当我尝试上传与图像断言不匹配的错误文件时,会发生此错误。只接受图像。

的用户类型:
$builder
->add('firstName', 'text', array(
'required' => true
))
->add('lastName', 'text', array(
'required' => true
))
->add('email', 'email', array(
'required' => true
))
->add('job', 'text', array(
'required' => false
))
->add('file', 'file', array(
'label' => false,
'required' => false,
))
;
控制器:
public function updateMyAccountAction($id, Request $request)
{
$entityManager = $this->get('doctrine')->getManager();
$user = $this->get('doctrine')
->getRepository('TestBackBundle:User')
->find($id);
if (!$user) {
throw $this->createNotFoundException('Unable to find User entity.');
}
$editForm = $this->createForm(new UserType(), $user);
$editForm->handleRequest($request);
if ($editForm->isValid()) {
$user->upload();
$entityManager->persist($user);
$entityManager->flush();
$this->get('session')->getFlashBag()->add('success', 'Your profile has been updated');
return $this->redirect($this->generateUrl('my_account', array('id' => $id)));
} else {
$this->get('session')->getFlashBag()->add('error', 'Erreur');
return $this->redirect($this->generateUrl('my_account', array('id' => $id)));
}
}
当我尝试测试图像断言是否工作更新(例如pdf文件)时,会发生此错误。该文件未更新,因此很好。但我的控制器中的闪存包和重定向不起作用...如果我在控制器var_dump("test")
中的else中写"test"
,则显示错误,Symfony检测到表单是无效。
发生错误时,这是堆栈跟踪的一部分:
在 /home/user/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php 在第155行
152. $this->roles,
153. $this->attributes
154. )
155. );
}
/**
at serialize(array(object(User),true,array(object(Role)),array())) 在 /home/kevin/www/sf2/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php 在第155行
读它,我觉得使用roles属性来序列化它有一个问题,因为它是一个数组(我们必须将这个属性声明为一个实现UserInterface
的数组)
为什么会出现这种错误?
答案 0 :(得分:8)
我找到了解决方案:我必须实现Serializable
这样的界面:official doc
答案 1 :(得分:0)
DOZ单词的额外精度很少:
最好在图像(或文件,或@Vich \ Uploadable)实体中实现\Serializable
,而不是在用户实体上实现\Serializable
,因为您可能会中断登录这种情况。
如果您像我一样使用VichUploader,请不要在用户实体上添加\Serializable
并将其添加到@Vich\Uploadable
(图像或文件)实体以及这两种方法上:
/** @see \Serializable::serialize() */
public function serialize()
{
return serialize(array(
$this->id,
$this->image,
));
}
/** @see \Serializable::unserialize() */
public function unserialize($serialized)
{
list (
$this->id,
$this->image,
) = unserialize($serialized, array('allowed_classes' => false));
}
