This is done to allow the item information to be readily indexed (e.g., by Zebra), but means that each item modification transaction must keep the items table and the MARC XML in sync at all times. The items table will be considered authoritative. In other words, if there is ever a discrepancy between the items table and the MARC XML, the items table should be considered accurate. =head1 HISTORICAL NOTE Most of the functions in C were originally in the C module. =head1 CORE EXPORTED FUNCTIONS The following functions are meant for use by users of C =cut =head2 CartToShelf CartToShelf($itemnumber); Set the current shelving location of the item record to its stored permanent shelving location. This is primarily used to indicate when an item whose current location is a special processing ('PROC') or shelving cart ('CART') location is back in the stacks. =cut sub CartToShelf { my ( $itemnumber ) = @_; unless ( $itemnumber ) { croak "FAILED CartToShelf() - no itemnumber supplied"; } my $item = Koha::Items->find($itemnumber); if ( $item->location eq 'CART' ) { $item->location($item->permanent_location)->store; } } =head2 AddItemFromMarc my ($biblionumber, $biblioitemnumber, $itemnumber) = AddItemFromMarc($source_item_marc, $biblionumber[, $params]); Given a MARC::Record object containing an embedded item record and a biblionumber, create a new item record. The final optional parameter, C<$params>, may contain 'skip_record_index' key, which relayed down to Koha::Item/store, there it prevents calling of index_records, which takes most of the time in batch adds/deletes: index_records to be called later in C after the whole loop. You may also optionally pass biblioitemnumber in the params hash to boost performance of inserts by preventing a lookup in Koha::Item. $params: skip_record_index => 1|0 biblioitemnumber => $biblioitemnumber =cut sub AddItemFromMarc { my $source_item_marc = shift; my $biblionumber = shift; my $params = @_ ? shift : {}; my $dbh = C4::Context->dbh; # parse item hash from MARC my $frameworkcode = C4::Biblio::GetFrameworkCode($biblionumber); my ( $itemtag, $itemsubfield ) = C4::Biblio::GetMarcFromKohaField( "items.itemnumber" ); my $localitemmarc = MARC::Record->new; $localitemmarc->append_fields( $source_item_marc->field($itemtag) ); my $item_values = C4::Biblio::TransformMarcToKoha({ record => $localitemmarc, limit_table => 'items' }); my $unlinked_item_subfields = _get_unlinked_item_subfields( $localitemmarc, $frameworkcode ); $item_values->{more_subfields_xml} = _get_unlinked_subfields_xml($unlinked_item_subfields); $item_values->{biblionumber} = $biblionumber; $item_values->{biblioitemnumber} = $params->{biblioitemnumber}; $item_values->{cn_source} = delete $item_values->{'items.cn_source'}; # Because of C4::Biblio::_disambiguate $item_values->{cn_sort} = delete $item_values->{'items.cn_sort'}; # Because of C4::Biblio::_disambiguate my $item = Koha::Item->new( $item_values )->store({ skip_record_index => $params->{skip_record_index} }); return ( $item->biblionumber, $item->biblioitemnumber, $item->itemnumber ); } =head2 AddItemBatchFromMarc ($itemnumber_ref, $error_ref) = AddItemBatchFromMarc($record, $biblionumber, $biblioitemnumber, $frameworkcode); Efficiently create item records from a MARC biblio record with embedded item fields. This routine is suitable for batch jobs. This API assumes that the bib record has already been saved to the C and C tables. It does not expect that C is populated, but it will do so via a call to ModBibiloMarc. The goal of this API is to have a similar effect to using AddBiblio and AddItems in succession, but without inefficient repeated parsing of the MARC XML bib record. This function returns an arrayref of new itemsnumbers and an arrayref of item errors encountered during the processing. Each entry in the errors list is a hashref containing the following keys: =over =item item_sequence Sequence number of original item tag in the MARC record. =item item_barcode Item barcode, provide to assist in the construction of useful error messages. =item error_code Code representing the error condition. Can be 'duplicate_barcode', 'invalid_homebranch', or 'invalid_holdingbranch'. =item error_information Additional information appropriate to the error condition. =back =cut sub AddItemBatchFromMarc { my ($record, $biblionumber, $biblioitemnumber, $frameworkcode) = @_;
