关系viaTable yii2

Question

我有3个表格（order，order_delivery，order_types）。每张桌子都有模特。对于订单我创建GridView。表格order包含列order_number，表order_delivery包含order_number和order_delivery_code，表格order_type包含delivery_types_code和delivery_types_name }。按顺序我写函数

public function getType() {
    return $this->hasOne(OrderDelivery::className(), ['order_id' => 'order_id']) 
        ->viaTable('delivery-types', ['delivery-types_code' => 'order_delivery_code']); 
}

在index我写type.delivery-types_name - 有

  

获取未知属性：backend \ models \ Order :: order_delivery_code

我做错了什么？

UPD。我的错）

public function getType(){
    return $this->hasOne(DeliveryTypes::className(), ['delivery-types_code' => 'order_delivery_code'])
        ->viaTable('order_delivery', ['order_id' => 'order_id']);
}
