From 4a7a0326ef031abb766495333c7e69d300169ae4 Mon Sep 17 00:00:00 2001 From: Tomas Cohen Arazi Date: Thu, 3 Dec 2020 15:11:14 -0300 Subject: [PATCH] Bug 24254: Add Koha::Items->filter_by_visible_in_opac This patch adds a method based on the original idea from Nick, but on Koha::Items. The idea is to build a proper filter, based on the current rules for hiding things, directly on the DBIC query. The caller takes care of knowing if the filtering should apply (i.e. checking the patron category exceptions) and then it would do something like: my @items; if ( ) { @items = $biblio->items->filter_by_visible_in_opac( { rules => $rules } ); } else { # still want to enforce 'hidelostitems' @items = $biblio->items->filter_by_visible_in_opac; } To test: 1. Apply this patches 2. Run: $ kshell k$ prove t/db_dependent/Koha/Items.t => SUCCESS: Tests pass! 3. Look at the use cases on the tests, read the code => SUCCESS: It all makes sense 4. Compare with Koha::Item->hidden_in_opac => SUCCESS: It all makes sense 5.
