Hi,
* upgrading CPSRelation results in broken (IOBTree, at least) graphs
Yes, sorry for that but the new products define completely new objects
with a new api, CPSRelation has been completely refactored so no
compatibility was kept.
* Is there a conversion guide available?
Unfortunately no. CPSComment was the only product actually using
CPSRelation, and it has never been packaged in a CPS release so we
assumed that nobody would want to change the products *and* keep
existing data.
It should be quite easy to export the Btrees content using the old
products, then replace by the new products, and then reimport data.
Please tell if you need guidance to do so, I would be glad if you could
make this contribution.
* RelationTool methods generally need the ManagePortal permission. E g.,
AFAIK,
relids = rtool.getRelationsFor(GRAPH_ID, docid, relation)
is now:
graph = rtool.getGraph(GRAPH_ID)
relids = graph.getSubjects(relation, docid)
But while getRelationsFor only needed the View permission, getGraph
needs ManagePortal
Yes, tool methods are no longer available, because it looked like an
unnecessary api duplication. If you really need access to the graph in
restricted code, I suggest you write the appropriate util methods to do so.
Are you using CPSRelation for a custom need? If so, I would be pleased
if you could explain your use case, see if the product addresses your
needs correctly.
I think the abstraction that is now available makes it a lot easier to
handle relations in CPS, I hope you will agree.
Regards,
