From 4773dd469c1cf168fa9d5907ae125633274da131 Mon Sep 17 00:00:00 2001 From: Kyle M Hall Date: Wed, 8 Sep 2021 11:59:25 -0400 Subject: [PATCH] Bug 28974: Add pagination to holds queue viewer We have a partner processing thousands of holds per day, per branch. At this number of holds, the script loads very slow if it manages to load at all. Paginating the results of the holds queue will allow this page more flexible and load more quickly. Test Plan 1) Generate a lot of holds in the holds queue 2) Apply this patch 3) Try out the new pagination bar 4) Ensure the limit and page features function correctly Signed-off-by: Emmi Takkinen --- C4/HoldsQueue.pm | 30 ++++++++++++++++++- circ/view_holdsqueue.pl | 28 ++++++++++++++--- .../prog/en/modules/circ/view_holdsqueue.tt | 27 +++++++++++++++++ t/db_dependent/HoldsQueue.t | 2 +- 4 files changed, 81 insertions(+), 6 deletions(-) diff --git a/C4/HoldsQueue.pm b/C4/HoldsQueue.pm index bc8df7060e..5a06ac5421 100644 --- a/C4/HoldsQueue.pm +++ b/C4/HoldsQueue.pm @@ -132,6 +132,11 @@ sub GetHoldsQueueItems { my $params = shift; my $dbh = C4::Context->dbh; + my $limit = $params->{limit} || 20; + my $page = $params->{page} || 1; + + my $offset = 0 + ( $limit * ( $page - 1 ) ); + my @bind_params = (); my $query = q/SELECT borrowers.surname, borrowers.othernames, @@ -169,6 +174,7 @@ sub GetHoldsQueueItems { push @bind_params, $params->{locationslimit}; } $query .= " ORDER BY ccode, location, cn_sort, author, title, pickbranch, reservedate"; + $query .= " LIMIT $limit OFFSET $offset"; my $sth = $dbh->prepare($query); $sth->execute(@bind_params); my $items = []; @@ -190,7 +196,29 @@ sub GetHoldsQueueItems { push @$items, $row; } - return $items; + + @bind_params = (); + my $total_query = "SELECT COUNT(*) FROM tmp_holdsqueue JOIN items USING (itemnumber) WHERE 1=1 "; + if ($params->{branchlimit}) { + $total_query .=" AND tmp_holdsqueue.holdingbranch = ?"; + push @bind_params, $params->{branchlimit}; + } + if( $params->{itemtypeslimit} ) { + $total_query .=" AND items.itype = ?
