odoo 11企业联邦快递获得多种运费

Question

加拿大的航运公司整合：

提前抱歉如果我在这篇文章中犯了任何错误，因为这是我的第一次。

我最初要做的是：

1. 已为加拿大邮政，Purolator和FedEx创建了3个模块，其中有One2many的选股表格视图，并点击当前发货的获取费率（包装部分未完成，请忽略。请检查图像为Purolator部分）< / LI>
2. 使用odoo 11企业版的默认delivery_fedex模块并修改其_fedex_get_rate（）方法，以便获得所有服务的费率（使用gst，hst等）
3. 对于FedEx，公司地址来自加拿大，客户来自美国/国际地址。

那么，在我的FedEx模块中我应该更改哪些内容和哪里可以获取多个费率？

方法我试图写入stock.picking以获得按钮上的费率：

def get_fedexrule_schema(self):    
    fedex_search = self.env['delivery.carrier'].search([('delivery_type','=','fedex'),('name','=','Fedex US')])

    picking = self.env['stock.picking']

    cache_interval = int(time.time() / (4 * 3600))

    print('fffffffff',fedex_search)
    # self, environment, account_number, meter_number, droppoff_type, service_type,
    # package_code, weight_unit, fedex_saturday_delivery, order_name, currency_name,

    # current_fed = fedex_search.id
    # , , meter_number, droppoff_type, service_type,
    # package_code, weight_unit, fedex_saturday_delivery, order_name, currency_name,

    fedex_saturday_delivery =fedex_search.fedex_saturday_delivery
    order_name=  self.sale_id.name
    currency_name=  self.sale_id.currency_id.name

    # fed_ =fedex_search.order_name)
    # print('>>>>>>>>>>>>>>>>>',fedex_search.currency_name)
    shipper_company=(self.company_id.partner_id.id,self.company_id.partner_id['__last_update'])
    shipper_warehouse = (self.picking_type_id.warehouse_id.partner_id.id,self.picking_type_id.warehouse_id.partner_id['__last_update'])
    recipient = (self.partner_id.id,self.partner_id['__last_update'])
    fedex_rate= self.env['delivery.carrier']._fedex_get_rate('test', fedex_account_number, fedex_meter_number, fedex_droppoff_type,fedex_default_packaging_id.id,fedex_service_type,
                                                        fedex_weight_unit, True, order_name, currency_name,shipper_company, shipper_warehouse, recipient, 10,20,cache_interval)
    print("fedex_rate>>>>>>>>",fedex_rate)
