Re: [dancer-users] How tod displaye aMulti Dimesional Hash in Template Toolkit

23 Aug 2020

      Hi Gabor,

Thank you very much for your help. I appreciate your answer and all
the wonderful tutorials at perlmaven, but so far I am unable to get
this answer to work for me. My my hash %season seems to look the same
as your %payload but when I try your solution only the name of the
player is displayed. I do not use 'use Template'; in my backend code
and am not really sure what the exact role of create.pl, is it for
teaching purposes or is there a step within it that I must apply to
get my %season to look like your %payload before I return it to my
Dancer app? I will continue to experiment with your solution and try
to find a place where I can post exactly what I am getting as a
result.

Thanks again,

Richard

I am not sure if this is what you meant, but using your data I wrote two
examples here: https://perlmaven.com/template-toolkit-hash-of-hash

I have the following perl multidimensional hash that is passed from
Dancer to Template Toolkit as a hash reference. I am having trouble
figuring out how to display it in Template Toolkit.
$VAR1 = {
          'TylerMontgomery(2022)' => {
                                   'so' => 1,
                                   'bb' => 1,
                                   'rbis' => 0,
                                   'atbats' => 7,
                                   'runs' => 2,
                                   'hits' => 2
                                 },
          'ChaseLangan(2022)' => {
                                     'runs' => 4,
                                     'hits' => 4,
                                     'atbats' => 5,
                                     'bb' => 0,
                                     'rbis' => 2,
                                     'so' => 1
                                   },
          'BryceJones(2021)' => {
                            'hits' => 2,
                            'runs' => 2,
                            'atbats' => 4,
                            'bb' => 1,
                            'rbis' => 4,
                            'so' => 1
                          },
};
This is how I iterate it in perl.
foreach my $name (sort keys %season) {
        printf "%-27.27s", "$name: ";
        foreach my $stat (sort keys %{ $season{$name} }) {
            printf "%-12.12s", "$stat: $season{$name}{$stat} ";
         ## cal. avg
 $season{$name}{AVG} = $season{$name}{hits} / $season{$name}{atbats};
        }
printf "%4s %.3f\n", "avg:", $season{$name}{AVG};
}
I then pass it back to my dancer app as a ref. with return \%season;
and then to template toolkit with:
template 'softball.tt' => {
'title' => 'Get Softball Season Stats',
        'Season' => $season,
}, {};
But I am lost trying to get it to display with template toolkit.
Here's what I've tried so far.
<table style="width:100%; line-height:40px;">
        <% FOREACH Season = Season %>
        <tr>
          <td width="5">Season.key <% Season.key %></td>
          <td width="5">Season.val <% Season.value %></td>
          <td width="5">Season.val.atbats <% Season.value.atbats %>
          <td width="5">Season.val.hits <% Season.value.hits %>
        </tr>
        <% END %>
Thanks for any help.
