在odoo中引发异常时将日期字段设置为空

from odoo import models, fields

class MyModel(models.Model):
    _name = 'my.model'

    date_field = fields.Date(string='Date')

    def some_method(self):
        try:
            # Some code that may raise an exception
            pass
        except Exception as e:
            # Exception handling code
            self.date_field = False
