Issue/Introduction

When I use a deprecated version of WS API (anything prior to v2.0) I can get elements of collections from the same request, but now I only get a reference object of the collection, and have to make a separate request to load the collection elements.

Environment

Release: AGUE5099000-SAAS-Agile Central-Unlimited Edition SaaS-50 User Pack
Component:

Resolution

In v2.0 of Web Services API collections are not hydrated automatically. Tasks on a User Story, Defects on a User Story, UserStories on a Feature, Iterations on a Project, etc. are examples of collections. For performance reasons v2.0 (unlike its predecessors - please see the API deprecation schedule here) does not allow getting the elements of the collection from the same request you made to get the parent object. You need a second request to load (hydrate) the collection. 

However v2.0 has a concept of collection's summary. See WS API documentation for Collections.

EXAMPLE 1: Iterations collection on Project

Here is an example of an endpoint that fetches Iterations collection on Project without summarizing it:

https://rally1.rallydev.com/slm/webservice/v2.0/projects?fetch=Name,Iterations

Notice that even if fetch includes StartDate and EndDate, as in ?fetch=Name,Iterations,StarDate,EndDate those Iteration fields will not be included in the result. The iteration object returned by this endpoint is only a reference to the full object:
 


To summarize the collection by a desired fields, follow this syntax:

https://rally1.rallydev.com/slm/webservice/v2.0/projects?fetch=Name,Iterations:summary[StartDate;EndDate]

Notice Iterations:summary format: ?fetch=Name,Iterations:summary[StartDate;EndDate]

The iteration object returned by this endpoint includes StartDate and EndDate fields.

EXAMPLE 2: TestCases collection on HierarchicalRequirement

Here is an example of an endpoint that fetches TestCases collection on User Stories without summarizing it. User Stories are filtered by iteration:

https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?workspace=https://rally1.rallydev.com/slm/webservice/v2.0/workspace/12352608129&query=(Iteration = /iteration/40695561076)&fetch=TestCases&pagesize=200

The same endpoint where TestCases are summarized by LastVerdict attribute of TestCase object:

https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?workspace=https://rally1.rallydev.com/slm/webservice/v2.0/workspace/12352608129&query=(Iteration = /iteration/40695561076)&fetch=TestCases:summary[LastVerdict]&pagesize=200

Here one of the stories scheduled for this iteration, a story "abc" has 3 test cases in its TestCases collection. Two of them have LastVerdict "Pass". The third test case does not have a verdict, hence "No Entry".


The query above can be modified to include a summary of TestCases by FormattedID in addition to LastVerdict

https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?workspace=https://rally1.rallydev.com/slm/webservice/v2.0/workspace/12352608129&query=(Iteration = /iteration/40695561076)&fetch=TestCases:summary[FormattedID;LastVerdict]&pagesize=200
 

  • Summary:
     
    {
    • TestCases:
       
      {
      • LastVerdict:
         
        {
        • -- No Entry --: 1,
        • Pass: 2
        },
      • FormattedID:
         
        {
        • TC1160: 1,
        • TC1158: 1,
        • TC1159: 1
        },
      • Count: 3
      }
    },
