feat(workitems): Add Children field to WorkItem struct.

Florian Forsterrequested to merge
fforster/children into main

What does this MR do?

Adds support for a work item's child items to WorkItemsService, and refactors the shared GraphQL parent/linked-item unwrapping logic that this feature builds on.

workItemIIDGQL extraction (cleanup)

Adds a shared workItemIIDGQL type with an unwrap() method that parses the GraphQL iid/namespace.fullPath pair into a WorkItemIID. This replaces the duplicated anonymous parent/workItem structs previously defined inline in workItemWidgetHierarchyGQL and workItemWidgetLinkedItemsGQL, and simplifies workItemWidgetLinkedItemsGQL.unwrap() by delegating IID/namespace parsing to workItem.unwrap() instead of parsing manually.

workItemWidgetHierarchyGQL.unwrap is renamed to unwrapParent, to free up the name for the new children logic below.

Children support (feature)

Adds a Children []WorkItemIID field to WorkItem, populated from the hierarchy widget's hasChildren/children fields — mirroring the existing Parent support. Adds workItemWidgetHierarchyGQL.unwrapChildren(), which returns nil when HasChildren is false and otherwise maps each child node through workItemIIDGQL.unwrap().

Extends the hierarchy widget selection in workItemTemplate and in the get_workitem, list_work_items, create_work_item, and update_work_item GraphQL test fixtures with hasChildren and children { nodes { iid namespace { fullPath } } }.

Testing

  • Updated testdata/get_workitem.json with a sample child work item
  • Updated TestGetWorkItem_SuccessfulResponse to assert Children is populated correctly
