odoo 8.0のコンテキストを使用して、デフォルトでsales orderlineの受注フィールドを表示する方法は？

Question

sales.order.lineのsales_shipというフィールドと、ship_saleという名前のフィールドがあります。今私がしたいのは、デフォルトでsale.order.lineのship_saleにデフォルトで来るsales.order内の選択されたsales_shipを持つことです。どのようにコンテキストを使用してそれを行うには？ここに私のフルコードです。

py。

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')
