REST API Update WorkItemHierarchyLink

Task 1234 has parent Task 5678.  I want to change Task 1234 parent to Task ABCD.

I am attempting to do this:

* using a push of a WorkItemHierarchyLink with a new parent and child set using the ID I find with a query.

* deleting the existing WIHL entity and creating a new one.

Thanks for the quick response Jacob.

Can you please share the requests you are sending so I can try to reproduce your issue?

curl -H "Authorization: Session XXXXX" https://api2.clarizen.com/v2.0/services/data/objects/WorkItemHierarchyLink/YYYYY -d "{child: '/Task/AAAA', parent: '/Task/BBBB'}"

And the results:

{"errorCode":"InvalidOperation","message":"Invalid operation: Field 'Child' can only be updated when the entity is created.","referenceId":"13xHw84Q9w0nNJa1Ev8Zoj"}

The other complains on the delete based on what I think is custom validation in our setup so I haven't done it.

[General] Task 'TASK NAME' cannot be converted to a to do list item because it has one or more children or it being use as a shortcut in a project is the other error I'm getting.

Hi Jacob,

I did some research and I think that this action will not give you the results you want.

To make the scenario clear and simple, are you trying to move work items from one parent to the other?

Elad, that's exactly it.

Hi Jacob,

If this is the scenario you can use the objects endpoint (https://api2.clarizen.com/V2.0/services/data/objects), POST method, to update the parent field.

For example:

URL:https://api2.clarizen.com/V2.0/services/data/objects/Project/xxxx-xxxx-xxxx-xxxx

Method:POST

Body:

{
         'Parent':'/Project/5fcaf951-f432-417c-96b1-c406132afdf9_1'
}

This will change the xxxx project's parent.

I hope this helps,

Elad

Getting an error message back attempting to change the parent of a task:

[InvalidOperation] Invalid operation: Field 'Parent' can only be updated when the entity is created. (Reference Id: R3mJTm4HCKZZan54lGXrS)

Ideas?

Hi Jacob,

I found the solution, in a case you want to change the parent of a work item you need to delete the existing RealWorkItemHierarchyLink and create a new one.

For example:

Method:DELETE 

URL: data/objects/RealWorkItemHierarchyLink/5g58xe2k4lumipju7uf6uz5ht2

and then create the new RealWorkItemHierarchyLink :

Method: PUT

URL: data/objects/RealWorkItemHierarchyLink

Body:

{
   "Child": "/Project/9i6ydsvjmta9qrzffhj2i4m511",
   "Parent": "/Project/9i6ydsvjmta9qrzffhj2i4m50"
}

I hope this will solve your problem

When doing that I am getting:

Elad, could I please have an update. This seems like something else in the API that is not feature complete (along with URL fields and being able to specify the text instead of just the URL).  Can you confirm the soap could handle this? I would hate to mix both, but if that's the only option...

Hi Jacob,

Sorry for the late response. It is not an issue with the REST API. I did my research on projects and I missed that you are working with tasks. You are trying to move a Task that probably has child work items or it is a shortcut. I am still researching if this action is available via the API.

I will keep you up to date.

Hi Jacob,

After many tries it seems like it is not supported in the API. The task link to the project cannot be deleted as the Task has child items.

I will continue to find a solution and I will update here if I find one.
