使用laravel。我在mysql数据库中有下面的表。
infos表接受1个中介（表中介）和1个存储（表存储）。如何从infos表中获取所有数据？但仅当透视表（中间存储）处于活动状态时=1？

infos
- id
- name
- intermediary_id
- store_id

intermediaries
- id
- name

intermediary_store
- intermediary_id
- store_id
- active

stores
- id
- name

模型：

class Info extends Model
{
    public function intermediary()
    {
        return $this->belongsTo('App\Intermediary');
    }

    public function store()
    {
        return $this->belongsTo('App\Store');
    }
}

class Intermediary extends Model
{
    public function stores()
    {
        return $this->belongsToMany('App\Store')->withPivot('active');
    }
}

class Store extends Model
{
    public function intermediaries()
    {
        return $this->belongsToMany('App\Intermediary')->withPivot('active');
    }
}
