我有一个名为 RecordsUserActivity 的特征，它基本上在用户创建、更新或删除使用此特征的内容时在活动表中创建一条记录。这是代码：

trait RecordsUserActivity
{
    protected static function boot()
    {
        parent::boot();
        foreach (static::getModelEvents() as $event) {
            static::$event(function ($model) use ($event) {
                $model->addActivity($event);
            });
        }
    }

    protected function addActivity($event)
    {
        $newActivity = [
            'subject_id' => $this->id,
            'subject_type' => get_class($this),
            'action' => $event,
            'user_id' => (Auth::id()) ?? null,
        ];

        if ($event == 'updated') {
            $newActivity['data'] = json_encode($this->getDirty());
        }

        UserActivity::create($newActivity);
    }

    protected static function getModelEvents()
    {
        if (isset(static::$recordEvents)) {
            return static::$recordEvents;
        }

        return ['created', 'deleted', 'updated'];
    }
}

然后我有另一个特征，它记录使用它的模型中的属性更改。这是代码：
