SonataAdminBundle-检查`preUpdate`挂钩中的更改 [英] SonataAdminBundle - check changes in `preUpdate` hook

问题描述

是否可以检查 preUpdate 挂钩？我正在寻找类似 preUpdate hasChangedField（$ fieldName）教义功能。有任何想法吗？

Is it possible to check if field was changed on preUpdate hook? I'm looking for something like preUpdate hasChangedField($fieldName) Doctrine functionality. Any ideas?

您的解决方案只是比较领域

Your solution is just to compare the field of the old object with the new one and see where it differs.

因此，例如：

public function preUpdate($newObject)
{
    $em = $this->getModelManager()->getEntityManager($this->getClass());
    $originalObject = $em->getUnitOfWork()->getOriginalEntityData($newObject);

    if ($newObject->getSomeField() !== $originalObject['fieldName']) {
        // Field has been changed
    }
}
