Symfony2 FOSUserBundle用户图片上传

Question

我正在尝试使用FOSUserBundle将配置文件图片添加到我的用户实体的symfony2项目中。我已经与symfony2文件上传过程合作，当我使用FOSUserBundle时，我只有上传和数据库存在问题。

这里是我的实体：

namespace ICGM2\UserBundle\Entity; 

use FOS\UserBundle\Entity\User as BaseUser; 
use Doctrine\ORM\Mapping as ORM; 
use Doctrine\Common\Collections\ArrayCollection; 
use Symfony\Component\Validator\Constraints as Assert; 
use Symfony\Component\HttpFoundation\File\UploadedFile; 

/** 
* @ORM\Entity 
* @ORM\Table(name="user") 
*/ 
class User extends BaseUser 
{ 

/** 
* @ORM\Id 
* @ORM\Column(type="integer") 
* @ORM\GeneratedValue(strategy="AUTO") 
*/ 
protected $id; 
/** 
* @ORM\Column(type="string", length=255, nullable=true) 
*/ 
public $path; 

/** 
* @Assert\File(maxSize="6000000") 
*/ 
public $file; 

/*  * *************************************************************** */ 

/** 
* @ORM\PrePersist() 
* @ORM\PreUpdate() 
*/ 
public function preUpload() 
{ 
    if (null !== $this->file) { 
     $this->path = uniqid('', true) . '.' . $this->file->guessExtension(); 
    } 
} 

/** 
* @ORM\PostPersist() 
* @ORM\PostUpdate() 
*/ 
public function upload() 
{ 
    if (null === $this->file) { 
     return; 
    } 
    $this->file->move($this->getUploadRootDir(), $this->path); 
    unset($this->file); 
} 

/** 
* @ORM\PostRemove() 
*/ 
public function removeUpload() 
{ 
    if ($file == $this->getAbsolutePath()) { 
     unlink($file); 
    } 
} 

public function getAbsolutePath() 
{ 
    return null === $this->path ? null : $this->getUploadRootDir() . '/' . $this->path; 
} 

public function getWebPath() 
{ 
    return null === $this->path ? null : $this->getUploadDir() . '/' . 
      $this->id . '/' . $this->path; 
} 

protected function getUploadRootDir() 
{ 
    return __DIR__ . '/../../../../web/' . $this->getUploadDir() . '/' . $this->id; 
} 

protected function getUploadDir() 
{ 
    return 'uploads/users'; 
} 

    /** 
* Set path 
* 
* @param string $path 
* @return User 
*/ 
public function setPath($path) 
{ 
    $this->path = $path; 

    return $this; 
} 

/** 
* Get path 
* 
* @return string 
*/ 
public function getPath() 
{ 
    return $this->path; 
} 

....

和表单：UserType.php

$builder->add('file', 'file', array(
     'required' => false 
    ));

嗨如果有人在这里度过了同样的问题，他的解决方案。我改变了用户实体的一些功能：

/** 
* @param UploadedFile $file 
* @return object 
*/ 
public function setFile(UploadedFile $file = null) 
{ 
    // set the value of the holder 
    $this->file = $file; 
    // check if we have an old image path 
    if (isset($this->path)) { 
     // store the old name to delete after the update 
     $this->t = $this->profilePicturePath; 
     $this->tempPath = null; 
    } else { 
     $this->path = 'initial'; 
    } 

    return $this; 
} 

/** 
* Get the file used for profile picture uploads 
* 
* @return UploadedFile 
*/ 
public function getFile() 
{ 

    return $this->file; 
} 

/** 
* @ORM\PrePersist() 
* @ORM\PreUpdate() 
*/ 
public function preUpload() 
{ 
    if (null !== $this->getFile()) { 
     // a file was uploaded 
     // generate a unique filename 
     $filename = $this->generateRandomProfilePictureFilename(); 
     $this->setPath($filename . '.' . $this->getFile()->guessExtension()); 
    } 
} 

/** 
* Generates a 32 char long random filename 
* 
* @return string 
*/ 
public function generateRandomProfilePictureFilename() 
{ 
    $count = 0; 
    do { 
     $generator = new SecureRandom(); 
     $random = $generator->nextBytes(16); 
     $randomString = bin2hex($random); 
     $count++; 
    } while (file_exists($this->getUploadRootDir() . '/' . $randomString . '.' . $this->getFile()->guessExtension()) && $count < 50); 

    return $randomString; 
} 

/** 
* @ORM\PostPersist() 
* @ORM\PostUpdate() 
*/ 
public function upload() 
{ 
    if (null === $this->file) { 
     return; 
    } 
    $this->getFile()->move($this->getUploadRootDir(), $this->getPath()); 

    if (isset($this->tempPath) && file_exists($this->getUploadRootDir() . '/' . $this->tempPath)) { 
     unlink($this->getUploadRootDir() . '/' . $this->tempPath); 
     $this->tempPath = null; 
    } 
    $this->file = null; 
}
