    You need to define your relationships like below:

    class Part extends Model
    {
        public function cards()
        {
            return $this->belongsToMany('App\Cards', 'user_cards');
        }
    }
    

    Then you can fetch all the cards for a part like below:

    $cards = Part::with('cards')->find($part_id);
