问题描述
我正在尝试通过我的用户实体上的 vichuploader bundle 上传文件.使用实现 UserInterface 的 hwioauthbundle，我认为错误来自那个包......因此，每次我尝试上传文件时，都会遇到此异常:
I'm trying to upload a file via vichuploader bundle on my Users entity. Using hwioauthbundle that implements UserInterface, and i think the errors comes from that bundle... So every time i try to uplod a file i got this exception :
'Symfony\Component\HttpFoundation\File\UploadedFile'的序列化不允许
Serialization of 'Symfony\Component\HttpFoundation\File\UploadedFile' is not allowed
我已经尝试过 这个解决方案但也是同样的例外.
I already tried this solution but also same exception.

我的表单用户类型:
use AppBundle\Form\FilesType;
->add('cv',FilesType::class)
我的表单文件类型:
-> add('imageFile',
VichFileType::class, [
'required' => false,
'allow_delete' => true,
'download_link' => true,
'label' => false,
]);
推荐答案
您正在此代码中序列化 ImageFile 实体，这就是您收到错误的原因，请尝试删除它并添加 updatedAt 字段，以便学说可以跟踪实体的变化:
You are serializing ImageFile entity within this code that's why you are getting the error , try removing that and add updatedAt field so that doctrine can track changes on the entity:
/**
* Files
* @ORM\Table(name="files")
* @ORM\Entity(repositoryClass="AppBundle\Repository\FilesRepository")
* @Vich\Uploadable
*/
class Files implements \Serializable
{
