Each document version has unique noderef or not ?

anujsharma

I am using alfresco webscript to get the list of versions for a document

when i try to get the noderef of a all version using the property

child[i].noderef
as mentioned in below link:-
ScriptNode API | Alfresco Documentation

i get all versions node id as same

Please tell if the noderef is same for all versions

or if there is a way to get unique noderef of each version.

The nodeRef is the same because you are getting it from the document (children[i]) instead of the version.

Use docVersions[v].node.nodeRef instead

Update: Sorry - it was late and I got confused by your use of children[i] within the loop. Replaced children[i].node.nodeRef with docVersions[v].node.nodeRef

Each node in Alfresco and each version have a unique NodeRef. This is enforced on a DB constraint level and cannot be circumvented. Though there are features that masquerade the underlying NodeRef, e.g. when using multi-tenancy where it is technically possible for two tenants to have nodes with identical NodeRefs. But these identical NodeRefs are only identical on a logical level - in the underyling DB layer they are again unique.

Using js webscript how to get the unique noderef for each version of a document ?

The documentation on Script API for versions should help you get started...

Hi, Anuj
You can get the all versions of a document using this api url,
http://server ort/alfresco/service/api/version?nodeRef=workspace://SpacesStore/09d0c872-3f0a-49df-91f8-e1f8d8b257c1
You will get the output in JSON format.

hi,
i am able to get the documents versions .

My question is simply :- At DB level we are having unique noderef for a document version.

but when i do child[i].nodeRef , i get same noderef for all versions

is there some property other than 'noderef' which can give unique node reference.( i am referring to properties like in this documentation -------> ScriptNode API | Alfresco Documentation

Thanks

I seriously don't know what you are trying to access "child[i].nodeRef" for - and I don't know what values you have assigned to it. Via the ScriptNode getVersionHistory() operation you get a list of versions, and each version will have a "version.frozenStateNodeRef" property.

Use docVersions[v].node.nodeRef instead
