自定义created_at，仅使用自定义created_at [英] Custom created_at and use only custom created_at

问题描述

我是Laravel的新手.

I am new to Laravel.

我想使用自定义字段名称(例如ct，而不使用updated_at)为Laravel中的所有插入操作添加时间戳.

I want to add timestamp for all insert actions in Laravel using custom field name such as ct and not using updated_at.

我想出了下面的方法，但是没有运气.我所有的表都具有带有not null属性的ct字段.

I came up with below, but without luck. All of my tables have ct field with not null property.

class ProductLog extends Model
{
    const CREATED_AT = 'ct';

    public $timestamps = false;

    public static function boot()
    {
        parent::boot();

        static::creating(function ($model) {
            $model->created_at = $model->freshTimestamp(); => 1)
            $model->setCreatedAt($model->freshTimestamp()); => 2)
        });
    }
}

1)和2)都仍然抛出一个错误，说'ct'没有默认值.

Both of 1) and 2) still throws me an error saying 'ct' doesn't have a default value.

任何建议或建议都将不胜感激.

Any suggestion or advice would be appreciated.

谢谢.

推荐答案

我刚刚对此进行了测试，并且效果很好:

I've just tested this and it works perfectly:

const UPDATED_AT = null;
const CREATED_AT = 'ct';

无需执行任何其他操作.使用此解决方案，Laravel将ct用作created_at，并且不会将updated_at添加到任何更新查询中.

There's no need to do anything else. With this solution, Laravel will use ct as created_at and will not add updated_at to any update queries.
