我停下来此错误：
开捕致命错误：传递给小丑\ CoreBundle \实体\ Incidentfile :: setFile（参数1）必须的Symfony \分量\ HttpFoundation \文件\ UploadedFile的，给定的字符串，堪称/应用程序/ MAMP / htdocs中/百搭回购的实例/vendor/symfony/symfony/src/Symfony/Component/Form/Util/PropertyPath.php上线538和在/Applications/MAMP/htdocs/joker-repo/src/Joker/CoreBundle/Entity/Incidentfile.php线157限定
在我的实体我有文件getter和setter方法。 我用这个方法来使文件上传： THIS
并有对文件夹的权限upload_images问题，但后，我解决它一切正常，但现在出现了一些问题。
下面是实体

这里是我的CONTROLER：
public function TestAction(Request $request){
$incfileRepo = new Incidentfile();
$formfile = $this->createForm(new IncfileType(), $incfileRepo);
if ($request->isMethod('POST')) {
$formfile->bind($request);
if ($formfile->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($incfileRepo);
$em->flush();
return $this->redirect($this->generateUrl('incident_show'));
}
}
$spotEntity = $this->getCurrentSpot();
$sentryEntity = $this->getCurrentSentry();
$messagesCollection = $this->getDoctrine()->getRepository('JokerCoreBundle:Message')->findBy(array(
'spot' => $spotEntity,
'sentry' => $sentryEntity
), array(
'sent_date' => 'DESC'
));
return $this->render('JokerAdminBundle:incidents:addfullform.html.twig', $this->getViewConstants(array(
'formfile'=>$formfile->createView(),
'spot' => $spotEntity,
'sentry' => $sentryEntity,
'messagesCollection' => $messagesCollection,
)));
}
形成树枝：
<form action="" method="post">
{{ form_rest(formfile) }}
<div class="singleTableForm">
<input style="float: left; margin-left: 338px; " type="submit" name="" class="button" value="Add" />
</div>
</form>
