尝试使用 Rally Java 工具包更新用户情景时出现"Could not update: Could not write changes in Unit Of Work"错误

Question

在尝试使用java工具包更新Rally中的userstory时:https://github.com/RallyTools/RallyRestToolkitForJava我使用以下代码获得"无法更新"错误。

RallyRestApi restApi = new RallyRestApi(new URI(RALLY_URI), RALLY_APIKEY);
restApi.setWsapiVersion("v2.0");JsonObject updatedDefect = new JsonObject();
updatedDefect.addProperty("c_ProdDeployDate", "20151405");
out.println(updatedDefect.getAsJsonObject());
UpdateRequest updateRequest = new UpdateRequest("https://us1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement/24091008142", updatedDefect.getAsJsonObject());
updateRequest.setFetch(new Fetch("Name", "c_buildlink", "c_ProdDeployDate"));
out.println(updateRequest.toUrl());
out.println(updateRequest.getBody());
UpdateResponse updateResponse = restApi.update(updateRequest);
out.println(Arrays.toString(updateResponse.getErrors()));
out.println(updateResponse.wasSuccessful());

输出如下:

{"c_ProdDeployDate":"20151405"}
/hierarchicalrequirement/24091008142.js?fetch=Name%2Cc_buildlink%2Cc_ProdDeployDate
{"hierarchicalrequirement":{"c_ProdDeployDate":"20151405"}}
[Could not update: Could not write changes in Unit Of Work]
false

基于这个问题:Rally webservices api v 1.36 无法更新:无法在Unit Of Work我试着通过curl来做这个，但是没有成功。

curl -X POST -v --header "zsessionid:_APIKEY_OMITTED" -H "Content-Type: application/json" -d "{"hierarchicalrequirement":{"c_ProdDeployDate":"20151405"}}" https://us1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement/24091008142 1>test.txt 2>test2.txt

用法:

{"OperationResult": {"_rallyAPIMajor": "2", "_rallyAPIMinor": "0", "Errors": ["Could not update: Could not write changes in Unit Of Work"], "Warnings": []}}

我找不到这个服务器错误的任何官方文档，所以我被什么是错的难住了。还要注意，我使用的apikey具有服务器写访问权限。

Answer 1

我在发布这篇文章后不久就发现了我的错误。虽然Rally没有返回关于日期格式的错误，但这就是问题所在。它将20151405视为有效的ISO8601日期，但不是Rally期望的特定形式，即"YYYY-MM-DD"。将行改为:

updatedDefect.addProperty("c_ProdDeployDate", "2015-14-05");
