But when I select more than one file, I get this exception: <pre><code> The file "" does not exist 500 Internal Server Error - FileNotFoundException Stack Trace in /var/www/thegabrielhotel/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/File/MimeType/MimeTypeGuesser.php at line 115 - public function guess($path) { if (!is_file($path)) { throw new FileNotFoundException($path); } if (!is_readable($path)) { at MimeTypeGuesser ->guess ('') in /var/www/thegabrielhotel/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/File/File.php at line 87 + at File ->getMimeType () in /var/www/thegabrielhotel/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/File/File.php at line 64 + at File ->guessExtension () in /var/www/thegabrielhotel/src/Gbr/BEBundle/Document/OverviewPhoto.php at line 71 + at OverviewPhoto ->preUpload () in /var/www/thegabrielhotel/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/Mapping/ClassMetadataInfo.php at line 525 + at ClassMetadataInfo ->invokeLifecycleCallbacks ('prePersist', object(OverviewPhoto)) in /var/www/thegabrielhotel/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/UnitOfWork.php at line 953 + at UnitOfWork ->persistNew (object(ClassMetadata), object(OverviewPhoto)) in /var/www/thegabrielhotel/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/UnitOfWork.php at line 1775 + at UnitOfWork ->doPersist (object(OverviewPhoto), array('000000001f48b19e00007fd7abcd7e2a' => object(OverviewPhoto))) in /var/www/thegabrielhotel/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/UnitOfWork.php at line 1739 + at UnitOfWork ->persist (object(OverviewPhoto)) in /var/www/thegabrielhotel/vendor/doctrine/mongodb-odm/lib/Doctrine/ODM/MongoDB/DocumentManager.php at line 384 + at DocumentManager ->persist (object(OverviewPhoto)) in /var/www/thegabrielhotel/src/Gbr/BEBundle/Controller/DefaultController.php at line 57 + at DefaultController ->postOverviewPhotosAction (object(Request)) at call_user_func_array (array(object(DefaultController), 'postOverviewPhotosAction'), array(object(Request))) in kernel.root_dir/bootstrap.php.cache at line 2843 + at HttpKernel ->handleRaw (object(Request), '1') in kernel.root_dir/bootstrap.php.cache at line 2817 + at HttpKernel ->handle (object(Request), '1', true) in kernel.root_dir/bootstrap.php.cache at line 2946 + at ContainerAwareHttpKernel ->handle (object(Request), '1', true) in kernel.root_dir/bootstrap.php.cache at line 2248 + at Kernel ->handle (object(Request)) in /var/www/thegabrielhotel/web/app_dev.php at line 28 + </code></pre> Here's my layout part of dropzone: <pre><code><form action="{{ path("gbr_be_post_overview_photos") }}" class="dropzone" id="my-dropzone"> </form> </code></pre> And here's my <code>postOverviewPhotosAction</code> post action: <pre><code>public function postOverviewPhotosAction(Request $request) { $dm = $this->get("doctrine_mongodb")->getManager(); $files = $request->files; foreach($files as $file) { $overview_photo = new OverviewPhoto(); $overview_photo->setPhotoFile($file); $dm->persist($overview_photo); } $dm->flush(); return $this->render($this->generateUrl("gbr_be_get_overview")); } </code></pre> And <code>OverviewPhoto</code> document: <pre><code><?php namespace Gbr\BEBundle\Document; use Symfony\Component\Validator\Constraints as Assert; use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB; /** * @MongoDB\Document(collection="overview_photos", repositoryClass="Gbr\BEBundle\Repository\OverviewPhotoRepository") */ class OverviewPhoto { /** * @MongoDB\Id(strategy="AUTO") */ protected $id; /** * @MongoDB\Date */ protected $updated_at; /** * @Assert\Image */ protected $photo_file; /** * @MongoDB\String */ protected $photo_name; public function getUploadDir() { return 'uploads/images/overview/slider'; } public function getRootUploadDir() { return "/../../../../web/". $this->getUploadDir(); } public function getWebPath() { return $this->photo_name === null ? null : "/".$this->getUploadDir()."/".$this->photo_name; } public function getAbsolutePath() { return $this->photo_name === null ? null : "/".$this->getRootUploadDir()."/".$this->photo_name; } /** * WARNING!!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
