Topics loose their URI when updated

Reported by: jri Owned by: jri
Priority: Major Milestone: Release 4.2
Component: DeepaMehta Standard Distribution Version: 4.0.11
Keywords: Cc: dgf, Malte
Complexity: 3 Area:
Module: deepamehta-core


This happens when the URI is not contained in the update request (which is a still a valid request).

Solution: topic (and association) fields must *not* get default values in the respective model classes. Instead, possible dafault values must be set at the individual operation: an update operation must set *no* default values while a create operation has to.

Workaround: include the object's URI in the update request.

The workaround described in #536 is not applicable to Topicmaps.

Following a problem that I simply could not fetch my programmatically created Topicmap by URI the day later I had the suspicion that probably this issue has an effect there too. And through debugging I found out that Topicmaps currently always loose their URI as soon as they are in use (more specific: translated/panned).

E.g. The URI of the default topicmap "dm4.topicmaps.default_topicmap" is lost - not after I create a new topic in the topicmap but - after I translated the map once (which sends a PUT to the topimcap service).

Yes, you are right.
I will fix the URI problem for topicmaps within an hour.
(unfortunately the underlying real problem is not a quick fix)

Thanks, but I worked around that problem with loading my "Topicmap" via it's name.

And today, I have another problem to work with Topicmaps, IMO it would be better if you could check that in an hour (or so). I I can't (don't know how to) add "Topic" to a "Topicmap" programmatically. just finishing the report of that issue. Thank you very much.

Core fix: topics keep URI when updated (#311).

When updating a topic/association its URI is not lost.

See #311.
