Galen Charlton 0bbcfeda0e replace syslog with warns
As discussed with Chris Nighswonger on #koha, this patch
removes the calls to syslog and replaces them with warns
so that error messages generated by the labels code
are sent to the Apache error log.  This avoids splitting
this sort of logging across multiple files and is consistent
with current practice in most of the rest of Koha.

=head1 NAME
C4::Labels::Batch - A class for creating and manipulating batch objects in Koha
=cut
=head1 METHODS
=head2 C4::Labels::Batch->new(layout_id => layout_id, tmpl_id => template_id, prof_id => prof_id)
Invoking the I<new> method constructs a new batch object with no items.
example:
my $batch = C4::Labels::Batch->new(layout_id => layout_id, tmpl_id => template_id, prof_id => prof_id);
# Creates and returns a new batch object
B<NOTE:> This batch is I<not> written to the database untill $batch->save() is invoked. You have been warned!
=cut
sub new {
my ($invocant, %params) = @_;
my $type = ref($invocant) || $invocant;
my $self = {
batch_id => 0,
layout_id => $params{layout_id},
tmpl_id => $params{tmpl_id},
prof_id => $params{prof_id},
items => [],
batch_stat => 0, # False if any data has changed and the db has not been updated
};
bless ($self, $type);
return $self;
}
=head2 $batch->add_item($item_number)
Invoking the I<add_item> method will add the supplied item to the batch object.
example:
$batch->add_item($item_number);
=cut
sub add_item {
my $self = shift;
my $item_num = shift;
push (@{$self->{items}}, $item_num);
$self->{batch_stat} = 0;
}
=head2 $batch->get_attr()
Invoking the I<get_attr> method will return the requested attribute.
example:
my @items = $batch->get_attr($attr);
=cut
sub get_attr {
my $self = shift;
return $self->{$_[0]};
}
=head2 $batch->delete_item()
Invoking the I<delete_item> method will delete the supplied item from the batch object.
example:
$batch->delete_item();
=cut
sub delete_item {
my $self = shift;
my $item_num = shift;
my $index = 0;
++$index until $$self->{items}[$index] == $item_num or $item_num > $#$self->{items};
delete ($$self->{items}[$index]);
$self->{batch_stat} = 0;
}
=head2 $batch->save()
Invoking the I<save> method attempts to insert the batch into the database if the batch is new and
update the existing batch record if the batch exists. The method returns the new record batch_id upon
success and -1 upon failure (This avoids conflicting with a record batch_id of 1). Errors are
logged to the Apache log.
example:
my $exitstat = $batch->save(); # to save the record behind the $batch object
=cut
sub save {
my $self = shift;
if ($self->{batch_id} > 0) {
foreach my $item_number (@$self->{items}) {
my $query = "UPDATE labels_batches SET item_number=?, layout_id=?, tmpl_id=?, prof_id=? WHERE batch_id=?;";
warn "DEBUG: Updating: $query\n" if $debug;
my $sth->C4::Context->dbh->prepare($query);
$sth->execute($item_number, $self->{layout_id}, $self->{tmpl_id}, $self->{prof_id}, $self->{batch_id});
if ($sth->err) {
warn sprintf('Database returned the following error: %s', $sth->errstr);
return -1;
}
}
}
else {
foreach my $item_number (@$self->{items}) {
my $query = "INSERT INTO labels_batches (item_number, layout_id, tmpl_id, prof_id) VALUES (?,?,?,?);";
warn "DEBUG: Inserting: $query\n" if $debug;
my $sth->C4::Context->dbh->prepare($query);
$sth->execute($item_number, $self->{layout_id}, $self->{tmpl_id}, $self->{prof_id});
if ($sth->err) {
warn sprintf('Database returned the following error: %s', $sth->errstr);
return -1;
}
my $sth1 = C4::Context->dbh->prepare("SELECT MAX(batch_id) FROM labels_batches;");
$sth1->execute();
my $batch_id = $sth1->fetchrow_array;
$self->{batch_id} = $batch_id;
return $batch_id;
}
}
$self->{batch_stat} = 1;
}
=head2 C4::Labels::Template->retrieve(template_id)
Invoking the I<retrieve> method constructs a new template object containing the current values for template_id. The method returns
a new object upon success and 1 upon failure. Errors are logged to the Apache log. Two further options may be accessed. See the example
below for further description.
examples:
my $template = C4::Labels::Template->retrieve(template_id => 1); # Retrieves template record 1 and returns an object containing the record
my $template = C4::Labels::Template->retrieve(template_id => 1, convert => 1); # Retrieves template record 1, converts the units to points,
and returns an object containing the record
my $template = C4::Labels::Template->retrieve(template_id => 1, prof_id => prof_id); # Retrieves template record 1, converts the units
to points, applies the given profile id, and returns an object containing the record
=cut
sub retrieve {
my $invocant = shift;
my %opts = @_;
my $type = ref($invocant) || $invocant;
my $query = "SELECT * FROM labels_batches WHERE batch_id = ? ORDER BY label_id";
my $sth = C4::Context->dbh->prepare($query);
$sth->execute($opts{batch_id});
if ($sth->err) {
warn sprintf('Database returned the following error: %s', $sth->errstr);
return 1;
}
my $self = {
items => [],
};
while (my $record = $sth->fetchrow_hashref) {
$self->{batch_id} = $record->{batch_id}; # FIXME: seems a bit wasteful to re-initialize these every trip: is there a better way?
$self->{layout_id} = $record->{layout_id};
$self->{tmpl_id} = $record->{tmpl_id};
$self->{prof_id} = $record->{prof_id};
push (@{$self->{items}}, $record->{item_number});
}
$self->{batch_stat} = 1;
bless ($self, $type);
return $self;
}
=head2 C4::Labels::Batch->delete(batch_id => batch_id) | $batch->delete()
Invoking the delete method attempts to delete the batch from the database. The method returns 0 upon success
and 1 upon failure. Errors are logged to the Apache log.
examples:
my $exitstat = $batch->delete(); # to delete the record behind the $batch object
my $exitstat = C4::Labels::Batch->delete(batch_id => 1); # to delete batch record 1
=cut
sub delete {
my $self = shift;
my %opts = @_;
if ((ref $self) && !$self->{'batch_id'}) { # If there is no batch batch_id then we cannot delete it from the db
warn 'Cannot delete batch: Batch has not been saved.';
return 1;
}
elsif (!$opts{batch_id}) {
warn 'Cannot delete batch: Missing batch_id.';
return 1;
}
my $query = "DELETE FROM labels_batches WHERE batch_id = ?";
my $sth = C4::Context->dbh->prepare($query);
$sth->execute($self->{'batch_id'});
return 0;
}
1;
