Iteration.StartDate 不可用

Question

当我使用 Rally.data.WsapiDataStore 查询用户故事时，我可以检索 Iteration.StartDate 和 Iteration.EndDate。但是，当我使用 .getCollection('Predecessors') 加载集合时，加载了迭代名称，但未填充 StartDate 和 EndDate。应用程序代码写入控制台以检查 Iteration 对象。

Answer 1

我好像记得这是 2.0rc3 版本中 getCollection 方法的一个错误。如果您在 config 参数中传递 fetch 而不是将其传递给 load 会怎么样？

userStory.getCollection('Predecessors', {
    fetch: ['Iteration', 'StartDate', 'EndDate', etc...]
}).load()...

您也可以尝试升级到更新的 SDK 版本 - 2.0 或最新的 2.1...

Answer 2

我很困惑，您是希望填充 fetch[] 中定义的 "StartDate" 和 "EndDate" 字段，还是希望填充 Iteration.EndDate 和 Iteration.StartDate 被填充。第一个不存在于用户故事中（这是 getCollection 将要 return 的类型），它们仅存在于 Iteration 类型中。

我认为 KyleM 指的是为一种类型获取的默认字段，除非您用另一个列表覆盖该列表 - 当获取的项目是 getCollection 的一部分时我不确定该怎么做（这将采用您指定的配置，而不是将其传递给迭代数据的提取）

Iteration.StartDate 不可用

Iteration.StartDate not available
