@hanayo 在 @api.depends 可以返回错误信息吗 中说：

ValidationError

请问返回ValidationError 后， form可以继续提交吗
我想在报错后， 不让表单提交 ， 直至用户正确填写字段后才能提交form

价格表是产品计价策略。
比如你可以为渠道经销商设置不同级别折扣。
也可以指定某类商品设定不同折扣标准。这个折扣可以指定有效日期期间，比如季节性的促销；也可以指定不同的地区，当客户来自不同的地区则会自动匹配对应的价格折扣标准。

产品的销售价格的计算标准可以基于产品上的统一标准售价，也可以根据进价按照利润率加价形成销售价格，也可以基于另外的价格表。

@鲍永道 不太明白，能详细说明吗

忙了一整天。。。

@hui 多多交流。

@张优秀iii odoo的前端写法，扩展，源码里面也有很多参考写法。

试图中用id做表达式，但是试图中却没有这个字段。应该加上并隐藏

@hui 我已经找到了源码中的处理方式， 用onchange方法监听product_id的变化， 从而改变相应列的值

不懂。也极不习惯“大佬”，特此留言。

我刚才打断点进常规设置看了一下，定位到 res_config_settings这个model，你可以去看看你是不是少了这个字段

@las_aves不用客气，多交流。15068334016也可以加微信聊。
