hash of a hash into template toolkit?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Has anyone tried feeding a hash of a hash into the template tool kit? i'm having trouble doing this. heres the perl code it prints out just fine but when i pass it to the template it doesnt do anything perl code

 foreach my $i (keys %results){
    print "rule_id - $i\n";
    foreach my $k (keys %{$results{$i}}){
      print "$k -> $results{$i}->{$k}\n";
    }
    print "----------------------------------\n";
  }


  $self->process_template( template => $login_template, data => { resu
+lts => \%results});

Template toolkit code

[% FOREACH r = results %]
  [% r %]                       <---- this prints out a hash
[% END %]

`[% FOREACH r = results %] [% r %] <---- this prints out a hash [% END %]` [download] That's because `r` is a hash reference. If you want to show data in r, you need to say something like `[% FOREACH r = results %] [% r.foo %] and [% r.bar %] [% END %]` [download] Read all about it in the Template Toolkit's manual, section on Hash Array References. Also, from looking at the code above, you may benefit from reading the Data::Dumper docs. It's typically a much handier way of displaying a data structure than rolling your own. _______________ D a m n D i r t y A p e Home Node \| Email	[reply] [d/l] [select]
