=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.
Consequently, all code that creates, modifies, or deletes
item records B<must> use an appropriate function from
C<C4::Items>. If no existing function is suitable, it is
better to add one to C<C4::Items> than to use add
one-off SQL statements to add or modify items.
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 GetItem
$item = GetItem($itemnumber,$barcode,$serial);
Return item information, for a given itemnumber or barcode.
The return value is a hashref mapping item column
names to values. If C<$serial> is true, include serial publication data.
=cut
sub GetItem {
my ($itemnumber,$barcode, $serial) = @_;
my $dbh = C4::Context->dbh;
my $item;
if ($itemnumber) {
$item = Koha::Items->find( $itemnumber );
} else {
$item = Koha::Items->find( { barcode => $barcode } );

( $data->{'serialseq'}, $data->{'publisheddate'} ) = $ssth->fetchrow_array();
}
return $data;
} # sub GetItem
=head2 CartToShelf
CartToShelf($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";
}

$item->{location} = $item->{permanent_location};
ModItem($item, undef, $itemnumber);
}
}
=head2 ShelfToCart
ShelfToCart($itemnumber);
Set the current shelving location of the item
to shelving cart ('CART').
=cut
sub ShelfToCart {
my ( $itemnumber ) = @_;
unless ( $itemnumber ) {
croak "FAILED ShelfToCart() - no itemnumber supplied";

ModItem($item, undef, $itemnumber);
}
=head2 AddItemFromMarc
my ($biblionumber, $biblioitemnumber, $itemnumber)
= AddItemFromMarc($source_item_marc, $biblionumber);
Given a MARC::Record object containing an embedded item
record and a biblionumber, create a new item record.
=cut
sub AddItemFromMarc {
my ( $source_item_marc, $biblionumber ) = @_;
my $dbh = C4::Context->dbh;
# parse item hash from MARC
my $frameworkcode = C4::Biblio::GetFrameworkCode( $biblionumber );

return AddItem($item, $biblionumber, $dbh, $frameworkcode, $unlinked_item_subfields);
}
=head2 AddItem
my ($biblionumber, $biblioitemnumber, $itemnumber)
= AddItem($item, $biblionumber[, $dbh, $frameworkcode, $unlinked_item_subfields]);
Given a hash containing item column names as keys,
create a new Koha item record.
The first two optional parameters (C<$dbh> and C<$frameworkcode>)
do not need to be supplied for general use; they exist
simply to allow them to be picked up from AddItemFromMarc.
The final optional parameter, C<$unlinked_item_subfields>, contains
an arrayref containing subfields present in the original MARC
representation of the item (e.g., from the item editor) that are
not mapped to C<items> columns directly but should instead
be stored in C<items.more_subfields_xml> and included in
the biblio items tag for display and indexing.

=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.

=head2 ModItemFromMarc
ModItemFromMarc($item_marc, $biblionumber, $itemnumber);
This function updates an item record based on a supplied
C<MARC::Record> object containing an embedded item field.
This API is meant for the use of C<additem.pl>; for
other purposes, C<ModItem> should be used.
This function uses the hash %default_values_for_mod_from_marc,
which contains default values for item fields to
apply when modifying an item. This is needed because
if an item field's value is cleared, TransformMarcToKoha
does not include the column in the
hash that's passed to ModItem, which without
use of this hash makes it impossible to clear
an item field's value. See bug 2466.
Note that only columns that can be directly
changed from the cataloging and serials
item editors are included in this hash.
Returns item record

Change one or more columns in an item record and update
the MARC representation of the item.
The first argument is a hashref mapping from item column
names to the new values. The second and third arguments
are the biblionumber and itemnumber, respectively.
The fourth, optional parameter (additional_params) may contain the keys
unlinked_item_subfields and log_action.
C<$unlinked_item_subfields> contains an arrayref containing
subfields present in the original MARC
representation of the item (e.g., from the item editor) that are
not mapped to C<items> columns directly but should instead
be stored in C<items.more_subfields_xml> and included in
the biblio items tag for display and indexing.
If one of the changed columns is used to calculate
the derived value of a column such as C<items.cn_sort>,
this routine will perform the necessary calculation
and set the value.
If log_action is set to false, the action will not be logged.
If log_action is true or undefined, the action will be logged.

=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.
Some of the functions in this group are candidates
for refactoring -- for example, some of the code
in C<GetItemsByBiblioitemnumber> and C<GetItemsInfo>
has copy-and-paste work.

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

=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}>

=head2 %derived_columns
This hash keeps track of item columns that
are strictly derived from other columns in
the item record and are not meant to be set
independently.
Each key in the hash should be the name of a
column (as named by TransformMarcToKoha). Each
value should be hashref whose keys are the
columns on which the derived column depends. The
hashref should also contain a 'BUILDER' key
that is a reference to a sub that calculates
the derived value.

Given an item hash representing a new item to be modified.
calculate any derived columns. Currently the only

This routine differs from C<_set_derived_columns_for_add>
in that it needs to handle partial item records. In other
words, the caller of C<ModItem> may have supplied only one
or two columns to be changed, so this function needs to
determine whether any of the columns to be changed affect
any of the derived columns. Also, if a derived column
depends on more than one column, but the caller is not
changing all of then, this routine retrieves the unchanged
values from the database in order to ensure a correct
calculation.
