>
>This patch adds a method based on the original idea from Nick, but on
>Koha::Items.
>
>The idea is to build a proper filter, based on the current rules for
>hiding things, directly on the DBIC query. The caller takes care of
>knowing if the filtering should apply (i.e. checking the patron category
>exceptions) and then it would do something like:
>
>    my @items;
>    if ( <patron_category_does_not_have_exception> ) {
>        @items = $biblio->items->filter_by_visible_in_opac(
>            {
>                rules => $rules
>            }
>        );
>    }
>    else {
>        # still want to enforce 'hidelostitems'
>        @items = $biblio->items->filter_by_visible_in_opac;
>    }
>
>To test:
>1. Apply this patches
>2. Run:
>   $ kshell
>  k$ prove t/db_dependent/Koha/Items.t
>=> SUCCESS: Tests pass!
>3. Look at the use cases on the tests, read the code
>=> SUCCESS: It all makes sense
>4. Compare with Koha::Item->hidden_in_opac
>=> SUCCESS: It all makes sense
>5. Sign off :-D
