问题描述

有人可以告诉我如何在datetime列上添加默认值?我不能这样做:

  protected $ registration_date = date(Ymd H:i:s,time )); 

那么如何?

解决方案

将属性映射为DateTime类型,然后使用新的DateTime实例在构造函数中设置值:

  / ** 
* @Entity
* @Table(name =...)
* /
class MyEntity
{
/ * * @Column(type =datetime)* /
protected $ registration_date;

public function __construct()
{
$ this-> registration_date = new DateTime();
}
}

这作为持久化类的构造函数不是要求水合。


Could someone tell me how to add default value on datetime column? I can't do this like this:

protected $registration_date = date("Y-m-d H:i:s", time());

So how?

解决方案

You map your property as DateTime type then set the value in the constructor using a new DateTime instance:

/**
 * @Entity
 * @Table(name="...")
 */
class MyEntity
{
    /** @Column(type="datetime") */
    protected $registration_date;

    public function __construct()
    {
        $this->registration_date = new DateTime(); 
    }
}

This works as the constructor of a persisted class is not called upon hydration.
