Mysql Laravel 4和具有多个表的雄辩查询（带）

我是拉威尔发展公司的新员工， 我有代码问题

我有这样的MotorsController.php

我有如下模型

Motor.php

<?php

 class Motor extends Eloquent {
protected $table = 'motors';
protected $guarded = array();

public function motorcategory(){
    return $this->belongsTo('MotorCategory');
}
public function motorcolor(){
    return $this->belongsTo('MotorColor');
}

public static $rules = array(
    'name' => 'required',
    'police_number' => 'required',
    'sex' => 'required'

);
}

在motors.index中，我想获得与表motor_分类和motor_颜色相关的电机数据

但现在我仍然有这样的错误：

BadMethodCallException 
Call to undefined method Illuminate\Database\Query\Builder::motor_category()

我希望有人能帮助我。。 顺便说一句，对不起我的英语：

motors.index中的代码是什么？我已经准备好编辑这篇文章以添加motors.index删除下划线。使用“motorcategory”、“motorcolor”感谢Marweln。。现在是工作时间。。

class MotorColor extends Eloquent {
    //protected $fillable = array('name','semua fieldnya kah ? ','cateogory_id');
    public function motor(){
        return $this->hasMany('Motor');
    }
}
