这两个都能用作定时器，有什么不同？
有时候base.automation在Setting中用视图创建的也不会触发的？

在需要升级的模块中新增一个group，同时该模块的py中也要使用这个group计算某一个字段的值.

问题：升级模块的时候报错，找不到这个group对应的xml id

思考：
是加载顺序出错的，如果在加载py前加载了security的xml新增group的文件，那么加载py的时候就不会找不到xml id。

在__manifest__.py的data属性中加载的xml文件，是什么时候加载的？公共的xml文件（比如data，security中的），视图的xml文件，report的xml，wizard的xml文件，还有css，js，这些加载顺序是怎样的？

抛出警告本来就应该是一个简单的提示框。
你这个是报错的信息，你找找，在你抛出警告前就出错了。

就是类似弹框的那个，Confirm的方法可以自己写

得到的这3条数据用wizard展示，这样保存的方法方便自定义。仅供参考。

在执行报存操作的时候，偶尔会报这个错。只有在one2many字段中给某条记录选择父级的时候有这个错。有能解读下报错原因的吗？非常感谢。

@鲍永道 谢谢远程帮助。

原先 错误写法：

_renderView: function(){
            var _super = this._super.apply(this, arguments);
            ....
            return this._super();
        },

正确写法：

_renderView: function(){
            var result = this._super.apply(this, arguments);
            ....
            return result;
        },

原先的返回的就是错误的，this._super()不是父级返回。

那你在产品里面写好，这个订单行里面进行related
