From 6a2f1464d2674782fcac22d33fdc409ffcb47496 Mon Sep 17 00:00:00 2001 From: Martin Renvoize Date: Sun, 21 Sep 2025 16:07:34 +0100 Subject: [PATCH] Bug 19871: Move enum data truncation handling to centralized exception translation Complete the migration of enum data truncation exception handling from Koha::Object to the centralized ExceptionTranslator utility. This eliminates the last remaining manual DBIx::Class exception handling in Object code. Changes: - Add optional object parameter to ExceptionTranslator->translate_exception() - Update Schema wrapper methods to accept and pass object parameter - Enhance enum truncation handling to extract actual property values when object is available - Remove manual enum exception handling from Koha::Object::store() - Add comprehensive test coverage for enum handling with and without object context - Maintain contextual warning behavior for store() operations The centralized system now handles ALL DBIx::Class exception scenarios: - FK constraint failures (add/update and delete operations) - Duplicate key violations - Invalid data type values - Enum data truncation with actual property values This completes the centralization effort while providing better error reporting than the previous manual approach. --- Koha/Object.pm | 21 ++-------- Koha/Schema.pm | 8 ++-- Koha/Schema/Util/ExceptionTranslator.pm | 13 ++++-- .../Koha/Schema/Util/ExceptionTranslator.t | 41 ++++++++++++++++++- 4 files changed, 57 insertions(+), 26 deletions(-) diff --git a/Koha/Object.pm b/Koha/Object.pm index b35658411f2..be6834bef71 100644 --- a/Koha/Object.pm +++ b/Koha/Object.pm @@ -174,26 +174,11 @@ sub store { return $self->_result()->update_or_insert() ?
