当方法返回null

Question

我有两个模型，一个叫Customer第二个是Website

它们之间的关系是， Customer Website而Website属于Customer

这就是我这样做的方式

class Website extends \Eloquent {
    use SubscriptionBillableTrait;

    protected $fillable = [];

    protected $guarded = ['id'];

    public function customermodel()
    {
        // Return an Eloquent relationship.
        return $this->belongsTo('Customer')
    }

}

Customer模型

use Mmanos\Billing\CustomerBillableTrait;
class Customer extends \Eloquent {
    use CustomerBillableTrait;
    protected $fillable = [];

    protected $guarded = ['id'];

    public function websites() {
        return $this->hasMany('Website');
    }

}

当我尝试通过这样的关系访问Customer

$website = Website::find(1);
return dd($website->customermodel);

返回null

注意：我正在使用Laravel 4
