[ckan-dev] Deleting revisions & 'current' flag

Tue Jul 17 12:47:55 UTC 2012

John & other CKAN devs,

I think our CKAN database is getting confused by deleted group
memberships. For example I have a dataset whose membership of a group
was deleted (and maybe some other operations by the user) but when
CKAN indexes the dataset (i.e. package_show), it still thinks it is in
the group. I'm wondering if the 'current' column of the revision table
was ever tested with deleted objects?

I'm a bit hazy on this part of the model, so I've copied below the
table in question. There seems to be two 'current' revisions, which
seems wrong to me. Can you confirm if this is wrong, or have I missed
something?

select revision_timestamp, expired_timestamp, current, state  from
member_revision where table_id =
'1cfcf936-5b1b-4726-9930-0fe004aab27d' and group_id =
'036abab4-15ed-485a-8e14-9a599ea1619e' order by revision_timestamp
asc;

     revision_timestamp     |     expired_timestamp      | current |  state
