这是我的Python代码。它继承了hr.employee，res.partner和sale.order。

在更改customer_id时，页面必须在树视图中仅使用两个字段（员工姓名和员工评级）加载员工详细信息。这些字段是第一次正确加载，但是当我更改客户ID时，树视图字段没有更新。
答案 0 :(得分：0)
尝试使用openerp.osv.orm.BaseModel（V7）或openerp.models.Model（V8 +）中def write下记录的“幻数”：
def on_change_partner_id(self, ...):
# ...
emp_tuple_list=[(5,)] # without (5,) it won't delete all old data
for emp in part.employee_ids:
emp_tuple_list.append((4, emp.id))
val.update({'employee_ids': emp_tuple_list})
# ...
