使用touch()更新laravel中自定义时间戳字段的时间戳 [英] using touch() to update timestamp of custom timestamp field in laravel

问题描述

是否可以使用touch()更新表中is_online字段的时间戳，而不是更新 laravel Eloquent ORM

Is there a way to use touch() for updating timestamp of is_online field in table instead of updating created_at field in laravel Eloquent ORM

目前我正在使用

User::where('id',$senderId )->update(array('is_online' => date('Y-m-d H:i:s')));

推荐答案

不，touch方法不是用于更新除内置时间戳记之外的任何东西，但是如果您愿意，可以在用户模型中编写自己的函数想要.像这样

No, the touch method isn't written for updating anything other than the built in timestamps, but you could write your own function in your User Model, if you want to. Something like this

class User extends Eloquent implements UserInterface, RemindableInterface {

    public function touchOnline()
    {
        $this->is_online = $this->freshTimestamp();
        return $this->save();
    }
}

然后将您的旧代码替换为

and then do replace your old code with

User::find($senderId)->touchOnline();

多几行代码，但可读性更高.

A few more lines of code, but maybe a slight bit more readable.
