重写save_modle 方法，返回false 数据就不会保存到数据库，但是页面提示消息仍然提示保存成功，要如何修改

    def save_model(self, request, obj, form, change):
        oapi = OfficialApi()
        try:
            rankedwars_data = oapi.get_info('torn', 'rankedwars', obj.id)
        except ApiException as e:
            self.message_user(request, f'网络错误，未收到api的返回数据，请重试：{obj.id}, error：{e}', messages.ERROR)
            return False
        # 检查是否有rw_id有效性
        if rankedwars_data['rankedwars'].get(str(obj.id), None) is None:
            logger.error(f'rw_id错误,请检查，rw_id：{obj.id}')
            self.message_user(request, f'rw_id错误,请检查，rw_id：{obj.id}', messages.ERROR)
            # todo 能成功阻止数据保存，但是前端页面任然提示保存成功，需要修复
            return False
        # 选择帮派和rw_id不匹配
        if rankedwars_data['rankedwars'][str(obj.id)]['factions'].get(str(obj.faction_id.id), None) is None:
            logger.error(f'选择帮派和rw_id不匹配，rw_id：{obj.id}')
            self.message_user(request, f'选择帮派和rw_id不匹配，rw_id：{obj.id}', messages.ERROR)
            return False
        else:
            super().save_model(request, obj, form, change)
