ExtJS的4协会和store.save（） [英] ExtJS 4 associations and store.save()

问题描述

我使用ExtJS的4，并与定义关联的hasMany的典范。

I am using ExtJS 4, and have a model with an association hasMany defined.

ModelA -> hasMany -> ModelB

我用GridA显示来自MODELA数据。在点击GridA的记录，我用rowSelect事件创建GridB它们使用ModelA.ModelB（）作为存储。

I use GridA to show the data from ModelA. On clicking a record in GridA, I use a rowSelect event to create GridB which use ModelA.ModelB() as a store.

这一切都很好，直到我改变ModelB记录。该记录确实在层次结构得到更新，但是，当我执行StoreA.save（），不变更被发送回服务器。它没有注意到在关联的变化。如何保存这些数据，没有黑客的架构？

It all goes well until I change a record in ModelB. The record does get updated in the hierarchy, but when I execute StoreA.save(), no change is sent back to the server. It does not notice the changes in associations. How do I save this data, without hacking the architecture?

我期待的模型能够保存，正是它加载的方式。

I am expecting the Model to be able to save, exactly the way it loads.

此外，当我改变MODELA的记录，它被送回因为只有MODELA而不是ModelA-> ModelB，即使该记录有ModelB数据。

Also when I change a record in ModelA, it gets sent back as only ModelA and not as ModelA->ModelB, even when that record has ModelB data.

感谢

推荐答案

示范的关系没有得到很好的落实着呢，ExtJS的4.1不作出有关实施任何改进或者，以上几个重要的bug修复等。要了解更多信息请查看我的博客 HTTP：//blog.neolocus .COM / 2011/12 / ExtJS的-4和模型协会/

Model relations are not well implemented yet, and ExtJS 4.1 is not making any improvements on the implementation either, other than a few important bug fixes. To learn more check my blog at http://blog.neolocus.com/2011/12/extjs-4-and-model-associations/
