最近几天尝试了，作为Symfony的新手找到了一个很好的解决方案，可以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指南，但不幸的是我无法理解。
标题
中指定的设置Symfony2的 SonataAdmin 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，我在提交后收到错误。
这是第75行：
/**

* 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

*/
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use课程的File声明：use Symfony\Component\HttpFoundation\File\File;
答案 1 :(得分：0)
添加上面的use语句，然后将方法签名更改为：
public function setImageFile(File $image = null)
