自控制器的数据时，错误在 invalidFields 数组中出现两次，但我不明白为什么。

这是我的代码：

<?php
App::uses('AppController', 'Controller');
App::import('Vendor','Excel');

class ServicedesksController extends AppController{
    public $uses = array("CustomerInformation");

    public function uploadData(){
    $this->layout = 'index';

    if($this->request->is('post')){ 
        $safeData = array('name' => 'testkun', 'kkz' => 'bae');
        $this->CustomerInformation->set($safeData);
        if($this->CustomerInformation->validates()){
            print_r("successful");
        }else{
            print_r($this->CustomerInformation->invalidFields());
            print_r("not successful");
        }
    }

}

这是我的模型代码：

<?php

class CustomerInformation extends AppModel{
    public $validate = array(
        'name' => array(
             'rule' => array('minLength', '8'),
             'message' => 'Minimum length of 8 is required'
         ),
         'kkz' => array(
             'rule-1' => array(
                 'rule' => '/^[A-Z]{3}$/i',
                 'message' => 'Only letters allowed'
             ),
             'rule-2' => array(
                 'rule' => 'checkDuplicate',
                 'message' => 'There is still an existing entry for this kkz',
                 'last' => false

             )
         )
     );

     public function checkDuplicate($check){
        $existingCount = $this->find('count', array(
             'conditions' => $check
        ));
        return $existingCount == 0;

    }
}

当我执行uploadData时，invalidFields包含

Array ( 
    [name] => Array ( 
        [0] => Minimum length of 8 is required 
        [1] => Minimum length of 8 is required 
)

为什么我两次收到这个错误？我已经尝试重命名字段，减少验证规则并使用不同的模型和 Controllers/Consoles 进行测试。但是所有人都有相同的行为。

我找不到任何关于此的错误报告。如果有人能帮助我，我会很高兴。

来自食谱：

The validates method invokes the invalidFields method which populates the validationErrors property of the model. The invalidFields method also returns that data as the result:

$errors = $this->ModelName->invalidFields(); // contains validationErrors array

The validation errors list is not cleared between successive calls to invalidFields(). So if you are validating in a loop and want each set of errors separately don’t use invalidFields(). Instead use validates() and access the validationErrors model property.

因此，您应该调用：

print_r($this->CustomerInformation->validationErrors);

而不是

print_r($this->CustomerInformation->invalidFields());
