自动创建日期 - 烦恼 - Codeigniter 2和Doctrine 2 [英] Auto create date - annoation - Codeigniter 2 and Doctrine 2

问题描述

我正在使用Doctrine 2与Codeigniter 2，我希望Doctrine自动生成当前日期插入表中的给定字段。

CLASS FILE：

 <？php 
命名空间模型; 
 
 / ** 
 * @Entity 
 * @Table（name =workers）
 * / 
 class Workers {
 / ** 
 * @Id 
 * @Column（type =integer，nullable = false）
 * @GeneratedValue（strategy =AUTO）
 * / 
保护$ 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（'Ymd H：i ：s'）; 
} 
 
 / * Setters& Getters * / 
 public function setEmail（$ email）{$ this-> email = $ email; } 
 public function getEmail（）{return $ this-> email; } 
} 
  

INSERT METHOD：

  $ worker = new models\Workers（）; 
 $ worker-> setEmail（$ data ['email']）; 
 $ this-> em-> persist（$ worker）; 
 $ this-> em-> flush（）; 
  

每当我在表工作者中插入新记录时，都会有code> created_on 字段 NULL 而不是插入日期。我做错了什么？

解决方案

如果我错了，请更正我。但我知道如果教义不支持默认。你这样做在php级别像

  / ** 
 * @Column（type =string，length = 255）
 * / 
 private $ something =blabla; 
  

看看你的源代码，我看到你正在使用gedmo扩展的原则。我对吗？

1）只使用Doctrine，No Gedmo

读取< a href =http://www.doctrine-project.org/docs/orm/2.0/en/reference/annotations-reference.html =noreferrer>本手册非常仔细，你会注意到@HasLifecycleCallbacks注释。

所以你应该编辑你的代码;

CLASS FILE

 <？php 
命名空间模型; 
 
 / ** 
 * @Entity 
 * @Table（name =workers）
 * @HasLifecycleCallbacks 
 * / 
类工人{
 / ** 
 * @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 * / 
函数onPrePersist（）
 {
 //使用Doctrine DateTime这里
 $ 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

如果你喜欢使用Gedmo Timestampable扩展，那么只需放弃函数prepersist，因为gedmo正在为你做的一切。我也检查了我的源代码。我希望我在这里没有错误的预测。

类文件

 <？php 
命名空间模型; 
 
 / ** 
 * @Entity 
 * @Table（name =workers）
 * / 
 class Workers {
 / ** 
 * @Id 
 * @Column（type =integer，nullable = false）
 * @GeneratedValue（strategy =AUTO）
 * / 
保护$ id; 
 
 / ** 
 * @Column（type =string，length = 255，unique = true，nullable = false）
 * / 
 protected $ email ; 
 
 / ** 
 * @var datetime $ created_on 
 * @Column（type =datetime）
 * @gedmo：Timestampable（on =create ）
 * / 
 protected $ created_on; 
 
 / * Setters& Getters * / 
 public function setEmail（$ email）{$ this-> email = $ email; } 
 public function getEmail（）{return $ this-> email; } 
} 
  

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.

CLASS FILE:

<?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; }
}

INSERT METHOD:

$worker = new models\Workers();
$worker->setEmail($data['email']);
$this->em->persist($worker);
$this->em->flush();

Everytime I insert new record in table "workers", there is allways created_on field NULL instead of insertion date. What am I doing wrong?

解决方案

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";

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)Just using Doctrine, No Gedmo
Read this manual very carefully and you will notice @HasLifecycleCallbacks Annotations.

So you should edit your code as;

CLASS FILE

<?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)Using Gedmo

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

CLASS FILE

<?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
  * @Column(type="datetime")
  * @gedmo:Timestampable(on="create")
  */
protected $created_on;

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