如何将bigIncrements('id')转换为uuid('id')作为主键？

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

class YourModel extends Model
{
    use \Illuminate\Database\Eloquent\SoftDeletes;
    use \App\Traits\UsesUuid; // 添加这一行

    // ...
}

<?php

namespace App\Traits;

use Illuminate\Support\Str;

trait UsesUuid
{
    /**
     * Boot function from Laravel.
     */
    protected static function bootUsesUuid()
    {
        static::creating(function ($model) {
            if (! $model->getKey()) {
                $model->{$model->getKeyName()} = (string) Str::uuid();
            }
        });
    }

    /**
     * Get the value indicating whether the IDs are incrementing.
     *
     * @return bool
     */
    public function getIncrementing()
    {
        return false;
    }

    /**
     * Get the type of the primary key.
     *
     * @return string
     */
    public function getKeyType()
    {
        return 'string';
    }
}

composer require ramsey/uuid

php artisan migrate
