From a7d1c0e0ff7604114f2199e96e53027ecbc08f8c Mon Sep 17 00:00:00 2001 From: Tomas Cohen Arazi Date: Fri, 9 Jun 2023 15:42:23 -0300 Subject: [PATCH] Bug 33036: REST API: Merge biblio records implements merging of records + attached items, subscriptions etc via the API as an alternative to the web interface: cgi-bin/koha/cataloguing/merge.pl To Test: 1) you need an API user with the permissions "editcatalogue" 2) two records: one to be merged into (with biblio_id, eg 262) and another one from which to merge (with biblio_id_to_merge, eg 9) which will be deleted! both records may/should have items, subscription, subscriptionhistory, serial, suggestions orders and holds 3) check both records via the web 4) Apply patch 5) execute API calls eg like PUT /biblios/{biblio_id}/merge/{biblio_id_to_merge} eg: curl -s -u koha:koha -X PUT "http://127.0.0.1:8081/api/v1/biblios/262/merge/9" 6) the record with the id is deleted now, the record with has all items, etc attached, return code is 200, with the message {"message":"Successfuly merged 9 into 262"} 7) optionally a full MARCXML record may be sent as body of the API call curl -s -u koha:koha -X PUT "http://127.0.0.1:8081/api/v1/biblios/262/merge/2" -d @marcfile.xml 8) now also the content of the record with is replaced with the content of the MARCXML file 9) Sign off. 10) Thx Sponsored-by: Technische Hochschule Wildau Co-authored-by: domm@plix.at --- Koha/REST/V1/Biblios.pm | 98 +++++++++++++++++++++++++ api/v1/swagger/paths/biblios_merge.yaml | 48 ++++++++++++ api/v1/swagger/swagger.yaml | 2 + 3 files changed, 148 insertions(+) create mode 100644 api/v1/swagger/paths/biblios_merge.yaml diff --git a/Koha/REST/V1/Biblios.pm b/Koha/REST/V1/Biblios.pm index 6457d49d7a..afbbfb2fb0 100644 --- a/Koha/REST/V1/Biblios.pm +++ b/Koha/REST/V1/Biblios.pm @@ -25,6 +25,9 @@ use Koha::Ratings; use Koha::RecordProcessor; use C4::Biblio qw( DelBiblio AddBiblio ModBiblio ); use C4::Search qw( FindDuplicate ); +use C4::Serials qw( CountSubscriptionFromBiblionumber ); +use C4::Reserves qw( MergeHolds ); +use C4::Acquisition qw( ModOrder GetOrdersByBiblionumber ); use C4::Barcodes::ValueBuilder; use C4::Context; @@ -859,4 +862,99 @@ sub list { }; } +=head3 merge + +Controller function that handles merging two biblios.
