From 9da6ed1a4297be9dbb8b9068c9e00837cbccf7a5 Mon Sep 17 00:00:00 2001 From: Tomas Cohen Arazi Date: Fri, 22 Jul 2022 17:42:35 -0300 Subject: [PATCH] Bug 31224: Add Koha::Biblio->metadata_record This patch introduces a higher-level method for retrieving a 'prepared' record for using in specific contexts. In particular, I only focused on embedding item information and OPAC view filtering. But we could add a way to get the record through the ViewPolicy also for staff. The virtue of this patch is that it explains better than my words why I think having the *embed_items* and *opac* parameters in Koha::Biblio::Metadata->record is not ideal. And makes the other implementation feel like is done at the wrong level. I know it's been done like that to act as a drop-in replacement fro GetMarcBiblio, which was a good first step. But we need to revisit how it is used, in general, to come up with a more refined and useful design. So we do not port the same design problems from C4::* into Koha::*. Try to think how it would be used in contexts like opac-MARCdetail.pl or any other OPAC controller script. Thanks!
