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; my $dbh = C4::Context->dbh; my $sth=$dbh->prepare("Insert into action_logs (timestamp,user,module,action,object,info,interface) values (now(),?,?,?,?,?,?)"); $sth->execute($usernumber,$modulename,$actionname,$objectnumber,$infos,$interface); $sth->finish; my $logger = Koha::Logger->get( { interface => 'intranet', category => "ActionLogs.$modulename.$actionname" } ); $logger->debug( sub { "ACTION LOG: " . to_json( { user => $usernumber, module => $modulename, action => $actionname, object => $objectnumber, info => $infos } ); } ); } =item cronlogaction &cronlogaction($infos); Convenience routine to add a record into action_logs table from a cron job.
