python - 运行时错误: maximum recursion depth exceeded in Odoo 10

Question

我是 odoo 新手，当我在继承的 sale_order_line 类中添加函数时收到此错误。下面是代码。您能告诉我我在哪里犯了错误吗？

class SaleOrderLine(models.Model):
    _inherit = 'sale.order.line'

    product_id = fields.Many2one('product.product', string='Product', domain=[('sale_ok', '=', True)],
                             change_default=True, ondelete='restrict', required=True)

    salesman_id = fields.Char(string='Salesman')

    @api.onchange(product_id)
    @api.depends(salesman_id)
    def user_id_tracking(self):
        self.env.cr.execute("""SELECT user_id FROM stock_location as sl WHERE sl.id in
        (SELECT sq.location_id FROM stock_change_product_qty as sq,product_template as pt
        WHERE sq.product_id = %d)""", self.product_id)
        res = self.env.cr.fetchone()
        self.salesman_id = res[0]

    lot_id = fields.Many2one('stock.production.lot', string='Lot/Serial Number', copy=False)

Answer 1

您告诉 odoo 在更改 salesman_id 时触发此函数，并且在该函数内更改相同的字段，以便 odoo 将继续调用您的方法。

remove depends decorator because you are using it the wrong way use it only for compute field.

只需保持onchange，并且永远不要设置您依赖计算字段值的同一字段。
