Difference between uses_versions/used_in_version and incoming_links/outgoing_links

[Remus Avram]

Hi Ftrack Team,

what exactly is the difference between uses_versions/used_in_version and incoming_links/outgoing_links attributes of Ftrack AssetVersion.

 

[Remus Avram]

incoming_links/outgoing_links are AssetVersionLink object type

and uses_versions/used_in_version  returns Collection of AssetVersion object type.

 

The thing that creates confusion is that when a new link between versions is created, incoming_links/outgoing_links attributes still return None. In order to get the incoming_links/outgoing_links we need to query again the session for the AssetVersion.

I found the documentation which explains the difference between them:

http://ftrack-python-api.rtd.ftrack.com/en/stable/example/entity_links.html

I was looking at the latest documentation which is a bit different

Yes, I agree this is confusing as we do not expire or update those relationships.
