Laravel - Get Additional Attributes Of Many To Many Table

I got the following tables

• actors
  1. id
  2. name
• stats
  1. id
  2. name
• actor_stat
  1. actor_id
  2. stat_id
  3. quantity

I want, given an actor's name, take all the quantities associated.

Actor model:

class Actor extends Model
{
    public function stats()
    {
        return $this->belongsToMany('App\Stat', 'actor_stat')->withPivot('quantity');
    }

}

Stat model:

class Stat extends Model
{
    public function users()
    {
        return $this->belongsToMany('App\User', 'actor_stat')->withPivot('quantity');
    }
}

Query

    public function request(){
        $actors = Actor::where('name','Jack')->first();

        $stat = $actors->pivot->quantity; //??

        return response()->json(['actors' => $actors, 'stat' => $stat]);
    }

Suggestions?

you can use eager loading to load related table like this:

$actors = Actor::with('stats')->where('name','Jack')->first();

//do loop foreach actor state then you can access to quantity column

 foreach($actors->states as $state)
   $state->pivot->quantity;
