我在原型和图像之间有一对多的关系，一个原型可以有很多图像。 我试过用vich，这就是我所拥有的： 我可以上传图片但不能同时上传。我必须编辑，保存然后上传第二个。 此外，我希望能够在每个部分上传多个图像：桌面，平板电脑和移动设备。 以下是My PrototypeAdmin的代码：
<?php
namespace AppBundle\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Show\ShowMapper;
class ImageAdmin extends Admin
{
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('commentaire','text',array('label'=>'Commentaire'))
->add('typeDevice', 'text', array('label' => 'Type de device'))
->add('image', 'file', array('required' => false , 'label' => 'image'))
->add('prototype','entity',array('class' => 'AppBundle\Entity\Prototype'))
;
}
protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
}
protected function configureListFields(ListMapper $listMapper)
{
}
}
首先，我可以在“桌面”部分上传，但不能在“Tablette”和“移动”中上传。
然后这是我的ImageAdmin：

和Image.php
php app/console sonata:easy-extends:generate --dest=src SonataMediaBundle
我刚刚开始使用Symfony和Sonata而且还有另外一种方法可以做到这一点。
修改
我刚检查了mediaBundle，我正在按照文档中的步骤进行操作。我是否需要使用此命令生成实体
{{1}}
或许我可以在自己的实体中进行更改？
答案 0 :(得分：0)
您的问题似乎与VichUploaderBundle没有直接关系，您可能只需要为images字段添加两个选项：allow_add和allow_delete（两者都设置）到true）。您可能还想将by_reference设置为false。
我在my sandbox中实现了您想要实现的目标。
