调用一个成员函数助理（）在非对象

Question

错误消息：http://puu.sh/d4l0F/5b0ac07e68.png

我甚至试图建立关联之前，节省了$运输对象。我已经验证了$ transporation，$ from和$ to都是它们各自的对象，它们是。

我确定我在这里错过了一些愚蠢的东西，但我没有想法。

我的代码：

class RideBuilder implements RideBuilderInterface 
{ 
    public function create(Advance $advance) 
    { 
     $ride = new Ride; 
     if($ride->validate(Input::all())) { 
      $ride->save(); 

      $to = Location::find(Input::get('dropoffLocation')); 
      $from = Location::find(Input::get('pickupLocation')); 

      $transportation = new Transportation; 
      $transportation->save(); 

      $transportation->transportable()->associate($ride); 
      $transportation->to()->associate($to); 
      $transportation->from()->associate($from); 

      $event = new Event; 
      $event->start = Input::get('ridePickUpTime'); 
      $event->save(); 

      $event->eventable->save($transportation); 
      $event->subjectable->save($advance); 
     } 
     return $ride; 
    } 
} 

选址模型：

class Location extends Elegant 
{ 
protected $table = 'locations'; 

public $rules = array(
    'label'   => 'required|min:2', 
    'street'  => 'required', 
    'city'   => 'required', 
    'state'   => 'required', 
    'type'   => 'required', 
); 

public function advance() 
{ 
    return $this->belongsTo('Booksmart\Booking\Advance\Model\Advance'); 
} 

public function locationable() 
{ 
    return $this->morphTo(); 
} 

} 

运输型号：

class Transportation extends Elegant 
{ 
    protected $table = 'transportations'; 

    public function event() 
    { 
     $this->morphOne('Booksmart\Component\Event\Model\Event'); 
    } 

    public function start_location() 
    { 
     $this->belongsTo('Booksmart\Component\Location\Model\Location', 'start_location'); 
    } 

    public function end_location() 
    { 
     $this->belongsTo('Booksmart\Component\Location\Model\Location', 'end_location'); 
    } 
}

我有一个类似的问题。我犯了一个愚蠢的错误，在关系方法中不加入“返回”！

确保返回的关系......显然，这将不工作：

public function medicineType() 
    { 
     $this->belongsTo('MedicineType', 'id'); 
    } 

这是正确方式：

public function medicineType() 
    { 
     return $this->belongsTo('MedicineType', 'id'); 
    } 

容易错过，难以调试...
