谁能告诉我 with_context 在 odoo 中究竟做了什么?如果假设我想从价目表中获取价格,我会做这样的代码。
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)
那么到底product = self.product_id.with_context()
该怎么做才能让我付出代价。它调用哪种方法来获取价格?
