Laravel-permission 新建 MyPermission 模型，赋予角色权限时，permission_id 会变成 my_permission_id ？

用的 laravel-permission 扩展包，新建 MyPermission 模型，赋予角色权限时，permission_id 会变成my_permission_id ？
我在控制器中调用：

$res = MyPermission::create($pm);
//角色 menu 添加对应权限
$role = MyRole::findByName('menu');
$res->assignRole($role); // 这里就出现 插入的字段是 my_permission_id 而不是 permission_id

Mypermission模型：

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\DB;
use Spatie\Permission\Exceptions\PermissionAlreadyExists;
use Spatie\Permission\Guard;
use Spatie\Permission\Models\Permission;
use Spatie\Permission\Models\Role;

class MyPermission extends Permission
{
    /**
     * 重写 permission 的 create 方法，添加了 display_name pm_description pm_type 三个字段
     * @param array $attributes
     * @return $this|Model
     */
    public static function create(array $attributes = [])
    {
        $attributes['guard_name'] = $attributes['guard_name'] ?? Guard::getDefaultName(static::class);

        $permission = static::getPermissions()->filter(function ($permission) use ($attributes) {
            return $permission->name === $attributes['name'] && $permission->guard_name === $attributes['guard_name'];
        })->first();

        if ($permission) {
            throw PermissionAlreadyExists::create($attributes['name'], $attributes['guard_name'], $attributes['display_name'], $attributes['pm_description'], $attributes['pm_type']);
        }

        if (isNotLumen() && app()::VERSION < '5.4') {
            return parent::create($attributes);
        }

        return static::query()->create($attributes);
    }

}
