为什么我得到错误：'int'对象没有属性'create'？

Question

码：

 @api.multi
    def open_second_class(self):
        ac = self.env['ir.model.data'].xmlid_to_res_id('account.invoice_form', raise_if_not_found=True)
        write_obj = ac.create({'partner_id': self.name_id})
        accountant = False
        for o in self:
            accountant = o.id
        result = {
            'name': '2nd class',
            'view_type': 'form',
            'res_model': 'account.invoice',
            'res_id': write_obj.id,
            'view_id': False,
            'context': {'default_id_tbl1': accountant},
            'type': 'ir.actions.act_window',
            'view_mode': 'form',
            'target': 'new',
            'domain': '[]'
        }
        return result

错误：

使用self.env.ref('external_id')而不是xmlid_to_res_id方法。但我认为你想做的是这样的：

@api.multi
def open_second_class(self):
    self.ensure_one()
    ac = self.env.ref('account.invoice_form')
    invoice = self.env['account.invoice'].create({
        'partner_id': self.name_id.id
    })

    return {
        'name': '2nd class',
        'type': 'ir.actions.act_window',
        'res_model': 'account.invoice',
        'res_id': invoice.id,
        'view_type': 'form',
        'view_mode': 'form',
        'target': 'new',
        'context': {'default_id_tbl1': self.env.id },
    }
