Laravel模型中的默认随机值 [英] Default random value in Laravel models

问题描述

我正在尝试为Laravel模型设置一个随机默认值，以便在用户注册时为每个用户将一个随机值保存到数据库中.

I am trying to set up a random default value for a Laravel model so that when a user registers a random value is saved to the database for each user.

我看过类似的

I've looked at similar question on StackOverflow which explains how to setup a default value using the $attributes variable but it doesn't explain the random bit.

推荐答案

覆盖模型的save方法:

public function save(array $options = array())
{
    if(empty($this->id)) {
        $this->someField = rand();
    }
    return parent::save($options);
}
