[EP-tech] Order of subjects in view

[Florian Heß]

Hi,

I want to have the entries in a view menue sorted properly. My 
make_single_value_orderkey routine, however, does not seem to influence 
the response to the client (the problem is not the browser cache), even 
if that routine is actually executed. This has been tested successfully 
by running `perl -d ~/bin/generate_views --view=myview` with a 
$DB::single=1 in that routine: The routine has been executed and got 
passed every pair of subject $field => $value, and the returned order 
keys were perfect.

Did I miss something?

In cfg.d/views.pl:

         {
                 id => "schriftenreihen",
                 menus => [
                         {
                                 fields => [ "schriftenreihe_cluster_id" ],
                                 hideempty => 1,
                         },
                 ],
                 citation => "schriftenreihe_tr",
                 order => "schriftenreihe_order",
        }


In cfg.d/eprint_fields.pl:

           {
             'name' => 'schriftenreihe',
             'type' => 'compound',
             'fields' => [
                           {
                             'sub_name' => 'cluster_id',
                             'top' => 'sr',
                             'type' => 'subject',
                             'multiple' => 0,
                             'browse_link' => 'schriftenreihen',
                             'make_single_value_orderkey' =>
                                 \&schriftenreihe_sort_value
                           },
                           {
                             'sub_name' => 'order',
                             'type' => 'text',
                             'input_cols' => 10,
                             'allow_null' => 1,
                           },
                         ],
             'input_boxes' => 1,
           },

sub schriftenreihe_sort_value {
     my ($field, $value) = @_;
     $DB::single=1;

     $value = $field->{repository}
                    ->dataset("subject")
                    ->dataobj($value)
                    ->{data}
                    ->{name_name}[0]
                 ;

     # $value e.g. "Works by or about Ix Why"

     return join ", ", reverse $value =~ m{
             (\S+\w)                # given name
             (?:\s\w\.|\s[a-z]\S*)* # 2nd-name initials, "von" and alike
             \s*\b (\S+) \s* \z     # family name
         }xms;

}

After making these changes I did a `./epadmin reload $repo && epadmin 
reorder $repo subject &&  ./generate_views $repo --view=schriftenreihen`
, but the browser still displays the old naively sorted values.

Not expecting anyone answers this in 2012 - Wish you all a merry 
christmas, a good time and a happy new year! EPrints is a great superb 
system after all (my complains *g*)!

Regards,
Florian
