Php 如何从Phalcon中的相关表中获取数据？

我的结构与phalcon模型文档中的结构完全相同：

在我实现的模型中，有许多行：

机器人型号：

class Robots extends \Phalcon\Mvc\Model
{
    public $id;
    public $name;
    public function initialize(){
        $this->hasMany("id", "RobotsParts", "robots_id");
    }
}

零件型号：

class Parts extends \Phalcon\Mvc\Model
{
    public $id;
    public $name;
    public function initialize(){
        $this->hasMany("id", "RobotsParts", "parts_id");
    }
}

class RobotsParts extends \Phalcon\Mvc\Model
{
    public $id;
    public $robots_id;
    public $parts_id;
    public function initialize(){
        $this->belongsTo("robots_id", "Robots", "id");
        $this->belongsTo("parts_id", "Parts", "id");
    }
} 

机器人零件型号：

class Parts extends \Phalcon\Mvc\Model
{
    public $id;
    public $name;
    public function initialize(){
        $this->hasMany("id", "RobotsParts", "parts_id");
    }
}

class RobotsParts extends \Phalcon\Mvc\Model
{
    public $id;
    public $robots_id;
    public $parts_id;
    public function initialize(){
        $this->belongsTo("robots_id", "Robots", "id");
        $this->belongsTo("parts_id", "Parts", "id");
    }
} 

此时，我希望通过调用RobotParts:：find（）来获取所有数据，但我只能看到id。 对于调试，我转储了，但只找到ID:(

我希望得到这样的结果：

array (size=1)
  0 => 
    array (size=7)
      'id' => int '1' (length=1)
      'robots_id' => int '4' (length=1)
          'name'  => string 'r2d2' (length=4)
          'type'  => string 'droid' (length=5)
          'year'  => int '2184' (length=4)
      'parts_id' => int '4' (length=1)
          'name'  => string 'wheel' (length=5)

var_dump（）不包含从视图引用它所需的相关表，如：

robots.RobotParts.name
