Symfony 4 - 不允许 VichUploader 序列化"Symfony\Component\HttpFoundation\File\File"

Question

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Absent实体。

当我提交缺席时，我也在我的User->getFeuilleConge((上保留"FeuilleConge"。

但是当我提交缺席(带有FeuilleConge实体(时，我有这个错误：

'Symfony\Component\HttpFoundation\File\File' 的序列化不是 允许

我尝试将 serialize(( 和 unserialize(( 方法添加到我的 FeuilleConge 和 Absence 实体中，如下所示：

缺席.php：

/**
* @ORMEntity(repositoryClass="AppRepositoryAbsenceRepository")
* @ORMHasLifecycleCallbacks()
* @VichUploadable
*/
class Absence
{
/**
* @ORMManyToOne(targetEntity="AppEntityFeuilleConge", 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。 但问题是一样的。

有人可以帮我吗？

你需要在你的User类上添加序列化方法，因为你的问题是由于Symfony试图序列化它。然后，您的Absent类被序列化，只是因为Symfony尝试序列化整个User对象(您需要避免(
