Odoo，Python:ValueError:write（）为关键字参数'；上下文'；

测试模块时出现此错误

我正在尝试对销售订单进行两级验证 确认未经批准的订单将无法完成 由sales managaer group发送，因此此按钮发送电子邮件、打印、确认将不会显示，而不显示approve first

提前感谢

您的写入方法应该传递字典数据结构中的字段值，如

write({'is_art_approved', True})

而不是像这样传递它：

write('is_art_approved', True)

在写方法中，

ids

是必需的参数，但这取决于代码的编写方式。有关写入方法的更多信息，请参阅

---

最好的是，odoo中的

创建

或写入方法需要在数据库中写入数据的字典（键：值对）。从错误代码中，它显示了错误调用的write方法。其内容应如下：

obj.write(cr, uid, ids, {'key':'value'}, context=<<your context>>)

obj.write（cr，uid，id，{'key'：'value'}，context=）

---

其中，

id

是需要更新数据库中数据的记录id。

您忘记了一些参数或使用了太多参数。 写入方法应包含以下参数：

 cr #used database cursor
 uid #logged in user
 ids #id from the object youŕe writing to
 data #dictionary of data that has to be written
 context #the given context

---

代码似乎不完整，您是否也可以包含您的业务逻辑。请添加完整的错误回溯。在您面临错误的位置发布全部代码。添加请检查帖子

 cr #used database cursor
 uid #logged in user
 ids #id from the object youŕe writing to
 data #dictionary of data that has to be written
 context #the given context
