使用Doctrine DataFixtures时，Symfony HttpFoundation UploadedFile“由于未知错误而未上传”

Question

我一直在使用基于食谱食谱如何使用 Symfony 2.3中的Doctrine处理文件上传的附件实体。

即使在功能测试中，它也可以正常工作。但是，将它与Doctrine DataFixtures一起使用会引起我一些问题。

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

这没有帮助，但是我确实运行php app/console doctrine:fixtures:load -v了堆栈跟踪，并且似乎不是在持久化方法上抛出了异常，而是在$manager->flush()

Attachment::setFile()需要一个实例，UploadedFile所以我想知道是否有解决方法。

看来错误发生在225行 Symfony\Component\HttpFoundation\File\UploadedFile

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

is_uploaded_file()返回的条件，false因为文件已在服务器上。

        $manager->flush(); // <-- Exception throw here


        // Create references for each image to be used by other entities that
        // maintain a relationship with that image.
        foreach ($imageReferences as $referenceName => $image) {
            $this->addReference($referenceName, $image);
        }
    }

Answer 1

现在有一个更好的解决方案：

的构造函数UploadedFile具有boolean $test参数，可使用禁用检查is_uploaded_file。此参数已添加用于测试/灯具代码。

只需将其设置为true，对的isValid()检查UploadedFile将不再是问题。

例：

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

感谢 stof ，解决方案是为的父类的实例创建Attachment::setFile()（或者Document::setFile()如果使用说明书示例）提示，并在fixtures类中创建一个新实例并将其传递给 setFile 方法UploadedFileSymfony\Component\HttpFoundation\File\File

附件.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';
        }
    }

    //...
}

附件Fixtures.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);
        //...
    }
}
