From a77c8a7cae34cc66b7e2f57f7ed4175af634f101 Mon Sep 17 00:00:00 2001 From: Kyle M Hall Date: Fri, 22 Aug 2014 13:29:28 -0400 Subject: [PATCH] Bug 12632 - Hold limits ignored for record level holds with item level itemtypes The crux of the issue is that if you are using item level itemtypes, but are allowing biblio levels holds, those holds do not have items. So, in CanItemBeReserved, when Koha counts the number of holds to compare against the given rule, it will always give 0 ( except of course for found holds, and the occasional item-level hold ). So the query is saying "link each of these reserves to the reserved item, and count the number of reserves this patron where the itemtype is DVD". However, since these are all record level reserves, there are no items to link to, and so when it looks for all reserves this and item whose itemtype is DVD, it finds zero reserves! This patch solves the problem by looking first at the item level itemtype, and if it does not exist, then it looks at the record level itemtype. For installations using record level itemtypes, the behavior remains unchanged. Test plan: 1) Enable item level itemtypes 2) Create two records with one item each of a given itemtype 3) Create a single issuing rule and limit the holds allowed for that itemtype to 1 4) Place a record level hold on your first record 5) Attempt to place a record level hold for the same patron on your second record. You should not be able to but you can! 6) Apply this patch 7) Repeat step 5, note you can no longer place the hold! --- C4/Reserves.pm | 10 ++++++++-- 1 files changed, 8 insertions(+), 2 deletions(-) diff --git a/C4/Reserves.pm b/C4/Reserves.pm index a98eed4..9f4c138 100644 --- a/C4/Reserves.pm +++ b/C4/Reserves.pm @@ -476,7 +476,6 @@ sub CanItemBeReserved{ my $borrower = C4::Members::GetMember('borrowernumber'=>$borrowernumber); my $controlbranch = C4::Context->preference('ReservesControlBranch'); - my $itemtypefield = C4::Context->preference('item-level_itypes') ?
