From 755d82015d78d4d0c8d33770e93db9bdd63cd587 Mon Sep 17 00:00:00 2001 From: Agustin Moyano Date: Fri, 24 Jan 2020 23:59:32 -0300 Subject: [PATCH] Bug 24502: object.search also filter by prefetched columns This patch adds the possibility to object.search helper, to also filter by prefetched columns. In order to dynamically add filter parameters, they must be coded as json and placed in the body of the request, coded as string in 'q' query parameter or as string in 'x-koha-query' header. The coded json, is in fact dbix syntax. To test: 1. apply this patch 2. prove t/Koha/REST/Plugin/Query.t t/db_dependent/Koha/REST/Plugin/Objects.t 3.
