我正在尝试对自定义验证器使用依赖注入,以便能够使用entityManager。
我按照Symfony示例:Dependency Injection,但我总是收到此错误消息:
FatalErrorException:错误:找不到类'isdoi' /home/milos/workspace/merrin3/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Validator/ConstraintValidatorFactory.php 第68行
以下是我的课程:
1。 IsDOI课程:
<?php
namespace Merrin\MainBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
/**
* @Annotation
*/
class IsDOI extends Constraint
{
public $message_publisher_DOI = 'The Publisher DOI abbreviation does not correspond to the DOI you filled in !';
public $message_journal_DOI = 'No journal found with the DOI you filled in !';
public $journal;
public $doiAbbreviation;
public function validatedBy() {
return "isdoi";
}
public function getTargets()
{
return self::CLASS_CONSTRAINT;
}
}
2。 IsDOIValidator类:
<?php
namespace Merrin\MainBundle\Validator\Constraints;
use Doctrine\ORM\EntityManager;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
class IsDOIValidator extends ConstraintValidator
{
private $entityManager;
public function __construct(EntityManager $entityManager)
{
$this->entityManager = $entityManager;
}
public function validate($value, Constraint $constraint)
{
$em_mdpipub = $this->entityManager('mdpipub');
//Do some tests here...
}
}
第3。服务:
merrin.main.validator.isdoi:
class: Merrin\MainBundle\Validator\Constraints\IsDOIValidator
arguments:
entityManager: "@doctrine.orm.entity_manager"
我哪里错了?谢谢你的帮助。
答案 0 :(得分:7)
您的服务文件错误,当您添加标签和别名时,您可以使用“isdoi”名称
merrin.main.validator.isdoi:
class: Merrin\MainBundle\Validator\Constraints\IsDOIValidator
arguments:
entityManager: "@doctrine.orm.entity_manager"
tags:
- { name: validator.constraint_validator, alias: isdoi }
答案 1 :(得分:3)
您告诉Symfony2您的约束的验证程序类是isdoi
(validateBy method
)。但是,您的验证工具为IsDOIValidator
。
您必须使用:
public function validateBy()
{
return "IsDOIValidator";
}
但是,如果您的Constraint
班级名称为IsDOI
,Symfony会自动将IsDOIValidator
视为ConstraintValidator
。 validateBy
的默认行为是将“Validator”附加到约束名称,并查找具有此名称的类。因此,如果您不重载validateBy
,Symfony2将自动搜索IsDOIValidator
。
