Symfony 2 BlueImp OneupUploaderBundle sql错误PostPersistEvent不

Question

我正在尝试构建一个Eventlistener，以便在创建实体时将图像的路径（url）持久化到数据库。我使用的是Blueimp（jQuery File Uploader）。但是我得到了一个sql异常。我猜有些东西和我的听众没有联系。

An exception occurred while executing 'INSERT INTO Image (name, url) VALUES (?, ?)' with params ["dasdasdas", null]

我的配置yml

oneup_uploader:
mappings:
    gallery:
        frontend: blueimp

我的服务.yml

services:
app.bundle.upload_listener:
    class: AppBundleEventlistenerImageuploadListener
    arguments: ["doctrine.orm.entity_manager"]
    tags:
        -  { name: kernel.event_listener,  event: oneup_uploader.post_persist, mehtod: onPostUpload}

我的图像实体

namespace AppBundleEntity;
use DoctrineORMMapping as ORM;    
/**
 * Image
 *
 * @ORMTable()
 * @ORMEntity
 */
class Image
{
/**
 * @var integer
 *
 * @ORMColumn(name="id", type="integer")
 * @ORMId
 * @ORMGeneratedValue(strategy="AUTO")
 */
private $id;
/**
 * @var string
 *
 * @ORMColumn(name="name", type="string", length=255)
 */
private $name;
/**
 * @var string
 *
 * @ORMColumn(name="url", type="string", length=255)
 */
private $url;

/**
 * Get id
 *
 * @return integer 
 */
public function getId()
{
    return $this->id;
}
/**
 * Set name
 *
 * @param string $name
 * @return Image
 */
public function setName($name)
{
    $this->name = $name;
    return $this;
}
/**
 * Get name
 *
 * @return string 
 */
public function getName()
{
    return $this->name;
}
/**
 * Set url
 *
 * @param string $url
 * @return Image
 */
public function setUrl($url)
{
    $this->url = $url;
    return $this;
}
/**
 * Get url
 *
 * @return string 
 */
public function getUrl()
{
    return $this->url;
}
}

我的imageuploadListener

namespace AppBundleEventlistener;
use AppBundleEntityImage;
use OneupUploaderBundleEventPostPersistEvent;
class ImageuploadListener
{
protected $manager;
public function __construct(DoctrineORMEntityManager $manager)
{
 $this->manager = $manager;
}
public function onPostUpload(PostPersistEvent $event)
{   
    $file = $event->getFile();
    $object = new Image();
    $object->setUrl($file->getPathName());
    $this->manager->persist($object);
    $this->manager->flush();
}
}

我收到一个jquery 500错误，但图像被移到了一个文件夹中。权限正常（所有访问）。

POST http://localhost:8000/_uploader/gallery/upload 500 (Internal Server Error)

编辑：我在错误日志中发现了这个：

 [2015-04-03 11:23:23] event.INFO: An exception was thrown while getting the uncalled listeners (Catchable Fatal Error: Argument 1 passed to AppBundleEventlistenerImageuploadListener::__construct() must be an instance of AppBundleEventlistenerEntityManager, array given, called in D:x...appcachedevappDevDebugProjectContainer.php on line 359 and defined) {"exception":"[object] (Symfony\Component\Debug\Exception\ContextErrorException(code: 0): Catchable Fatal Error: Argument 1 passed to AppBundle\Eventlistener\ImageuploadListener::__construct() must be an instance of AppBundle\Eventlistener\EntityManager, array given, called in D:\....\app\cache\dev\appDevDebugProjectContainer.php on line 359 and defined at D:\...\src\AppBundle\Eventlistener\ImageuploadListener.php:12)"} []

第2版：我已经将EntityManager更改为\Doctrine\ORM\EntityManager，现在我收到了一个不同的错误（dev.log）：

 request.CRITICAL: Uncaught PHP Exception SymfonyComponentDebugExceptionContextErrorException: "Warning: call_user_func() expects parameter 1 to be a valid callback, class 'AppBundleEventlistenerImageuploadListener' does not have a method 'onOneupuploaderPostpersist'" at D:...vendorsymfonysymfonysrcSymfonyComponentEventDispatcherDebugWrappedListener.php line 61

知道为什么吗？能请谁向我解释一下我做错了什么吗？哪个文件正在OneupuploaderPostpersistent上调用此方法？

Answer 1

在文件service.yml中

mehtod: onPostUpload

是打字错误，而不是"mehtod"，你应该有"方法"

该方法可能是OneupUploaderBundle在侦听器上调用的默认方法，如果未另行指定
