我一直在尝试查询Rally只是为了通过ObjectID获取某个对象,但在很多情况下我最终需要它的父对象。例如,对于任务,我需要其关联的用户故事和故事的功能。它最终成为一连串的回调(公平警告,它很丑陋) - 任何人都可以推荐更有效的解决方案吗?通过OID查询的能力很好,但是它太糟糕了,我需要的不仅仅是关于该OID的信息。 (注意 - 解决方案必须使用WSAPI,而不是LBAPI)。
Rally.data.WsapiModelFactory.getModel({
type: 'Task',
context: {
workspace: Rally.util.Ref.getRelativeUri()
},
success: function(taskModel) {
taskModel.load(oid, {
scope: this,
callback: function(taskRecord, op, success) {
if (taskRecord && taskRecord.data.WorkProduct && taskRecord.data.WorkProduct._type == "HierarchicalRequirement") {
// get User Story
Rally.data.WsapiModelFactory.getModel({
type: 'User Story',
context: {
workspace: Rally.util.Ref.getRelativeUri()
},
success: function(userStoryModel) {
userStoryModel.load(taskRecord.data.WorkProduct._ref, {
scope: this,
callback: function(storyRecord, op, success) {
if (storyRecord && storyRecord.data && storyRecord.data.Feature) {
// Get Feature
Rally.data.WsapiModelFactory.getModel({
type: 'PortfolioItem/Feature',
context: {
workspace: Rally.util.Ref.getRelativeUri()
},
success: function(featureModel) {
featureModel.load(storyRecord.data.Feature._ref, {
scope: this,
callback: function(featureRecord) {
displayTask(oid, taskRecord, storyRecord, featureRecord);
}
});
}
});
}
}
});
}
});
}
}
});
}
});

您可以直接在单个查询中提取“工作产品”父级及其关联的功能。试试这个:
Ext.create('Rally.data.WsapiDataStore', {
model : 'Task',
fetch : ['WorkProduct','Name','Feature'],
filters : [{
property : 'ObjectID',
value : OID
}]
}).load({
callback : function(records, operation, success) {
var task = records[0];
var userStory = task.get('WorkProduct');
var feature = userStory.Feature;
}
});
