[EP-tech] Re: citation modification

Ah, it's a compound multiple field.

You need to render creators_name, not creators.  Also, try putting the render_single_value in the name subfield definition -- I'm not sure if it will work off the top of my head, but it makes sense.  I've modified the code below.  Let us know if it works.

I modified eprint_fields.pl:
{
       name => 'creators',
       type => 'compound',
       multiple => 1,
       fields => [
               {
                       sub_name => 'name',
                       type => 'name',
                       hide_honourific => 1,
                       hide_lineage => 1,
                       family_first => 1,
                       render_single_value => 'render_name_with_initials',
               },
               {
                       sub_name => 'id',
                       type => 'text',
                       input_cols => 20,
                       allow_null => 1,
               }
       ],
       input_boxes => 2,
},

I introduced eprint_render_single.pl:
print STDERR "It's Me :)\n";
$c->{render_name_with_initials} = sub
{
       print STDERR "It's You :)\n";
       my( $field, $repo, $value ) = @_;
       my $family = $value->{family};
       my $given = $value->{given};
       return $repo->xml->create_text_node( 'foo' );
}

I used Test.pl
#!/usr/bin/perl -I/opt/eprints3/perl_lib

use strict;
use warnings;
use EPrints;

my $ep = EPrints->new;
my $repo = $ep->repository('b40literatur');

my $eprint = $repo->dataset('eprint')->dataobj(3);

print STDERR EPrints::Utils::tree_to_utf8($eprint->render_value('creators_name'));

Hi Adam,

there's obviously something wrong, although I think to follow all your instructions :(

I modified eprint_fields.pl:
{
       name => 'creators',
       type => 'compound',
       multiple => 1,
       fields => [
               {
                       sub_name => 'name',
                       type => 'name',
                       hide_honourific => 1,
                       hide_lineage => 1,
                       family_first => 1,
               },
               {
                       sub_name => 'id',
                       type => 'text',
                       input_cols => 20,
                       allow_null => 1,
               }
       ],
       render_single_value => 'render_name_with_initials',
       input_boxes => 2,
},

I introduced eprint_render_single.pl:
print STDERR "It's Me :)\n";
$c->{render_name_with_initials} = sub
{
       print STDERR "It's You :)\n";
       my( $field, $repo, $value ) = @_;
       my $family = $value->{family};
       my $given = $value->{given};
       return $repo->xml->create_text_node( 'foo' );
}

I used Test.pl
#!/usr/bin/perl -I/opt/eprints3/perl_lib

use strict;
use warnings;
use EPrints;

my $ep = EPrints->new;
my $repo = $ep->repository('b40literatur');

my $eprint = $repo->dataset('eprint')->dataobj(3);

print STDERR EPrints::Utils::tree_to_utf8($eprint->render_value('creators'));

But I got finally for perl Test.pl
It's Me :)
CreatorsEmailFoote, H.W.UNSPECIFIEDLevy, L.H.UNSPECIFIED

Thus my extra subroutine is never called even after apache's restart and database update?!

Thanks for any hint
Thomas
