POS 订单产品总计

Question

我的目标是在产品表单视图中添加一个字段，以显示使用 POS 购买此产品的次数。真的坚持这个，并且很高兴知道如何做到这一点。

class Product(models.Model):
    _inherit = 'product.product'

    pos_product_order_total = fields.Char(
        string='Product POS Orders', compute='_product_pos_orders')

    def _product_pos_orders(self):
        Order = self.env['pos.order']
        for product in self:
            domain = [('product_id', '=', product.id)]
            for o in Order.search(domain):
                pass

尝试以下解决方案：

class Product(models.Model):
    _inherit = 'product.product'

    pos_product_order_total = fields.Char(
        string='Product POS Orders', compute='_product_pos_orders')

    def _product_pos_orders(self):
        OrderLine = self.env['pos.order.line']
        for product in self:
            domain = [('product_id', '=', product.id)]
            product.pos_product_order_total = sum(OrderLine.search(domain).mapped('qty'))
