Hello Claudia,I understand the both approaches, but in my opinion the "count" should mean "the number of items in a particular community" and not "the sum of items in subcommunities/collections of a particular community" even if the sum does not match
the distinct count...
Thank you for your reply. Fabian Smagghe Le 20/10/10 11:16, Claudia Jürgen a écrit :
Salut Fabian, having redundant counts has been discussed a while ago and been left as it is. Both approaches have disadvantages. If you do a distinct count then the user might be presented with lists where the sum of the subcommunities/collections does not fit the total in the community, which might be confusing. Maybe this should be made configurable in order to better fit the different use cases. Hope that helps Claudia Jürgen Am 20.10.2010 09:14, schrieb Fabian Smagghe:Hi, In function Community.countItems(), we made dso.countItems () for each collection and each subcommunity within: if some items are linked to several collections and/or subcommunities, these items are counted several times and the number of items in the Community is overvalued. In our repository, many items are linked to 2 collections (+- 20%). In function Community.countItems(), why not use a query like this (similar query used in function Collection.countItems()): query =" SELECT count(*) FROM communities2item, item WHERE " + "communities2item.community_id = ? " + "AND communities2item.item_id = item.item_id " + "AND in_archive ='1' AND item.withdrawn='0'"; Should this problem be reported in JIRA ?
