=head3 can_be_transferred
|
|
|
|
$biblio->can_be_transferred({ to => $to_library, from => $from_library })
|
|
|
|
Checks if at least one item of a biblio can be transferred to given library.
|
|
|
|
This feature is controlled by two system preferences:
|
|
UseBranchTransferLimits to enable / disable the feature
|
|
BranchTransferLimitsType to use either an itemnumber or ccode as an identifier
|
|
for setting the limitations
|
|
|
|
Performance-wise, it is recommended to use this method for a biblio instead of
|
|
iterating each item of a biblio with Koha::Item->can_be_transferred().
|
|
|
|
Takes HASHref that can have the following parameters:
|
|
MANDATORY PARAMETERS:
|
|
$to : Koha::Library
|
|
OPTIONAL PARAMETERS:
|
|
$from : Koha::Library # if given, only items from that
|
|
# holdingbranch are considered
|
|
|
|
Returns 1 if at least one of the item of a biblio can be transferred
|
|
to $to_library, otherwise 0.

Returns host biblio record from MARC21 773 (undef if no 773 present).

It looks at the first 773 field with MARCorgCode or only a control

number. Complete $w or numeric part is used to search host record.

The optional parameter no_items triggers a check if $biblio has items.

If there are, the sub returns undef.

Called in list context, it also returns 773$g (related parts).

If there is no $w, we use $0 (host biblionumber) or $9 (host itemnumber)
|
|
to search for the host record. If there is also no $0 and no $9, we search
|
|
using author and title. Failing all of that, we return an undef host and
|
|
form a concatenation of strings with 773$agt for host information,
|
|
returned when called in list context.
