-=head1 NAME
-
-C4::Labels::Batch - A class for creating and manipulating batch objects in Koha
-
-=cut
+use base qw(C4::Creators::Batch);
-=head1 METHODS
+use autouse 'Data::Dumper' => qw(Dumper);
-=head2 C4::Labels::Batch->new(layout_id => layout_id, template_id => template_id, profile_id => profile_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, template_id => template_id, profile_id => profile_id);
- # Creates and returns a new batch object
-
- B<NOTE:> This batch is I<not> written to the database untill $batch->save() is invoked. You have been warned!
-
-=cut
+__PACKAGE__ =~ m/^C4::(.+)::.+$/;
+my $me = $1;
sub new {
- my ($invocant) = shift;
- my $type = ref($invocant) || $invocant;
- my $self = {
- batch_id => 0,
- items => [],
- branch_code => 'NB',
- batch_stat => 0, # False if any data has changed and the db has not been updated
- @_,
- };
- my $sth = C4::Context->dbh->prepare("SELECT MAX(batch_id) FROM labels_batches;");
- $sth->execute();
- my $batch_id = $sth->fetchrow_array;
- $self->{'batch_id'} = ++$batch_id;
- bless ($self, $type);
- return $self;
-}
-
-=head2 $batch->add_item(item_number => $item_number, branch_code => $branch_code)
-
- Invoking the I<add_item> method will add the supplied item to the batch object.
-
- example:
- $batch->add_item(item_number => $item_number, branch_code => $branch_code);
-
-=cut
-
-sub add_item {
my $self = shift;
- my $item_number = shift;
- my $query = "INSERT INTO labels_batches (batch_id, item_number, branch_code) VALUES (?,?,?);";

- $sth->execute($self->{'batch_id'}, $item_number, $self->{'branch_code'});
- if ($sth->err) {
- syslog("LOG_ERR", "C4::Labels::Batch->add_item : Database returned the following error on attempted INSERT: %s", $sth->errstr);
- return -1;
- }
- $query = "SELECT max(label_id) FROM labels_batches WHERE batch_id=? AND item_number=? AND branch_code=?;";
- my $sth1 = C4::Context->dbh->prepare($query);
- $sth1->execute($self->{'batch_id'}, $item_number, $self->{'branch_code'});
- my $label_id = $sth1->fetchrow_array;
- push (@{$self->{'items'}}, {item_number => $item_number, label_id => $label_id});
- $self->{'batch_stat'} = 0;
- return 0;
+ push @_, "creator", $me;
+ return $self->SUPER::new(@_);
}
-=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->remove_item()
-
- Invoking the I<remove_item> method will remove the supplied item from the batch object.
-
- example:
- $batch->remove_item();
-
-=cut
-
-sub remove_item {
- my $self = shift;
- my $label_id = shift;
- my $query = "DELETE FROM labels_batches WHERE label_id=? AND batch_id=?;";
- my $sth = C4::Context->dbh->prepare($query);
-# $sth->{'TraceLevel'} = 3;
- $sth->execute($label_id, $self->{'batch_id'});
- if ($sth->err) {
- syslog("LOG_ERR", "C4::Labels::Batch->remove_item : Database returned the following error on attempted DELETE: %s", $sth->errstr);
- return -1;
- }
- @{$self->{'items'}} = grep{$_->{'label_id'} != $label_id} @{$self->{'items'}};
- $self->{'batch_stat'} = 1;
- return 0;
-}
-
-=head2 $batch->save()
-
- Invoking the I<save> method attempts to insert the batch into the database. 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 syslog.
-
- example:
- my $exitstat = $batch->save(); # to save the record behind the $batch object
-
-=cut
-
sub save {
my $self = shift;
- foreach my $item_number (@{$self->{'items'}}) {
- my $query = "INSERT INTO labels_batches (batch_id, item_number, branch_code) VALUES (?,?,?);";
- my $sth1 = C4::Context->dbh->prepare($query);
- $sth1->execute($self->{'batch_id'}, $item_number->{'item_number'}, $self->{'branch_code'});
- if ($sth1->err) {
- syslog("LOG_ERR", "C4::Labels::Batch->save : Database returned the following error on attempted INSERT: %s", $sth1->errstr);
- return -1;
- }
- $self->{'batch_stat'} = 1;
- return $self->{'batch_id'};
- }
+ push @_, "creator", $me;
+ return $self->SUPER::save(@_);
}
-=head2 C4::Labels::Batch->retrieve(batch_id)
-
- Invoking the I<retrieve> method constructs a new batch object containing the current values for batch_id. The method returns
- a new object upon success and 1 upon failure. Errors are logged to the syslog.
-
- examples:
-
- my $batch = C4::Labels::Batch->retrieve(batch_id => 1); # Retrieves batch record 1 and returns an object containing the record
-
-=cut
-
sub retrieve {
- my $invocant = shift;
- my %opts = @_;
- my $type = ref($invocant) || $invocant;
- my $record_flag = 0;
- my $query = "SELECT * FROM labels_batches WHERE batch_id = ? ORDER BY label_id";
- my $sth = C4::Context->dbh->prepare($query);
-# $sth->{'TraceLevel'} = 3;
- $sth->execute($opts{'batch_id'});
- my $self = {
- batch_id => $opts{'batch_id'},
- items => [],
- };
- while (my $record = $sth->fetchrow_hashref) {
- $self->{'branch_code'} = $record->{'branch_code'};
- push (@{$self->{'items'}}, {item_number => $record->{'item_number'}, label_id => $record->{'label_id'}});
- $record_flag = 1;
- }
- return -2 if $record_flag == 0; # a hackish sort of way of indicating no such record exists
- if ($sth->err) {
- syslog("LOG_ERR", "C4::Labels::Batch->retrieve : Database returned the following error on attempted SELECT: %s", $sth->errstr);
- return -1;
- }
- $self->{'batch_stat'} = 1;
- bless ($self, $type);
- return $self;
+ my $self = shift;
+ push @_, "creator", $me;
+ return $self->SUPER::retrieve(@_);
}
-=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 syslog.
-
- 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 = {};
- my %opts = ();
- my $call_type = '';
- my @query_params = ();
if (ref($_[0])) {
- $self = shift; # check to see if this is a method call
- $call_type = 'C4::Labels::Batch->delete';
- @query_params = ($self->{'batch_id'}, $self->{'branch_code'});
+ my $self = shift; # check to see if this is a method call
+ push @_, "creator", $me;
+ return $self->SUPER::delete(@_);
}
else {
- %opts = @_;
- $call_type = 'C4::Labels::Batch::delete';
- @query_params = ($opts{'batch_id'}, $opts{'branch_code'});
+ push @_, "creator", $me;
+ return __PACKAGE__->SUPER::delete(@_); # XXX: is this too hackish?
}
- if ($query_params[0] eq '') { # If there is no template id then we cannot delete it
- syslog("LOG_ERR", "%s : Cannot delete batch as the batch id is invalid or non-existant.", $call_type);
- return -1;
- }
- my $query = "DELETE FROM labels_batches WHERE batch_id = ? AND branch_code =?";
- my $sth = C4::Context->dbh->prepare($query);
-# $sth->{'TraceLevel'} = 3;
- $sth->execute(@query_params);
- if ($sth->err) {
- syslog("LOG_ERR", "%s : Database returned the following error on attempted INSERT: %s", $call_type, $sth->errstr);
- return -1;
- }
- return 0;
