83
84 C4::Items - item management functions
85
86 =head1 DESCRIPTION
87
88 This module contains an API for manipulating item
89 records in Koha, and is used by cataloguing, circulation,
90 acquisitions, and serials management.
91
92 # FIXME This POD is not up-to-date
93 A Koha item record is stored in two places: the
94 items table and embedded in a MARC tag in the XML
95 version of the associated bib record in C<biblioitems.marcxml>.
96 This is done to allow the item information to be readily
97 indexed (e.g., by Zebra), but means that each item
98 modification transaction must keep the items table
99 and the MARC XML in sync at all times.
100
101 The items table will be considered authoritative. In other
102 words, if there is ever a discrepancy between the items
103 table and the MARC XML, the items table should be considered
104 accurate.
105
106 =head1 HISTORICAL NOTE
107
108 Most of the functions in C<C4::Items> were originally in
109 the C<C4::Biblio> module.
110
111 =head1 CORE EXPORTED FUNCTIONS
112
113 The following functions are meant for use by users
114 of C<C4::Items>
115
116 =cut
117
118 =head2 CartToShelf
119
120 CartToShelf($itemnumber);
121
122 Set the current shelving location of the item record
123 to its stored permanent shelving location. This is
124 primarily used to indicate when an item whose current
125 location is a special processing ('PROC') or shelving cart
126 ('CART') location is back in the stacks.
127

144
145 my ($biblionumber, $biblioitemnumber, $itemnumber)
146 = AddItemFromMarc($source_item_marc, $biblionumber);
147
148 Given a MARC::Record object containing an embedded item
149 record and a biblionumber, create a new item record.

172
173 Given a hash containing item column names as keys,
174 create a new Koha item record.
175
176 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
177 do not need to be supplied for general use; they exist
178 simply to allow them to be picked up from AddItemFromMarc.
179
180 The final optional parameter, C<$unlinked_item_subfields>, contains
181 an arrayref containing subfields present in the original MARC
182 representation of the item (e.g., from the item editor) that are
183 not mapped to C<items> columns directly but should instead
184 be stored in C<items.more_subfields_xml> and included in
185 the biblio items tag for display and indexing.

234
235 Efficiently create item records from a MARC biblio record with
236 embedded item fields. This routine is suitable for batch jobs.
237
238 This API assumes that the bib record has already been
239 saved to the C<biblio> and C<biblioitems> tables. It does
240 not expect that C<biblio_metadata.metadata> is populated, but it
241 will do so via a call to ModBibiloMarc.
242
243 The goal of this API is to have a similar effect to using AddBiblio
244 and AddItems in succession, but without inefficient repeated
245 parsing of the MARC XML bib record.
246
247 This function returns an arrayref of new itemsnumbers and an arrayref of item
248 errors encountered during the processing. Each entry in the errors
249 list is a hashref containing the following keys:
250
251 =over
252
253 =item item_sequence
254
255 Sequence number of original item tag in the MARC record.
256
257 =item item_barcode
258
259 Item barcode, provide to assist in the construction of
260 useful error messages.
261
262 =item error_code
263
264 Code representing the error condition. Can be 'duplicate_barcode',
265 'invalid_homebranch', or 'invalid_holdingbranch'.
266
267 =item error_information
268
269 Additional information appropriate to the error condition.

340
341 This function updates an item record based on a supplied
342 C<MARC::Record> object containing an embedded item field.
343 This API is meant for the use of C<additem.pl>; for
344 other purposes, C<ModItem> should be used.
345
346 This function uses the hash %default_values_for_mod_from_marc,
347 which contains default values for item fields to
348 apply when modifying an item. This is needed because
349 if an item field's value is cleared, TransformMarcToKoha
350 does not include the column in the
351 hash that's passed to ModItem, which without
352 use of this hash makes it impossible to clear
353 an item field's value. See bug 2466.
354
355 Note that only columns that can be directly
356 changed from the cataloging and serials
357 item editors are included in this hash.

722
723 Retrieve a list of title/authors/barcode/callnumber, for biblio inventory.
724
725 The sub returns a reference to a list of hashes, each containing
726 itemnumber, author, title, barcode, item callnumber, and date last
727 seen. It is ordered by callnumber then title.
728
729 The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
730 the datelastseen can be used to specify that you want to see items not seen since a past date only.
731 offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
732 $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.
733
734 $iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

1319
1320 This hash keeps track of item columns that
1321 are strictly derived from other columns in
1322 the item record and are not meant to be set
1323 independently.
1324
1325 Each key in the hash should be the name of a
1326 column (as named by TransformMarcToKoha). Each
1327 value should be hashref whose keys are the
1328 columns on which the derived column depends. The
1329 hashref should also contain a 'BUILDER' key
1330 that is a reference to a sub that calculates
1331 the derived value.

1347 Given an item hash representing a new item to be added,
1348 calculate any derived columns. Currently the only
1349 such column is C<items.cn_sort>.

1371 Given an item hash representing a new item to be modified.
1372 calculate any derived columns. Currently the only
1373 such column is C<items.cn_sort>.
1374
1375 This routine differs from C<_set_derived_columns_for_add>
1376 in that it needs to handle partial item records. In other
1377 words, the caller of C<ModItem> may have supplied only one
1378 or two columns to be changed, so this function needs to
1379 determine whether any of the columns to be changed affect
1380 any of the derived columns. Also, if a derived column
1381 depends on more than one column, but the caller is not
1382 changing all of then, this routine retrieves the unchanged
1383 values from the database in order to ensure a correct
1384 calculation.
