From 2374462ad55265efea487eccb4939d5996b11871 Mon Sep 17 00:00:00 2001 From: Agustin Moyano Date: Fri, 9 Oct 2020 09:59:41 -0300 Subject: [PATCH] Bug 26635: Expand authorised values in to_api method This patch adds the posibility to expand authorised values when to_api method is called. The classes where authorised values should expand must implememnt the _fetch_authorised_values method, and must return a hash like the following { column_name => Koha::AuthorisedValue->unblessed ... } This patch will be used in bug 8179, so please test there.
