在ZF3應用程序中使用DoctrineModule UniqueObject驗證程序註釋？

Question

我想在Zend\Form（ZF3）的實體中使用DoctrineModule的UniqueObject驗證程序註釋，但我無法這樣做。

詮釋實體：

* @Annotation\Validator({"name":"DoctrineModule\Validator\UniqueObject"}) 

使用實體

控制器方法：

public function saveAction() 
{ 
    $id = (int) $this->params()->fromRoute('id', 0); 
    $user = $this->em->getRepository(User::class)->find($id);   
    $builder = new AnnotationBuilder(); 
    ... 

Module.php：見於

public function getServiceConfig() 
{ 
    return [ 
     'factories' => [ 
      'DoctrineModule\Validator\UniqueObject' => function ($serviceManager) { 
       $uniqueObject = new DoctrineModule\Validator\UniqueObject(array(
        'fields' => 'username', 
        'object_repository' => $serviceManager->get('Doctrine\ORM\EntityManager')->getRepository('Application\Entity\User'), 
        'object_manager' => $serviceManager->get('Doctrine\ORM\EntityManager'), 
       )); 
       return $uniqueObject; 
      }, 
     ], 
    ]; 
} 

錯誤：

基於在線程DoctrineModule /問題/ 585的討論

，我注入了FormElementManager到通過工廠UserController的構造和連接它從那裏到AnnotationBuilder：

public function __construct(EntityManager $em, \Zend\Form\FormElementManager $fem) 
{ 
    $this->em = $em; 
    $this->fem = $fem; 
    ... 
} 


public function saveAction() { 
    ... 
    $builder->setFormFactory(new \Zend\Form\Factory($this->fem)); 
    ... 
} 

然而這只是最終回原始錯誤/堆棧跟蹤。有趣的是，當我轉儲$this->fem時，我在轉儲輸出中看到了UniqueObject驗證器，因此不清楚發生了什麼問題。我會很感激任何幫助或建議，以獲得由AnnotationBuilder承認的UniqueObject註釋。

一些鏈接我提到研究這個時候：

可以嘗試：

<?php 
/** 
* Zend Framework Application. 
*/ 

namespace Fork\DoctrineModule\Validator\Factory; 

use DoctrineModule\Validator\UniqueObject; 

use Interop\Container\ContainerInterface; 
use Zend\ServiceManager\Factory\FactoryInterface; 

/** 
* UniqueObjectFactory factory. 
* 
* Creates an instance of UniqueObject. 
* 
* @package Blog\Repository\Factory 
* @link https://github.com/doctrine/DoctrineModule/blob/master/docs/validator.md 
* @link https://github.com/doctrine/DoctrineModule/blob/master/src/DoctrineModule/Validator/UniqueObject.php 
*/ 
class UniqueObjectFactory implements FactoryInterface 
{ 

    /** 
    * Factory for UniqueObject. 
    * 
    * @param ContainerInterface $container 
    * @param string $requestedName 
    * @param array $options 
    * @return UniqueObject 
    */ 
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null) 
    { 
     // Get services. 
     $entityManager = $container->get('Doctrine\ORM\EntityManager'); 

     // If 'object_repository' string, try find repository in EntityManager. 
     // Sets ObjectManager. 
     if (is_string($options['object_repository'])) { 
      $options['object_manager'] = $entityManager; 
      $options['object_repository'] = $entityManager->getRepository($options['object_repository']); 
     } 

     return new UniqueObject($options); 
    } 

} 

，並在模塊

<?php 
/** 
* Zend Framework Application. 
*/ 

namespace Fork\DoctrineModule; 

/** 
* Configuration for Fork\DoctrineModule module. 
* 
* Changes and extends configuration of DoctrineModule module. 
* 
* @link https://github.com/doctrine/DoctrineModule/blob/master/config/module.config.php 
* @link https://github.com/doctrine/DoctrineModule/blob/master/src/DoctrineModule/Module.php 
*/ 
return [ 
    /** 
    * Configurations for Zend Framework services and components. 
    */ 
    'validators' => [ 
     'factories' => [ 
      Validator\UniqueObject::class => Validator\Factory\UniqueObjectFactory::class, 
     ], 
     'aliases' => [ 
      'UniqueObject' => Validator\UniqueObject::class, 
     ], 
    ], 
]; 

和註釋

* @Annotation\Validator({ 
* 'name': 'UniqueObject', 
* 'break_chain_on_failure': 'true', 
* 'options': { 
*  'object_repository': 'Application\Entity\User', // you have User::class 
*  'fields': {'bla-bla-bla'},   // ??? - what you have? 
*  'messages': { 
*   'objectFound' => "bla-bla-bla" 
*  }, 
* }, 
* })
