cakephp 3原始数据在afterSave [英] cakephp 3 original data in afterSave

问题描述

有没有办法在afterSave中访问原始数据？
我想记录重要数据的变化。

使用$ entity-> isNew（）我可以检查它是插入还是更新，

解决方案

您可以通过 Entity :: getOriginal （）或 Entity :: extractOriginal（）。如果你想得到所有改变的字段，结合后一个与 Entity :: visibleProperties（），像：

< pre class =lang-php prettyprint-override> debug（$ entity-> extractOriginal（$ entity-> visibleProperties（）））;


这应该返回所有更改字段的原始值。

另请参阅

• http：/ /api.cakephp.org/3.0/class-Cake.Datasource.EntityTrait.html#_getOriginal


• http://api.cakephp.org/3.0/class-Cake.Datasource.EntityInterface.html#_visibleProperties

Is there any way to access original data in afterSave? I would like to log the changes on important data.

With $entity->isNew() I could check if it was an insert or an update, but how can I get what changed?

解决方案

You can access the original values via Entity::getOriginal() or Entity::extractOriginal(). If you want to get all changed fields, combine the latter one with Entity::visibleProperties(), something like:

debug($entity->extractOriginal($entity->visibleProperties()));

This should return the original values of all changed fields.
