因此,我致力於Sonata Admin自定義應用程序。我試圖創建一個自定義操作來下載擴展CRUDController的控制器中的文件。Sonata Admin使用註釋捆綁自定義路線
的操作是:
/**
* @Route("/download-list/{id}", name="download_list")
*/
public function downloadListAction($id = null) {
$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));
}
if (false === $this->admin->isGranted('VIEW', $object)) {
throw new AccessDeniedException();
}
$entity = $this->admin->getSubject();
$exportFolder = $this->container->getParameter('export_folder');
$filePath = $this->get('kernel')->getRootDir() . $exportFolder . DIRECTORY_SEPARATOR . $entity->createListFileName() . $this->extension;
$response = new BinaryFileResponse($filePath);
$response->headers->set('Content-Type', 'text/plain');
return $response->setContentDisposition(ResponseHeaderBag::DISPOSITION_ATTACHMENT, $entity->createListFileName());
}
在routing.yml
我有
spam_list_admin:
resource: "@SpamAdminCoreBundle/Controller/SpamListAdminController.php"
type: annotation
prefix: /list
路由器調試器顯示我的路線,我可以使用$this->get('router')->generate('download_list', array('id' => $id))
的URI,但如果我訪問它(app_dev.php/list/download-list/6)我得到
There is no `_sonata_admin` defined for the controller `SpamAdmin\CoreBundle\Controller\SpamListAdminController` and the current route `download_list`.
此消息很明顯唉廢話,這裏真正的交易是什麼?
謝謝。在此期間,我注意到我需要配置路徑「for symfony」,以便能夠使用「$ this-> get('router') - > generate」創建uri並且還能夠訪問「Sonata」這一頁。 –
