Symfony HttpFoundation UploadedFile“未上传，因为未知错误”使用Doctrine DataFixtures

Question

我一直在使用基于Symfony 2.3中的食谱收件人How To Handle File Uploads With Doctrine的附件实体。

它运作良好，即使在功能测试。但是在Doctrine DataFixtures中使用它会导致我遇到问题。

[Symfony\Component\HttpFoundation\File\Exception\FileException]
The file "o-rly-copy.jpg" was not uploaded due to an unknown error.

这是没有帮助的，但是我没跑php app/console doctrine:fixtures:load -v，弹出一个堆栈跟踪，并将其显示在没有抛出异常的持续性的方法，但在$manager->flush()

Attachment::setFile()需要一个UploadedFile的实例，所以我想知道是否有方法。

它出现在错误发生时对Symfony\Component\HttpFoundation\File\UploadedFile

return $this->test ? $isOk : $isOk && is_uploaded_file($this->getPathname()) 

条件225线is_uploaded_file()回报false因为该文件已经在服务器上。

Thanks to stof，解决的办法是使Attachment::setFile()（或Document::setFile()如果使用食谱例如）暗示为UploadedFile的父类，Symfony\Component\HttpFoundation\File\File的一个实例，并且在夹具类，创建一个新实例，并将其传递到setFile方法

Attachment.php

<?php 

namespace Acme\DemoBundle\Entity; 

use Symfony\Component\HttpFoundation\File\File; 
//... 

class Attachment 
{ 
    /** 
    * Sets file. 
    * 
    * @param File $file 
    */ 
    public function setFile(File $file = null) 
    { 
     $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->temp = $this->path; 
      $this->path = null; 
     } else { 
      $this->path = 'initial'; 
     } 
    } 

    //... 
} 

AttachmentF ixtures.php

<?php 

namespace Acme\DemoBundle\DataFixtures\ORM; 

use Symfony\Component\HttpFoundation\File\File; 
//... 

class AttachmentFixtures //... 
{ 
    //... 

    public function load(ObjectManager $manager) 
    { 
     //... 
     $imageFile = new File($pathToCopiedFile); 

     $imageAttachment = new Attachment(); 

     $imageAttachment->setFile($imageFile); 
     //... 
    } 
}

现在有一个更好的解决方案：

的UploadedFile构造函数有一个布尔$test参数，禁用使用is_uploaded_file检查。该参数已添加用于测试/夹具代码。

只需将其设置为true，检查UploadedFile将不再是一个问题了。

实施例：

// My data fixture code. 
$test = true; 
$userPhoto->setImageFile(new UploadedFile($photoDir . $photoFile, $photoFile, null, null, null, $test));
