Because updating the total issues count associated with a bibliographic
record on issue could cause a significant load on the server, this
commit adds the syspref UpdateTotalIssuesOnCirc (which defaults to OFF
to match existing behavior). The syspref has the following description:
Do/Do not update a bibliographic record's total issues count whenever
an item is issued (WARNING! This increases server load significantly;
if performance is a concern, use the update_totalissues.pl cron job
to update the total issues count).
Bug 6557: automatically increment totalissues
Adds the ability to automatically increment biblioitems.totalissues
whenever an item is issued.
To test:
1) Choose a record with at least one item that can circulate
2) Check the value of 942$0 (you may need to look at the plain MARC view
on the OPAC). Most likely there won't be any 942$0 at all
3) Enable UpdateTotalIssuesOnCirc
4) Check out the item you selected
5) Check the value of 942$0 (you may need to look at the plain MARC view
on the OPAC). That value should now be one greater than before
6) Discharge the item
7) Disable UpdateTotalIssuesOnCirc
8) Check out the item you selected again
9) Check the value of 942$0 (you may need to look at the plain MARC view
on the OPAC). That value should not have changed
Bug 6557: add script to update totalissues from stats
NAME
update_totalissues.pl
SYNOPSIS
update_totalissues.pl --use-stats
update_totalissues.pl --use-items
update_totalissues.pl --commit=1000
update_totalissues.pl --since='2012-01-01'
update_totalissues.pl --interval=30d
DESCRIPTION
This batch job populates bibliographic records' total issues count
based on historical issue statistics.
--help Prints this help
-v|--verbose
Provide verbose log information (list every bib modified).
--use-stats
Use the data in the statistics table for populating total
issues.
--use-items
Use items.issues data for populating total issues. Note that
issues data from the items table does not respect the --since
or --interval options, by definition. Also note that if both
--use-stats and --use-items are specified, the count of biblios
processed will be misleading.
-s|--since=DATE
Only process issues recorded in the statistics table since
DATE.
-i|--interval=S
Only process issues recorded in the statistics table in the
last N units of time. The interval should consist of a number
with a one-letter unit suffix. The valid suffixes are h
(hours), d (days), w (weeks), m (months), and y (years). The
default unit is days.
--incremental
Add the number of issues found in the statistics table to the
existing total issues count. Intended so that this script can
be used as a cron job to update popularity information during
low-usage periods. If neither --since or --interval are
specified, incremental mode will default to processing the
last twenty-four hours.
--commit=N
Commit the results to the database after every N records are
processed.
--test Only test the popularity population script.
WARNING
If the time on your database server does not match the time on your Koha
server you will need to take that into account, and probably use the
--since argument instead of the --interval argument for incremental
updating.
=== TESTING PLAN ===
NOTE: in order to test this script, you will need to have some sort of
circulation data already existing in your Koha installation.
1) Disable UpdateTotalIssuesOnCirc
2) Run: misc/cronjobs/update_totalissues.pl --use-items -t -v
3) If you have total checkout data in your item records (i.e. anything
in 952$l), you should see messages like "Processing bib 43 (1 issues)"
4) Choose one of the lines that shows more than 0 issues, and view the
record with that biblionumber in the staff client, choosing the "Items"
tab (moredetail.pl). Add up the "Total checkouts" listed for each item,
and confirm it matches what the script reported
5) Run: misc/cronjobs/update_totalissues.pl --use-stats -t -v
6) If you have any circulation statistics in your database (i.e. any
'issue' entries in your statistics table), you should see messages
like "Processing bib 43 (1 issues)";
7) Choose one of the lines and view the record with that biblionumber in
the staff client, choosing the "Items" tab (moredetail.pl). If you
count the number of checkouts listed in each item's checkout history,
the total should match what the script reported.
8) Check out an item
9) Run: misc/cronjobs/update_totalissues.pl --use-stats
--incremental --interval=1h -t -v
10) You should see one line reporting a single circ for the bib record
associated with the item you just checked out (there may be more if
you checked out any books in the hour prior to running these tests
11) If the results in steps 4, 7, and 10 match the predictions, the
script worked
This patch to Koha was sponsored by the Arcadia Public Library and the
Arcadia Public Library Foundation in honor of Jackie Faust-Moreno, late
director of the Arcadia Public Library.

Tested this with my test data - numbers are correct and updated appropriately.
More importantly - if I do a popularity search, the most popular items *come up first*. Amazing.
