https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=17246 --- Comment #1 from Jonathan Druart <jonathan.druart@bugs.koha-community.org> --- Created attachment 55166 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=55166&action=edit Bug 17246: Do no support arrayref to define multiple FK Currently you can call GetPreparedLetter like: $prepared_letter = GetPreparedLetter( ( module => 'test', letter_code => 'TEST_HOLD', tables => { reserves => [ $fk1, $fk2 ], }, ) ); It assumes that $fk1 is a borrowernumber and $fk2 a biblionumber. It seems hazardous to do this guess. I suggest to remove this feature and only allow hashref indeed. Test plan: Use different way to generate letters and make sure you do not reach the croak -- You are receiving this mail because: You are watching all bug changes.
