Laravel模型中的默认随机值

Question

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.

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.

Override the save method of your model:

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