自动创建日期 - 注释 - Codeigniter 2 和 Doctrine 2 [英] Auto create date - annoation - Codeigniter 2 and Doctrine 2
问题描述
我将 Doctrine 2 与 Codeigniter 2 一起使用,我希望 Doctrine 在插入表中的给定字段时自动生成当前日期.
I am using Doctrine 2 with Codeigniter 2 and I would like to Doctrine automatically generate current date on insert in a given field in the table.
类文件:
<?php
namespace models;
/**
* @Entity
* @Table(name="workers")
*/
class Workers {
/**
* @Id
* @Column(type="integer", nullable=false)
* @GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @Column(type="string", length=255, unique=true, nullable=false)
*/
protected $email;
/**
* @var datetime $created_on
*
* @gedmo:Timestampable(on="create")
* @Column(type="datetime")
*/
protected $created_on;
/** @PrePersist */
function onPrePersist()
{
$this->created_on = date('Y-m-d H:i:s');
}
/* Setters & Getters */
public function setEmail($email){ $this->email = $email; }
public function getEmail(){ return $this->email; }
}
插入方法:
$worker = new models\Workers();
$worker->setEmail($data['email']);
$this->em->persist($worker);
$this->em->flush();
每次我在表 "workers" 中插入新记录时,总是有 created_on
字段 NULL
而不是插入日期.我做错了什么?
Everytime I insert new record in table "workers", there is allways created_on
field NULL
instead of insertion date. What am I doing wrong?
推荐答案
如果我错了,请纠正我.但我知道好像 Doctrine 不支持默认值.你在php级别这样做
If i am wrong, correct me please. But i knew as if Doctrine does not support default. You do that in php level like
/**
* @Column(type="string", length=255)
*/
private $something = "blabla";
查看您的源代码,我看到您正在使用 gedmo 扩展来进行学说.我对吗?所以你有两种方法可以做到这一点.
Looking at your source code, i see that you are using gedmo extension for doctrine. Am i right? So you have got two ways to do this.
1) 只使用 Doctrine,没有 Gedmo
阅读本手册非常小心,您会注意到@HasLifecycleCallbacks 注释.
1)Just using Doctrine, No Gedmo
Read this manual very carefully and you will notice @HasLifecycleCallbacks Annotations.
所以你应该编辑你的代码;
So you should edit your code as;
类文件
<?php
namespace models;
/**
* @Entity
* @Table(name="workers")
* @HasLifecycleCallbacks
*/
class Workers {
/**
* @Id
* @Column(type="integer", nullable=false)
* @GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @Column(type="string", length=255, unique=true, nullable=false)
*/
protected $email;
/**
* @var datetime $created_on
* @Column(type="datetime")
*/
protected $created_on;
/** @PrePersist */
function onPrePersist()
{
//using Doctrine DateTime here
$this->created_on = new \DateTime('now');
}
/* Setters & Getters */
public function setEmail($email){ $this->email = $email; }
public function getEmail(){ return $this->email; }
}
2) 使用 Gedmo
如果您更喜欢使用 Gedmo Timestampable 扩展,那么只需删除函数 prepersist,因为 gedmo 为您做所有事情.我还检查了我的源代码.我希望我在这里没有错误的预测
If you prefer using Gedmo Timestampable extension, then just drop the function prepersist, cause gedmo is doing everything for you. I also checked my source codes. I hope i do not have wrong predictions here

protected $created_on;
/* Setters & Getters */
public function setEmail($email){ $this->email = $email; }
public function getEmail(){ return $this->email; }
}
