odoo 8.0에서 컨텍스트를 사용하여 판매 주문 라인에 판매 주문 필드를 표시하는 방법은 무엇입니까?

Question

sales.order.line에서 sales_ship이라는 필드와 ship_sale이라는 필드가 있습니다. 이제 내가 원하는 것은 기본적으로 sales.order.line의 ship_sale에서 sales.order의 선택된 sales_ship을 기본적으로 사용하도록하는 것입니다. 문맥을 사용하여 그것을하는 방법? 여기 내 전체 코드입니다.

from openerp import models , fields 


class ShipInfo (models.Model): 
    _name = "ship.ship" 
    imo = fields.Char (string = "IMO" , size = 64 , required = True) 
    hull_number = fields.Char (string = ' Hull Number ' , size = 64 , required = True) 
    engine_number = fields.Char (string = ' Engine Number ' , size = 64 , required = True) 
    vessel_name = fields.Char (string = 'Vessel Name' , size = 64) 
    build_year = fields.Char (string = 'Build Year' , size = 64) 

    ship_yard = fields.Many2one ('res.partner' , string = 'Ship Yard') 
    ship_owner = fields.Many2one ('res.partner' , string = 'Ship Owner') 
    ship_management = fields.Many2one ('res.partner' ,string= 'Ship Management') 
    engine_builder = fields.Many2one ('res.partner' , string = 'Engine Builder') 
    _rec_name = 'vessel_name' 


class SaleOrderInherited (models.Model): 
    _inherit = 'sale.order' 
    sales_ship = fields.Many2one ('ship.ship' , string = 'Sales Ship') 

class SaleOrderLineInherited (models.Model): 
_inherit = 'sale.order.line' 
ship_sale = fields.Many2one ('ship.ship' , string = 'Sales Ship')
