任何人都可以告诉我在odoo中究竟是什么with_context? 如果我想从价目表中得到价格,我会这样编码。

product = self.product_id.with_context(
                lang=self.order_id.partner_id.lang,
                partner=self.order_id.partner_id.id,
                quantity=self.product_uom_qty,
                date=today_date,
                pricelist=self.order_id.pricelist_id.id,
                uom=self.product_uom.id,
                fiscal_position=self.env.context.get('fiscal_position'))
 price_unit = self._get_display_price(product) 

@api.multi
def _get_display_price(self, product):
    # TO DO: move me in master/saas-16 on sale.order
    if self.order_id.pricelist_id.discount_policy == 'with_discount':
        return product.with_context(pricelist=self.order_id.pricelist_id.id).price
    final_price, rule_id = self.order_id.pricelist_id.get_product_price_rule(self.product_id, self.product_uom_qty or 1.0, self.order_id.partner_id)
    context_partner = dict(self.env.context, partner_id=self.order_id.partner_id.id, date=self.order_id.date_order)
    base_price, currency_id = self.with_context(context_partner)._get_real_price_currency(self.product_id, rule_id, self.product_uom_qty, self.product_uom, self.order_id.pricelist_id.id)
    if currency_id != self.order_id.pricelist_id.currency_id.id:
        base_price = self.env['res.currency'].browse(currency_id).with_context(context_partner).compute(base_price, self.order_id.pricelist_id.currency_id)
    # negative discounts (= surcharge) are included in the display price
    return max(base_price, final_price)

那么product = self.product_id.with_context()究竟是什么让我付出代价。它要求哪种方法获得价格?

首先你必须知道selfoo.env.context在odoo中是什么

上下文是一个python字典,用于将某些数据传递给方法,其类型为FrozenDict inmutable。

当您在调用方法时需要更新或向de context添加新密钥时,必须使用with_context。

Context用于传递方法调用的参数。从xml到paython 许多odoo方法根据上下文中的键改变那里的值:

示例:

       # this return available quantity of the product in all location
       quantity = product.qty_available
       # this return avaible quantity for a specific location
       quantity = product.with_context('location' : location_id).qty_available

with_context用于添加或更新上下文的键
