I need to get all the parent hierarchy from a work item.

The parent of the parent of the parent.. find all the parent links.

There is a way to do it via API?

Thanks :)

CodePudding user response：

Yes, you can.

But you must use code to handle this situation. The below is a Python demo.

from azure.devops.connection import Connection
from msrest.authentication import BasicAuthentication

#get all the work items linked to a work item
def get_work_items_parents(Organization_Name, personal_access_token, wi_id):
    #get a connection to Azure DevOps
    organization_url = 'https://dev.azure.com/' Organization_Name
    credentials = BasicAuthentication('', personal_access_token)
    connection = Connection(base_url=organization_url, creds=credentials)
    work_item_tracking_client = connection.clients.get_work_item_tracking_client()
    work_item = work_item_tracking_client.get_work_item(wi_id, expand="relations")
    #get the work item links
    for item in work_item.relations:
        #get parent and child work items
        if item.attributes['name'] == 'Parent':
            #get the work item id
            work_item_id = item.url.split('/')[-1]
            #get the work item
            linked_work_item = work_item_tracking_client.get_work_item(work_item_id)

            #add the work item to the list
            work_items_parents.append(linked_work_item)
            #get the parents of the parent
            get_work_items_parents(Organization_Name, personal_access_token, work_item_id)
    return work_items_parents


personal_access_token = 'xxx'
Organization_Name = 'xxx'
workitem_id = 120
#create a list
work_items_parents = []

items = get_work_items_parents(Organization_Name, personal_access_token, workitem_id)

for item in items:
    print(item.fields['System.Title'])

I can successfully get all parents of workitem id '120':

The above is the API of Python SDK Demo, if you want to use REST API, I can also give you an idea.

Just call this REST API:

https://dev.azure.com/<Organization Name>/<Project Name>/_apis/wit/workitems/<Workitem ID>?api-version=6.0&$expand=relations

You can call it again after getting the current parent:
