extjs4 ajax api 商店更新

Question

在使用单元格编辑和网格面板中的组合框更新记录后，我尝试更新我的商店和数据库。 ajax 代理中的更新操作.action 正确触发，只是存储和网格不同步，并且 firebug 中的 post 选项卡显示我的 json 如下所示：“data []”。如何获取商店记录以创建 json 并更新记录？感谢您提前查看此内容...

为了正确更新你的ajax或rest调用必须返回一个包含更新记录的数组，即使它是一条记录，你也必须在一个数组中返回它，一个示例json响应（对于rest代理）应该像这样：

[{'id': 1, 'name': 'test', 'foo': 'bar'}]
