缺少1个必需的位置参数：odoo中的“self”？

Question

我正在尝试创建一个函数来发送一条消息给一个特定的用户，在我的模型中我写了这段代码

class SkypeBot(models.Model):
    _name = 'my.skype'
    _inherit = ['mail.thread', 'mail.activity', 'res.users']
    _description = 'My Skype'


    skype_login = fields.Char('Your skype Login')
    skype_password = fields.Char('Your skype password')
    skype_message = fields.Char(store=True)

    @api.multi
    def msg(self, message):

        partner_id = self.env['res.users'].search([('id', '=', 2)]).partner_id.id

        _logger.info('^^^^^' * 5)
        _logger.warning(partner_id)
        _logger.info('^^^^^' * 5)

        self.env['mail.message'].create({'message_type': 'notification',
                                         'subtype': self.env.ref('mail.mt_comment').id,  # subject type
                                         'body': message,
                                         'subject': 'Message subject',
                                         'partner_ids': [(4, partner_id), ],
                                         # partner to whom you send notification
                                         })

我想从另一个MySkype类调用此方法（msg）：

^{pr2}$

但是当这个方法被调用时，我得到了一个错误

我做错了什么？我该如何解决这个问题

我试着用@api.型号这对我没有帮助。 似乎我对odoo环境的初始化有问题，但我可以确切地知道在哪里

Answer 1

正如@TigerhawkT3所提到的，调用该方法就像它是一个静态方法，而不是一个类方法。在

In Python, the first argument of every class method (including init) is always a reference to the current instance of the class. By convention, this argument is always named self.¹

为了正确调用此方法，您需要创建类SkypeBot和的实例，然后调用msg()：

sbot = SkypeBot()
sbot.msg(message)

有关将self作为参数显式声明的语言设计决策的更多信息，请参阅this Stack Overflow post和{a2}撰写的这篇文章。在
