Mojolicious::Lite with Template Toolkit - perl

Question

I'm trying to get Template Toolkit to work as the default renderer in Mojolicious::Lite. What I have:
use strict;
use warnings;
use Mojolicious::Lite;
use Mojolicious::Plugin::TtRenderer;
plugin tt_renderer => { template_options => { INCLUDE_PATH => './tmpl', DEBUG => 1 } };
get '/' => sub {
my $self = shift;
$self->render( 'index' );
};
app->renderer->default_handler( 'tt' );
app->start;
When I try to hit the test server, I get:
[Fri Oct 12 14:02:02 2012] [info] Listening at "http://*:3000".
Server available at http://127.0.0.1:3000.
[Fri Oct 12 14:02:08 2012] [debug] Your secret passphrase needs to be changed!!!
[Fri Oct 12 14:02:08 2012] [debug] GET / (Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:16.0) Gecko/20100101 Firefox/16.0).
[Fri Oct 12 14:02:08 2012] [debug] Routing to a callback.
[Fri Oct 12 14:02:08 2012] [debug] Nothing has been rendered, expecting delayed response.
This happens regardless of what I pass as parameters to 'render'. I can't seem to figure out how to get any useful debugging information out of this; but I haven't used Mojo before.
I've confirmed by sprinkling in some warn statements that my get handler is being called.

Answer 1

After looking at the source of Mojolicious::Plugin::TtRenderer::Engine, I figured it out. The plugin ignores the INCLUDE_PATH option passed to Template Toolkit, and instead gets the path from $app->renderer_paths. So updating my code to include:
app->renderer->default_handler( 'tt' );
app->renderer->paths( [ './tmpl' ] );
makes it work.
