i'm having a problem with Laravel 5 and Eloquent. I have 3 models called Ad, AdEngine and Engine:

```
class Ad 
{
    ...
    public function engineAd()
    {
        return $this->belongsTo('App\Models\EngineAd', 'engine_ad_id', 'id');
    }
    ...
}

class EngineAd 
{
    ...
    public function engine()
    {
        return $this->belongsTo('App\Models\Engine', 'engine_id', 'id');
    }
    ...
}

class Engine {...}

```

Inside my Ad Class, i have a method called title that uses the relation belongsTo, like this:

```
public function title() 
{
    return $this->engineAd->engine->title;
}

```

For the first relation Ad -> AdEngine i used eager loading to get all AdEngine:

```
$ads = Ad::with('engineAd');

```

But for the relation AdEngine -> Engine, Laravel generates an extra query for every iteration, can i use eager loading or something like this here too?

```
select * from `engine` where `engine`.`id` = '1' limit 1
select * from `engine` where `engine`.`id` = '2' limit 1
select * from `engine` where `engine`.`id` = '3' limit 1

```

Thanks.
