Doctrine - 向实体添加默认时间戳，如 NOW()
遵循 Doctrine 指南，我了解如何为实体设置默认值，但如果我想要日期/时间戳怎么办?
Following the Doctrine guidelines I understand how to set a default value for an Entity, but what if I wanted a date/time stamp?
- http://docs.doctrine-project.org/projects/doctrine-orm/en/2.1/reference/faq.html
我的问题是我的数据库在一个字段上有一个默认值 NOW() 但是当我使用 Doctrine 插入记录时，值是空或空白，但插入的其余部分发生了.
My problem is my database has a default of NOW() on a field but when I use Doctrine to insert a record the values are null or blank but the rest of the insert happened.
此外，由于 Doctrine 说要将默认值声明为常量，这也会产生问题.
Also since Doctrine says to declare the default as a const, this also creates a problem.
建议?
推荐答案
好的，我找到了解决方案:
Ok I found the solution:
- https://doctrine-orm.readthedocs.org/en/latest/reference/php-mapping.html?highlight=callback
- http://doctrine-orm.readthedocs.org/en/latest/reference/events.html#lifecycle-events
prePersist 选项就是我正在做的.
The prePersist option is what I'm doing.
确保在注释中定义
<?php
/** @Entity
* @HasLifecycleCallbacks
*/
class User
这是他们提供的功能示例
and here is the function example they offer
/**
* @PrePersist
*/
public function doStuffOnPrePersist()
{
$this->createdAt = date('Y-m-d H:i:s');
}
如果你像我一样使用 ORM
And if you're using ORM like I am
<?php
/** @ORMEntity
* @ORMHasLifecycleCallbacks
*/
class User
这是他们提供的功能示例
and here is the function example they offer
/**
* @ORMPrePersist
*/
public function doStuffOnPrePersist()
{
$this->createdAt = date('Y-m-d H:i:s');
}
