我有一个带有“ FeuilleConge”实体(带有VichUploader)的symfony 4项目,以及一个与“ FeuilleConge”实体相关的User实体和一个Absence实体。
当我提交缺勤时,我也会在用户-> getFeuilleConge()上保留“ FeuilleConge”。
但是当我提交缺席(与FeuilleConge实体一起)时,出现此错误:
“ Symfony \ Component \ HttpFoundation \ File \ File”的序列化不是 允许
我试图向我的FeuilleConge和Absence实体添加serialize()和unserialize()方法,如下所示:
Absence.php:
/**
* @ORM\Entity(repositoryClass="App\Repository\AbsenceRepository")
* @ORM\HasLifecycleCallbacks()
* @Vich\Uploadable
*/
class Absence
{
/**
* @ORM\ManyToOne(targetEntity="App\Entity\FeuilleConge", inversedBy="absences", cascade={"persist", "remove"})
*/
private $feuilleConge;
/** @see \Serializable::serialize() */
public function serialize()
{
return serialize(array(
$this->id,
));
}
/** @see \Serializable::unserialize() */
public function unserialize($serialized)
{
list(
$this->id,
) = unserialize($serialized);
}
}

我在用户实体上添加了相同的方法。 但是问题是一样的。
有人可以帮我吗?
答案 0 :(得分:0)
您需要在User类上添加序列化方法,因为您的问题是由于Symfony试图对其进行序列化。然后,仅因为Symfony尝试序列化整个User对象(需要避免)而将您的Absence类序列化
