REST API > link between nodes and processes

JC83 — Wed, 12 Jan 2022 13:34:55 GMT

Hello,

Thanks to the API I'm now able to list all the nodes and all the processes ..

but I can't find any link between those 2 entities ..

How could I find the processes associated with a given node ?

How could I find the associated node of a given process ?

Thanks !

Processes are composed of Tasks. Tasks are associated to documents.

You need to find a task on a process and to use the "items" REST API.

For instance, for task 79...

http://127.0.0.1:8080/alfresco/api/-default-/public/workflow/versions/1/tasks/79/items

        "entry": {
          "createdAt": "2022-01-12T13:42:55.268+0000",
          "size": 107376,
          "createdBy": "admin",
          "modifiedAt": "2022-01-12T13:42:56.389+0000",
          "name": "from-ecm-to-content-services.pdf",
          "modifiedBy": "admin",
          "id": "2e53740f-5bef-442b-8319-1e7150341318",
          "mimeType": "application/pdf"
        }

... there is one document associated with located in workspace://SpacesStore/2e53740f-5bef-442b-8319-1e7150341318

thanks !

I cannot find any tasks of completed processes ..

I don't see any filter in ../processes/id/tasks allowing to show "completed" tasks ..

Another question : what if we have several version of the document. How can I see the version which was concerned but a given process ?

Once a process has been completed, you need to use the process API, since there is no "live" task.

For instance, for process 33:

http://127.0.0.1:8080/alfresco/api/-default-/public/workflow/versions/1/processes/33/items

I guess there is no direct invocation to get the version used for that task / process. You need to calculate that from dates and version REST API.

thanks ..

Ok .. it's nearly done ..

I try to compare process endedDate with version "modifiedAt" date ...

Is this the right comparison to do ?

It seems not

Here 3 versions .. I cannot know the one to choose ..

Completed #1084545 on value: Progress Report # 12 v1.2.docx (nodeRef=679a519e-3cc4-481d-8e87-c1d8638034b8) by JB221813 type=validationHierarchique:159:1072212
process end date = 2022-01-10T09:45:09.000+0000

v1.0 @ 2021-11-16T15:05:11.080+0000 diff=-4732798(s)

When there is only one version, thoses date are not the same..
