odoo-12 : 如何解决 write() 方法问题

Question

在我的情况下，我继承了 crm 表单并添加了一个 mamy2many 字段，此名称 [Estimation Assign to] 当我从该字段中选择用户并保存在添加关注者中添加所选用户并发送邮件的时间记录。现在的问题是，当我将看板卡从一个阶段更改为另一个阶段时，如果在表单估计字段中分配了一些用户，邮件也会发送这些用户。

但我只想在我打开记录并从估计字段中选择用户然后单击保存按钮时才发送邮件，我只想发送邮件。不是当我将看板卡从一个阶段更改为另一个阶段时。

如果你知道，请告诉我。

当estimation_id发生变化时，尝试添加另一个发送邮件的条件。

if u'estimation_id' in vals and rec.estimation_id:

编辑
以下代码将计算新添加的用户：

user_ids = {rec.id: [user_id.id for user_id in rec.estimation_id] for rec in self}
res = super(CrmLead, self).write(vals)
for rec in self:
    new_user_ids = [user.id for user in rec.estimation_id if user.id not in user_ids[rec.id]]
