Hello Monks, I have been trying to use more of the MVC method for my web projects. To that end, I have be using the Template Toolkit a lot. On the this project I decided to use Class::DBI and Class::DBI::Pager. They work beautifully and I couldn’t be happier with them. The problem I am having is when I added Tie::Cycle to the mix. I pass the tied variable info my template, but only the first value is used. I’ve looked around a little and I haven’t seen any problem using ties in the template toolkit. Its probability something I am doing wrong, but I just don’t see it. Could someone point me in the right direction.

Thanks,

PS. Code and Template found below.


#!/usr/bin/perl

use strict;
use warnings;

use lib qw /./;

use CGI;
use Data; #Class::DBI
use Template;
use Tie::Cycle;

my $q = CGI->new;
my $file = 'index.html';
my $tt = Template->new({ INCLUDE_PATH => 'template/' });
tie my $cycle, 'Tie::Cycle', [ qw( FFFFFF CCCCCC ) ];

my $page = $q->param('page') || 1;

my $pager = Data->pager(5,$page);
my @data  = $pager->retrieve_all;

my $vars = {
                data    =>      \@data,
                pager   =>      $pager,
                cycle   =>      $cycle
          };

print $q->header;
$tt->process($file, $vars)
        || die "Template process failed: ", $tt->error(), "\n";
