前言

在日常中有很多审批场景，例如请销假。审批拒绝的时候应该给出原因，此时，在form界面点击拒绝的时候应该弹出输入窗口。如下图所示。

编写模型
模块的目录下，新建wizard文件夹，然后直接创建一个models.py和views.py
参考代码如下：

class RejectReasonWizard(models.TransientModel):
    _name = 'reject.reason.wizard'

    vehicle_id = fields.Many2one('vehicle', string='车辆')
    reason = fields.Text(string='拒绝原因')

    def action_confirm(self):
        self.vehicle_id.write({
            'status': 'rejected',
            'reason_for_rejection': self.reason,
            'approval_time': fields.Datetime.now(),
            'approver': self.env.user.name + '-' + self.env.user.login,
            'qrcode': g_qrcode(self.vehicle_id.id),  # 生成二维码
        })
        return {'type': 'ir.actions.act_window_close'}
