Question

我正在尝试覆盖 compute_refund 方法，但出现错误。我使用了错误的装饰器吗？（尝试过 model、multi 和 one，但每一个都会出错）。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)

但是在尝试运行方法时它只是给出了这个错误：

Answer 1

我想得太深了。我犯的错误是我在定义方法时忘记添加 self 参数。并且需要 multi 装饰器。

Answer 2

我还不能投票，因为我的标点符号，但答案 1 对我有用，我只是想称赞当你用新 api 设置按钮时，如果你不使用 @[ 装饰，它也会发生=15=] 它会因这个错误而失败，我希望它能帮助其他人知道这是解决这个错误的方法。

用@装饰api.multi 和使用 self.

将方法附加到 class

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

Answer 3

即使问题已经得到解答，我想说的是，将 @api.model 更改为 @api.multi 也有助于返回视图。我搜索了几个小时，这终于解决了我的问题！这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'
    }
