From 2036c3fd2d0833849acaeb410805a1c357dda483 Mon Sep 17 00:00:00 2001 From: Tomas Cohen Arazi Date: Fri, 27 Mar 2020 16:38:15 -0300 Subject: [PATCH] Bug 25006: Make Koha::Item->as_marc_field skip undefined subfields This patch makes as_marc_field skip subfields that don't have a value or contains an empty string (replicating C4::Items:1021 logic). To test: 1. Apply the regression tests patch 2. Run: $ kshell k$ prove t/db_dependent/Koha/Item.t => FAIL: Tests fail because the generated MARC::Field contains undef subfields. 3. Apply this patch 4. Repeat 2. => SUCCESS: Tests pass! Undefined and empty subfields are skipped! 5.
