所以我得到了一个ZF2应用程序，在InputFilter中得到了一个Form和一个InputFilter：

$this->add(
        array(
            'name'       => 'email',
            'required'   => true,
            'validators' => array(
                array(
                    'name' => 'EmailAddress'
                ),
                array(
                    'name'      => 'DoctrineModule\Validator\NoObjectExists',
                    'options' => array(
                        'object_repository' => $sm->get('doctrine.entitymanager.orm_default')->getRepository('YrmUser\Entity\User'),
                        'fields'            => 'email'
                    ),
                ),
            ),
        )
    );

工作得很好，但是当我编辑现有对象并保存它时，NoObjectExists验证器说找到匹配的对象，因此它不会验证。 有这个问题的解决方案吗？ 或者我应该删除编辑表单上的验证器并在插入重复时捕获异常？

更新： How to use DoctrineModule\Validator\NoObjectExists in edit forms - Zend Framework 2 & Doctrine 2

是同样的问题，但答案是在编辑时删除验证器，这个过程不是解决方案。因为你仍然必须捕获插入副本时抛出的异常。我可以做到这一点没有问题，但我要求的是一个解决方案，使它与NoObjectExists一起使用（否则，如果我必须捕获重复项的异常，那么是否使用此验证器）

UPDATE，添加了其他相关代码（我的表单和实体有更多的字段，但我删除了它们以保持可读性）

FORM：

namespace YrmUser\Form;

use Zend\Form\Form;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator;
use DoctrineORMModule\Stdlib\Hydrator\DoctrineEntity;

use YrmUser\Entity\User;



class UserForm extends Form
{
protected $objectManager;

/**
 * __construct description
 *
 * @param String $name form name
 * 
 * @return void
 */
public function __construct($name = null)
{
    parent::__construct('new-user');
}

public function init()
{
    $this->setHydrator(
        new DoctrineHydrator($this->objectManager, 'YrmUser\Entity\User')
    )->setObject(new User());

    $this->setAttribute('method', 'post');


    $this->add(
        array(
            'name' => 'email',
            'attributes' => array(
                'type'  => 'email',
                'placeholder' =>'Email',
            ),
            'options' => array(
                'label' => 'Email',
            ),
        )
    );

}
}

FILTER：

class UserFilter extends InputFilter
{
/**
 * [__construct description]
 * 
 * @param ServiceLocator $sm servicelocator
 */
public function __construct($sm)
{


    $this->add(
        array(
            'name'       => 'email',
            'required'   => true,
            'validators' => array(
                array(
                    'name' => 'EmailAddress'
                ),
                array(
                    'name'      => 'DoctrineModule\Validator\NoObjectExists',
                    'options' => array(
                        'object_repository' => $sm->get('doctrine.entitymanager.orm_default')->getRepository('YrmUser\Entity\User'),
                        'fields'            => 'email'
                    ),
                ),
            ),
        )
    );
}
}

控制器行动：

public function editAction() 
{
    $id = (int) $this->params('id', null);
    if (null === $id) {
        return $this->redirect()->toRoute('manage-users');
    }

    $em = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');

    $formManager = $this->getServiceLocator()->get('FormElementManager');
    $form = $formManager->get('UserForm');

    $user = $em->find('YrmUser\Entity\User', $id);
    $form->setInputFilter(new UserFilter($this->getServiceLocator()));
    $form->bind($user);

    $request = $this->getRequest();
    if ($request->isPost()) {
        $form->setData($request->getPost());
        if ($form->isValid()) {
            $em->persist($user);
            $em->flush();
            return $this->redirect()->toRoute('manage-users');
        }
    }

    return array(
        'form' => $form,
        'id' => $id
    );
}

ENTITY：

class User
{
/**
 * @var int
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;



/**
 * @var string
 * @ORM\Column(type="string", unique=true,  length=255)
 */
protected $email;



/**
 * Get id.
 *
 * @return int
 */
public function getId()
{
    return $this->id;
}

/**
 * Set id.
 *
 * @param int $id user id
 *
 * @return void
 */
public function setId($id)
{
    $this->id = (int) $id;
}


/**
 * Get email.
 *
 * @return string
 */
public function getEmail()
{
    return $this->email;
}

/**
 * Set email.
 *
 * @param string $email user email adress
 *
 * @return void
 */
public function setEmail($email)
{
    $this->email = $email;
}
}

