Schema::create('posts', function (Blueprint  $table) {
    $table->luuid(); // you can also custom your luuid `luuid('post_id')`
    $table->string('title');
    $table->string('body');
    $table->timestamps();
});

在你的Model中使用 WithUuid 特性并声明主键

示例

namespace  App;

use HaymeTG\LUUID\Traits\WithUuid;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
	use WithUuid;
	protected $primaryKey = 'uuid';
}

完成！每次保存新记录时，它将自动生成唯一的UUID。
