Bug 18208: Add RecordProcessor filter to inject not onloan count to MARC records

This patch adds a new filter for MARC records to be used with
Koha::RecordProcessor. It's purpose is to inject the information about
items not-onloan in a fixed subfield, 999$x.

To test:
- Apply the patch
- Run:
  $ prove t/db_dependent/Koha/Filter/EmbedItemsAvailability.t
=> SUCCESS: Tests pass!
- Sign off :-D

Comment 3 Marcel de Rooy 2017-03-10 10:56:02 UTC
my $items = Koha::Items->search({ biblionumber => $biblionumber });
+
+    while ( my $item = $items->next ) {
+        $not_onloan_items++
+            if not $item->onloan;
+    }
Can't you combine that in one statement?

In general: Do I understand correctly that this is not an optional filter? We will always save the not onloan count to 999$x?
Can you also add some explanation on this report why we definitely need it?
At this point we are not using it in the codebase. But if we should do after some time, would it feel good to rely on a field in the search engine when we can generate the count in one Koha::Items call ?
No blockers, just convince me..

The record will always inject that. And is going to be used on indexing only. See bug 18098.

When it comes to filtering search results (records with available items this time) we need the index for being able to build the filtering query. We already do that but the query is not working, and this way writing the query seems straightfowrad. Just check if the index has a value higher than 0. Period.

RecordProcessor filters should be used for lots of things (specially stuff done in C4::Biblios) like embedding items...

Removes the loop by moving the onloan test to the query.

Test plan:
Run the test again.

Pushed to master for 17.05, thanks Tomas, Marcel!
Comment 8 Katrin Fischer 2017-04-16 12:23:47 UTC
This won't get ported back to 16.11.x as it is an enhancement.
