在 eloquent 中自动获取时重命名关系名称

Question

    class Order extends Elequent{
        protected $table = 'order';
        const CREATED_AT = "createdAt";
        const UPDATED_AT = "updatedAt";

        protected $with = array('orderItem', 'address');
        public function orderItem(){
            return $this->hasMany("OrderItem","orderId");
        }
        public function address(){
            return $this->hasOne("OrderAddress","orderId","id");
        }
    }

    //in controller
    $order = Order::findOrFail($orderId);
    echo $order;

当使用上面的 class 将订单序列化为 json 时，我怎样才能将 order_item 设置为 orderItem（我更喜欢骆驼案例而不是蛇案例）

{
  "id": 1,
  "userId": 1,
  "createdAt": "2015-04-30 12:08:26",
  "deletedAt": "0000-00-00 00:00:00",
  "updatedAt": "2015-04-30 12:08:26",
  "state": "activated",
  "deliveryNote": null,
  "order_item": [
    {
      "id": 1,
      "specialProductId": 29,
      "volume": 750,
      "quantity": 2,
      "price": "543.38",
      "orderId": 1,
      "updatedAt": "2015-04-30 12:08:26",
      "createdAt": "2015-04-30 12:08:26"
    }
  ],
  "address": null
}

Answer 1

您可以 copy/rename 对象属性并取消设置旧对象。

//in controller

$order = Order::findOrFail($orderId);

$order->orderItem = $order->order_item;
unset($order->order_item);

echo $order;

为了更好的使用，你可以把这个方法放在你的基础模型上，

public function toArrayCamel()
{
    $array = $this->toArray();

    foreach($array as $key => $value)
    {
        $return[camel_case($key)] = $value;
    }

    return $return;
}

稍后在您的控制器上，

$order = Order::findOrFail($orderId);

return Response::json( $order->toArrayCamel() );

Answer 2

在您的模型中，将 $snakeAttributes 属性设置为 false。这将在生成数组时防止属性 snake_cased。

class Order extends Elequent {

    public static $snakeAttributes = false;

}
