使用 Doctrine DataFixtures 时的 Symfony HttpFoundation UploadedFile "not uploaded due to unknown error"

Question

我一直在根据食谱使用我的附件实体 How To Handle File Uploads With Doctrine在 Symfony 2.3 中。

即使在功能测试中，它也运行良好。然而，将它与 Doctrine DataFixtures 一起使用会给我带来问题。

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

这没有帮助，但我确实运行了 php app/console doctrine:fixtures:load -v显示堆栈跟踪，似乎异常不是在持久方法上引发的，而是在 $manager->flush() 上引发的

Attachment::setFile()需要 UploadedFile 的实例所以我想知道是否有办法解决这个问题。

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

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

is_uploaded_file() 的条件返回false因为该文件已经在服务器上。

<?php

/**
 * Prepopulate the database with image attachments.
 */
final class AttachmentFixtures extends AbstractFixture implements OrderedFixtureInterface, ContainerAwareInterface
{
    private static $imageData = array(
        array(
            'name' => "O RLY?",
            'file' => "o-rly",
            'type' => "jpg",
        ),
        //...
    );

    {
        return $this->container->get('kernel')->getRootDir() . '/../src/Acme/DemoBundle/Resources/public/default/images';

    {

        foreach (self::$imageData as $image) {
            $imageFilename         = sprintf('%s.%s',      $image['file'], $image['type']);
            $copiedImageFilename   = sprintf('%s-copy.%s', $image['file'], $image['type']);

            $pathToImageFile = sprintf('%s/%s', $this->getPathToImages(), $imageFilename);

            try {
                $filesystem->copy($pathToImageFile, $pathToCopiedFile = sprintf('%s/%s', $this->getPathToUploads(), $copiedImageFilename));
                $filesystem->chmod($pathToCopiedFile, 0664);

                $this->container->get('logger')->err("An error occurred while copying the file or changing permissions.");
            }

            $imageFile = new UploadedFile(
                $pathToCopiedFile,                                              // The full temporary path to the file

                'image/' . 'jpg' === $image['type'] ? 'jpeg' : $image['type'],  // Mime type - The type of the file as would be provided by PHP

            $imageAttachment->setName($image['name']);
            $imageAttachment->setFile($imageFile);

            // Populate a reference array for later use
            $imageReferences['attachment-'.$image['file']] = $imageAttachment;

            $manager->persist($imageAttachment);
        }

        $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);
        }
    }
}

现在有更好的解决方案:

UploadedFile 的构造函数有一个 bool 值 $test 参数，该参数禁用使用 is_uploaded_file 进行检查。此参数已添加用于测试/夹具代码。

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

示例:

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