Lookback API: Find all leaf node stories under a known parent
问题 In Rally Webservices API, if I want to traverse a Story hierarchy, it's necessary to do a query for the parent story, then grab the Children collection(s) off of the returned Stories, and then recursively query on each Child until the process reaches the Leaf node results. Question - is there a handy way to do this without iterating, by using a single query in the Lookback API? 回答1: This is one of the best features of the Lookback API. Let's say you have this hierarchy: Story 444 Story 555
