评论关联用户信息表

public function toUser(){

    }

评论的监听和删除

public static function boot()
    {
        parent::boot();

        /*监听创建*/
        static::creating(function($comment){
            /*开启状态检查*/
            if(Setting()->get('verify_comment')==1){
                $comment->status = 0;
            }
        });

        /*监听删除事件*/
        static::deleting(function($comment){
            /*问题、回答、文章评论数 -1*/
            $comment->source()->where("comments",">",0)->decrement('comments');