我最近在我的项目中遇到了同样的问题，我花了很多时间寻找解决方案，而且我终于找到了这个模块LosBase。

它使用两个海关验证器，其DoctrineModule\Validator\NoObjectExists NoEntityExists Add行动NoOtherEntityExists Edit use Zend\Validator\Exception\InvalidArgumentException; use DoctrineModule\Validator\NoObjectExists; class NoOtherEntityExists extends NoObjectExists { private $id; //id of the entity to edit private $id_getter; //getter of the id private $additionalFields = null; //other fields public function __construct(array $options) { parent::__construct($options); if (isset($options['additionalFields'])) { $this->additionalFields = $options['additionalFields']; } $this->id = $options['id']; $this->id_getter = $options['id_getter']; } public function isValid($value, $context = null) { if (null != $this->additionalFields && is_array($context)) { $value = (array) $value; foreach ($this->additionalFields as $field) { $value[] = $context[$field]; } } $value = $this->cleanSearchValue($value); $match = $this->objectRepository->findOneBy($value); if (is_object($match) && $match->{$this->id_getter}() != $this->id) { if (is_array($value)) { $str = ''; foreach ($value as $campo) { if ($str != '') { $str .= ', '; } $str .= $campo; } $value = $str; } $this->error(self::ERROR_OBJECT_FOUND, $value); return false; } return true; } } 行动。< / p>

所以我用这个appraoch来解决我的问题。这是我到目前为止所做的解决方案：

NoOtherEntityExists验证器： 

use Zend\Validator\Exception\InvalidArgumentException;
use DoctrineModule\Validator\NoObjectExists;

class NoEntityExists extends NoObjectExists
{
    private $additionalFields = null;
    public function __construct(array $options)
    {
        parent::__construct($options);
        if (isset($options['additionalFields'])) {
            $this->additionalFields = $options['additionalFields'];
        }
    }
    public function isValid($value, $context = null)
    {
        if (null != $this->additionalFields && is_array($context)) {
            $value = (array) $value;
            foreach ($this->additionalFields as $field) {
                $value[] = $context[$field];
            }
        }
        $value = $this->cleanSearchValue($value);
        $match = $this->objectRepository->findOneBy($value);
        if (is_object($match)) {
            if (is_array($value)) {
                $str = '';
                foreach ($value as $campo) {
                    if ($str != '') {
                        $str .= ', ';
                    }
                    $str .= $campo;
                }
                $value = $str;
            }
            $this->error(self::ERROR_OBJECT_FOUND, $value);
            return false;
        }
        return true;
    }
}

NoEntityExists验证器： 

input filters

将此验证器与inputFilter一起使用：

在我的自定义NoEntityExists中，我添加了两个方法：一个用于附加NoOtherEntityExists验证程序，另一个用于附加/** * Appends doctrine's NoObjectExists Validator for Add FORM . * * @param \Doctrine\ORM\EntityRepository $repository * @return \Zend\InputFilter\InputFilter */ public function appendAddValidator(EntityRepository $repository) { $this->add($this->getFactory()->createInput( array( 'name' => 'libellesite', //unique field name 'validators' => array( array( 'name' => 'Netman\Form\NoEntityExists',//use namespace 'options' => array( 'object_repository' => $repository, 'fields' => 'libellesite', 'messages' => array( 'objectFound' => 'custom message here' ), ), ), ) ))); return $this; } /** * Appends doctrine's NoObjectExists Validator for EDIT FORM. * * @param \Doctrine\ORM\EntityRepository $repository * @return \Zend\InputFilter\InputFilter */ public function appendEditValidator(EntityRepository $repository, $id) { $this->add($this->getFactory()->createInput( array( 'name' => 'libellesite', 'validators' => array( array( 'name' => 'Netman\Form\NoOtherEntityExists', 'options' => array( 'object_repository' => $repository, 'fields' => 'libellesite', 'id'=>$id, // 'id_getter'=>'getCodesite',//getter for ID 'messages' => array( 'objectFound' => 'custom message here' ), ), ), ) ))); return $this; } 验证程序：

addAction

控制器：

在$repository = $em->getRepository('Entity\Name'); $form->setInputFilter($filter->appendAddValidator($repository)); ：

editAction

在$id = $this->params('id', null); $repository = $em->getRepository('Entity\Name'); $form->setInputFilter($filter->appendEditValidator($repository,$id)); ：
