Laravel5.5 对模型进行全局作用域限制后使用 hasManyThrough 模型关系时,若关联表作用域限制字段相同会报 MySQL 错误

版本 :laravel 5.5.44 /mysql 5.7
错误:mysql联表时存在相同字段未指定表名
场景:存在三个Model,分别为Script Channel News 三个模型均在boot方法中设置了全局作用域限制site_id为用户所属site_id

    $site_id = $user->site_id ?? 0;
    static::addGlobalScope('site_id', function(Builder $builder) use ($site_id) {
        $builder->where('site_id', $site_id);
    });

在Script中存在hasManyThrough模型关系

    public function channel(){
        return $this->hasManyThrough('App\Models\Channel', 'App\Models\News', $this->foreignKeyName, 'id', 'id', 'channel_id');
    }

调用$script->channel时报错如下:

"SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'site_id' in where clause is ambiguous (SQL: select channels.*, news.script_id from channels inner join news on news.channel_id = channels.id where news.deleted_at is null and news.script_id = 182 and channels.deleted_at is null and site_id = 262)"

查看日志发现好像所有的全局作用域在生成SQL语句时都不限定表名的,请问该如何解决?这是否属于laravel的bug?
