SonataAdminBundle - preUpdate [英] SonataAdminBundle - preUpdate

问题描述

是否可以检查字段是否在 preUpdate 钩子？我正在寻找像 preUpdate hasChangedField（$ fieldName） Doctrine功能。任何想法？

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?

推荐答案

这个问题有点类似于这一个

您的解决方案只是为了比较字段的旧对象与新的对象，看看它在哪里。

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

所以例如：

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

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