=head1 NAME
C4::Items - item management functions
=head1 DESCRIPTION
This module contains an API for manipulating item
records in Koha, and is used by cataloguing, circulation,
acquisitions, and serials management.
# FIXME This POD is not up-to-date
A Koha item record is stored in two places: the
items table and embedded in a MARC tag in the XML
version of the associated bib record in C<biblioitems.marcxml>.
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<C4::Items> were originally in
the C<C4::Biblio> module.
=head1 CORE EXPORTED FUNCTIONS
The following functions are meant for use by users
of C<C4::Items>
=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>, expected to 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<additem.pl> after the whole loop.
$params:
skip_record_index => 1|0
=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( $localitemmarc, $frameworkcode, 'items' );
my $unlinked_item_subfields = _get_unlinked_item_subfields( $localitemmarc, $frameworkcode );

$item_values->{biblionumber} = $biblionumber;
$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<biblio> and C<biblioitems> tables. It does
not expect that C<biblio_metadata.metadata> 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.

Given a hashref containing item fields, determine if it can be

Home branch, if not defined in branches table.

Holding branch, if not defined in branches table.

=head1 EXPORTED SPECIAL ACCESSOR FUNCTIONS
The following functions provide various ways of
getting an item record, a set of item records, or
lists of authorized values for certain item fields.
=cut
=head2 GetItemsForInventory

datelastseen => $datelastseen,
branchcode => $branchcode,
branch => $branch,
offset => $offset,
size => $size,
statushash => $statushash,
} );
Retrieve a list of title/authors/barcode/callnumber, for biblio inventory.
The sub returns a reference to a list of hashes, each containing
itemnumber, author, title, barcode, item callnumber, and date last
seen. It is ordered by callnumber then title.
The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
the datelastseen can be used to specify that you want to see items not seen since a past date only.
offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
$statushash requires a hashref that has the authorized values fieldname (intems.notforloan, etc...) as keys, and an arrayref of statuscodes we are searching for as values.
$iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

contains a number of keys. Most of them are attributes from the
C<biblio>, C<biblioitems>, C<items>, and C<itemtypes> tables in the
Koha database. Other keys include:
=over 2
=item C<$data-E<gt>{branchname}>
The name (not the code) of the branch to which the book belongs.
=item C<$data-E<gt>{datelastseen}>
This is simply C<items.datelastseen>, except that while the date is
stored in YYYY-MM-DD format in the database, here it is converted to
DD/MM/YYYY format. A NULL date is returned as C<//>.
=item C<$data-E<gt>{datedue}>
=item C<$data-E<gt>{class}>
This is the concatenation of C<biblioitems.classification>, the book's
Dewey code, and C<biblioitems.subclass>.
=item C<$data-E<gt>{ocount}>
I think this is the number of copies of the book available.
=item C<$data-E<gt>{order}>
If this is set, it is set to C<One Order>.
