Question

这是我关于setting a default date in create form的问题的第二步，我在这里提出澄清两个问题：

我的任务还包括将requested_date字段设置为星期一，如果它最初是在星期六或星期日设置的，那么我在_defaults中使用“isoweekday”方法设置了条件，但似乎_defaults没有支持条件：

_defaults = {
    'requested_date': (date.today() + timedelta(days=28)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    if requested_date.isoweekday = 6
        'requested_date': (date.today() + timedelta(days=30)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    if requested_date.isoweekday = 7
        'requested_date': (date.today() + timedelta(days=29)).strftime(DEFAULT_SERVER_DATE_FORMAT),
}

计算机终端告诉我语法无效，我使用“if”，这是我第一次使用条件，所以也许我只是没有像我一样写它们。

这是我得到的完整信息：

Answer 1

对于那些想知道的人，对于我的问题的第二部分（避免requested_date在周末），我已经写了这个函数，它似乎有效（至少它仍然显示了28天后的日期）创建），我没有办法测试它，但至少我没有错误，当我用这个更新数据库或当我尝试创建此字段所在的表单时：

def _set_requested_date(self, cr, uid, ids, context=None):
    requested_date = (date.today() + timedelta(days=28)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    day = date.today()
    if day.isoweekday() == 6:
        requested_date = (date.today() + timedelta(days=30)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    if day.isoweekday() == 7:
        requested_date = (date.today() + timedelta(days=29)).strftime(DEFAULT_SERVER_DATE_FORMAT),
    return requested_date

_defaults = {
    'requested_date': _set_requested_date,
}
