Question

Currently I have to make multiple GETs to receive all the information which I need

• User Story: FormattedID, _refObjectName, State, Owner._refObjectName
• Tasks for each User Story: FormattedID, _refObjectName, State, Owner._refObjectName
• Defect: FormattedID, _refObjectName, State, Owner._refObjectName
• Tasks for each Defect: FormattedID, _refObjectName, State, Owner._refObjectName

For all of the User Stories I use:

https://rally1.rallydev.com/slm/webservice/1.26/hierarchicalrequirement.js?query=((Project.Name = “[projectName]“) and (Iteration.Name = “[iterationName]“))&fetch=true&start=1&pagesize=100

For all of the Defects I use:

https://rally1.rallydev.com/slm/webservice/1.26/defects.js?query=((Project.Name = “[projectName]“) and (Iteration.Name = “[iterationName]“))&fetch=true&start=1&pagesize=100

Within each of these, if they have any Tasks, they display as:

{
  "_rallyAPIMajor": "1",
  "_rallyAPIMinor": "26",
  "_ref": "https://rally1.rallydev.com/slm/webservice/1.26/task/9872916743.js",
  "_refObjectName": "Update XYZ when ABC",
  "_type": "Task"
}

This doesn’t have all the information I need, so I hit each of the Tasks’ _ref URLs to get the full task information.

This adds up to sometimes 80+ AJAX calls per page load.

Is there a better query which would provide the extra Task information up front?

Answer 1

The fetch parameter can be tricky with queries. If you provide fetch=true you will get all of the fields that exist on the queried type (Story,Defect). If the field is also a domain object (like a tasks or a defect) you will only get the thin ref object like this

    {
       "_ref": "/task/1234.js"  
    }

If you want to get fields populated on the sub-objects you will need to specify the fields you want shown in the fetch param fetch=Name,FormattedID,Tasks. This would return an object like the one below:

{
      "HierarchicalRequirement" : {
        "Name" : "StoryName",
        "FormattedID" : "S1234",
        "Tasks" : [
          {
            "_rallyAPIMajor": "1",
            "_rallyAPIMinor": "26",
            "_ref": "https://rally1.rallydev.com/slm/webservice/1.26/task/9872916743.js",
            "_refObjectName": "Update XYZ when ABC",
            "_type": "Task",
            "FormattedID" : "T1",
            "Name" : "Update XYZ when ABC"
          }
        ]
      }
 }
                     

Let me know if that helped
