Python 2.7 打开时只读字段不写入数据库\u更改事件修改它
我已经将热度日和热度日设置为只读,所以用户不能直接修改它们 我有一个on_change事件,根据用户输入的其他字段修改它们 当用户输入当天的高、低温度时,度数日字段被正确修改;但是,当我单击“保存”按钮时,“度数日”字段将恢复为其原始值 我假设这是因为我在视图中将它们设置为只读 我认为必须有一种通用的方法来解决这个问题,但我在文档中找不到它 学位日Python 2.7 打开时只读字段不写入数据库\u更改事件修改它,python-2.7,openerp,Python 2.7,Openerp,我已经将热度日和热度日设置为只读,所以用户不能直接修改它们 我有一个on_change事件,根据用户输入的其他字段修改它们 当用户输入当天的高、低温度时,度数日字段被正确修改;但是,当我单击“保存”按钮时,“度数日”字段将恢复为其原始值 我假设这是因为我在视图中将它们设置为只读 我认为必须有一种通用的方法来解决这个问题,但我在文档中找不到它 学位日 from openerp.osv import osv, fields from dateutil.parser import * from dat

我添加了您建议的代码,并进行了一些编辑以消除语法错误(请参见上面的清单),但heat_degree_day和hw_degree_day的值仍然没有写入数据库。我甚至尝试在generate_degree_day结束时直接写入记录,但仍然不起作用。可能在到达此写入例程之前拦截了这些值……也许我需要从记录本身而不是从如果他们在VAL争论中…我会试试这个。
