Как загрузить в Blog Entity в SonataAdminBundle?

Question

Я новичок Symfony, и я пытаюсь загрузить в IMG SonataAdminBundle.I Folow эту документацию: http://sonata-project.org/bundles/admin/master/doc/cookbook/recipe_file_uploads.html Но я получил ошибку:

Catchable Fatal Error: Argument 1 passed to MyBlogBundle\Entity\Blog::setFile() must be an instance of MyBlogBundle\Entity\UploadedFile, instance of Symfony\Component\HttpFoundation\File\UploadedFile given, called in C:\OpenServer\domains\Symfony.test\vendor\symfony\symfony\src\Symfony\Component\PropertyAccess\PropertyAccessor.php on line 442 and defined

Может кто-нибудь помочь мне с этим?

Answer 1

Вы забыли добавить использовать заявление для класса UploadedFile , вы должны добавить:

SRC/MyBLogBundle/Entity/blog.php

<?php 
use Symfony\Component\HttpFoundation\File\UploadedFile; 

class Blog 
{ 
} 

Вы должны указать где находится UploadedFile, если это не в пространстве имен по умолчанию файла (в настоящее время: SRC/MyBLogBundle/Entity)
