Each log entry includes the number of the user currently logged in. For batch jobs, which operate without authenticating a user and setting up a session, the user number is set to 0, which is the same as the superlibrarian's number. =cut #' sub logaction { my ($modulename, $actionname, $objectnumber, $infos, $interface)=@_; # Get ID of logged in user. if called from a batch job, # no user session exists and C4::Context->userenv() returns # the scalar '0'. my $userenv = C4::Context->userenv(); my $usernumber = (ref($userenv) eq 'HASH') ? $userenv->{'number'} : 0; $usernumber ||= 0; $interface //= C4::Context->interface; if( blessed($infos) && $infos->isa('Koha::Object') ) { $infos = $infos->get_from_storage if $infos->in_storage; local $Data::Dumper::Sortkeys = 1; if ( $infos->isa('Koha::Item') && $modulename eq 'CATALOGUING' && $actionname eq 'MODIFY' ) { $infos = "item " .
