Python Odoo-用新api覆盖旧api方法？

我试图覆盖

compute\u return

方法，但出现了一个错误。我用错装饰器了吗？（尝试过，

模型

，

多个

和

一个

，但每一个都给出了一个错误）。 例如，这样做：

@api.model
def compute_refund(mode='refund'):
    inv_ids = self.env.context.get('active_ids', [])
    for invoice in self.env['account.invoice'].browse(inv_ids):
        if invoice.employee_invoice:
            if mode == 'refund':
                raise Warning(_("This Refund Method is not supported for employee invoices"))
            if mode == 'cancel':
                #Unrelate such invoice from insurance.commission.payment record
                invoice.commission_payment_id = None
                for line in invoice.invoice_line:
                    line.insurance_commission_ids.write({'state': 'confirm'})
                    line.insurance_commission_ids = None
    return super(account_invoice_refund, self).compute_refund(mode=mode)

但在尝试运行该方法时，它只会出现以下错误：

我想得太深了。我犯的错误是，在定义方法时，我只是忘记添加

self

参数。我还不能投票，因为我的标点符号，但答案1对我来说很有用，我只是想恭维一下，如果你不使用@api来装饰，当你用新api设置一个按钮时也会出现这种情况。multi它会因这个错误而失败，我希望它能帮助其他人知道它是解决这个错误的方法

用@api.multi装饰 和 使用self将方法附加到类

@api.multi
def your_method(self):
    -...- Do your stuff.

即使这个问题已经得到了回答，我还是想说将

@api.model

更改为

@api.multi

也有助于返回视图。我搜索了几个小时，终于解决了我的问题！ 以下是我的工作代码示例：

@api.multi
def action_button_return_view(self):
    view_id = self.env.ref('external_id').id
    return {
        'name': 'Name',
        'view_type': 'form',
        'view_mode': 'tree',
        'view_id': view_id,
        'res.model': 'your_model',
        'type': 'ir.actions.act_window',
        'target': 'current'
    }
