https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=21674 --- Comment #12 from Nick Clemens <nick@bywatersolutions.com> --- Created attachment 97838 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=97838&action=edit Bug 21674: Prevent to insert twice the same library in a group You can create hierarchical groups of libraries you are not allowed to add several times the same library to a given group/subgroup. The libraries that are part of the group is not displayed on the interface, to prevent the user to select it. However this restriction is only done template-side, the controller and module does not handle it. To prevent that this patchset enforces the constraint at DB level, and display a message to the end user. Test plan: - Go to Home › Administration › Library groups - Add a group - Add a library - reload the page several times => Without this patch the same library appears several times in the group => With this patch applied you will see a friendly error message Signed-off-by: Nick Clemens <nick@bywatersolutions.com> -- You are receiving this mail because: You are watching all bug changes.
