Answer 1

您的 write 方法应该在字典数据结构中传递字段值，例如

write({'is_art_approved', True})

而不是像这样传递它：

write('is_art_approved', True)

在写入方法中ids 是必需的参数，但这取决于代码的编写方式。更多关于写方法的是here

最佳，

Answer 2

odoo 中的

create 或write 方法需要将数据的字典（键：值对） 写入数据库。从您的错误代码中，它显示了错误调用的 write 方法。应该是这样的：

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

其中ids 是您需要更新数据库中数据的记录ID。

Answer 3

您忘记了一些参数或使用了太多参数。 write 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
