Question

我在Sonata Admin

中添加自定义操作时出现以下错误

FatalErrorException：错误：在/myproject_path/AppBundle/Admin/BalticsAdmin.php第106行中找不到类'Symfony \ Component \ Debug \ Exception \ FlattenException'

这是什么问题请与我分享

这是代码

在管理类

中

protected function configureListFields(ListMapper $listMapper)
{
    $listMapper
        ................................
        .................
        ->add('_action', 'actions', array(
            'actions' => array(
                'show' => array(),
                'edit' => array(),
                'delete' => array(),
                'upload' => array('template' => 'SteelGuruBundle:CRUD:list__action_upload.html.twig'),
            )
        ));
}

protected function configureRoutes(RouteCollection $collection)
{
    $collection->add('upload', $this->getRouterIdParameter().'/upload');
}

然后我在src /.../.../ Controller / CRUDController.php中使用以下代码创建一个控制器类

namespace ...\AppBundle\Controller;

use Sonata\AdminBundle\Controller\CRUDController as Controller;

class CRUDController extends Controller
{
public function uploadAction()
{
    $id = $this->get('request')->get($this->admin->getIdParameter());

    $object = $this->admin->getObject($id);

    if (!$object) {
        throw new NotFoundHttpException(sprintf('unable to find the object with id : %s', $id));
    }

}
}

然后我在src /.../ AppBundle / Resources / views / CRUD / list__action_upload.html.twig中使用以下代码创建模板

<a class="btn btn-small" href="{{ admin.generateObjectUrl('upload', object) }}">Upload</a>

然后在services.yml中添加了以下内容

sg_app.admin.baltic:
    class: ...\AppBundle\Admin\BalticsAdmin
    tags:
        - { name: sonata.admin, manager_type: orm, audit:false, group: Test, label: Upload}
    arguments: [null, ...\AppBundle\Entity\Baltics, ...AppBundle:CRUD]

感谢您的回复

我有类似的问题，发现我必须添加

use Sonata\AdminBundle\Route\RouteCollection;

指向管理员（在您的案例中为BalticAdmin）。

我得到了FatalErrorException：试图在sonata admin中创建自定义动作
