python - 动态更改 fields.selection 选择

Question

Objective: Month field will show current month and previous month till 10th of current month, for 11th it will only show option of current month.

我已经寻找了类似问题的问题，并尝试了所有我能做的事情，所以这是我迄今为止尝试过的 -

.py

MONTH_LIST = [
    ('january','JANUARY'),
    ('february','FEBRUARY'),
    ('march','MARCH'),
    ('april','APRIL'),
    ('may','MAY'),
    ('june','JUNE'),
    ('july','JULY'),
    ('august','AUGUST'),
    ('september','SEPTEMBER'),
    ('october','OCTOBER'),
    ('november','NOVEMBER'),
    ('december','DECEMBER')
    ]


def _get_month(self, cr, uid, ids, field_name, arg, context=None):
        val = {}
        date_now = datetime.datetime.now()
        day = date_now.day
        month = date_now.month

        if day<10:
            val['month_val'] = MONTH_LIST[month-1][1] + MONTH_LIST[month-2][1]
        else:
            val['month_val'] = MONTH_LIST[month-1][1]

        return val


'month_val': fields.function(_get_month,  string='Month', type='selection', selection=MONTH_LIST, required=True),

遗憾的是，您无法在 Odoo 中执行此操作，选择的值是在 Odoo 启动时创建的，并且无法修改。一旦选择填满选择，就无法更改。尝试使用many2one，您可以动态更改域，即使使用many2one，如果您使用widget="selection"，您也会遇到问题域已更改您必须访问该字段两次才能看到列表已更改。
