odoo 10.0 中的日期添加

Question

我有一个 class :

class DateAddition(models.Model):
      _name = "studentmanagement.dateaddition"

      input_date = fields.Date()
      output_date = fields.Date()
      no_months = fields.Integer()

然后如果我填写 input_date = "26 Feb 2017" 和 no_months = 2，output_date 将是 "26 April 2017"。 on_change 如何在 odoo-10.0 中做到这一点？

Answer 1

我不知道如何将它与您的 odoo on_change 挂钩，但这里有一个从日期字符串中添加或减去月份的例程：

代码：

import datetime as dt

def add_month(date, months):
    assert isinstance(date, dt.date)
    year, month, day = date.year, date.month, date.day
    year += int((month + months-1) / 12)
    month = (month + months - 1) % 12 + 1
    return dt.date(year, month, day)

def add_month_from_string(date_string, months):
    date = dt.datetime.strptime(date_string, '%d %b %Y')
    return add_month(date, months).strftime('%d %b %Y')

测试数据：

test_data = (
    ("26 Feb 2017", 2, "26 Apr 2017"),
    ("6 Dec 2016", 3, "6 Mar 2017"),
    ("26 Feb 2017", -2, "26 Dec 2016"),
)

for have, inc, want in test_data:
    print(have, inc, add_month_from_string(have, inc), want)

结果：

('26 Feb 2017', 2, '26 Apr 2017', '26 Apr 2017')
('6 Dec 2016', 3, '06 Mar 2017', '6 Mar 2017')
('26 Feb 2017', -2, '26 Dec 2016', '26 Dec 2016')
