作为 Symfony 的新手，花了最后几天的时间尝试找到一个很好的解决方案，将图像上传字段集成到 Sonata Admin 中的现有实体中。我一直在谷歌搜索并遵循可用的指南，但不幸的是我无法弄清楚。

标题中指定的设置

Symfony2 奏鸣曲管理员 VichUploaderBundle

我目前遇到以下错误:

"Catchable Fatal Error: Argument 1 passed to Beautify\BeautiesBundle\Entity\Beauty::setImageFile() must be an instance of Symfony\Component\HttpFoundation\File\UploadedFile, instance of Symfony\Component\HttpFoundation\File\File given, called in /Users/gmf/symfony/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 438 and defined in /Users/gmf/symfony/src/Beautify/BeautiesBundle/Entity/Beauty.php line 75 "

图片上传字段正确呈现，提交后收到错误。

这是第 75 行:

/**
* If manually uploading a file (i.e. not using Symfony Form) ensure an instance
* of 'UploadedFile' is injected into this setter to trigger the  update. If this
* bundle's configuration parameter 'inject_on_load' is set to 'true' this setter
* must be able to accept an instance of 'File' as the bundle will inject one here
* during Doctrine hydration.
*
* @param File|\Symfony\Component\HttpFoundation\File\UploadedFile
*/
public function setImageFile(UploadedFile $image = null)
{
    $this->imageFile = $image;

    if ($image) {
        // It is required that at least one field changes if you are using doctrine
        // otherwise the event listeners won't be called and the file is lost
        $this->updatedAt = new \DateTime('now');
    }
}

您错过了 File 类的 use 语句:use Symfony\Component\HttpFoundation\File\File;
