=head1 NAME
HTML::FormHandler::Render::WithTT - tt rendering
=head1 VERSION
version 0.40057
=head1 SYNOPSIS
A rendering role for HTML::FormHandler that allows rendering using
Template::Toolkit
package MyApp::Form;
use HTML::FormHandler::Moose;
extends 'HTML::FormHandler';
with 'HTML::FormHandler::Render::WithTT';
sub build_tt_template { 'user_form.tt' }
sub build_tt_include_path { ['root/templates'] }
....< define form >....
my $form = MyApp::Form->new(
$form->tt_render;
If you want to render with TT, you don't need this role. Just use
one of the TT form templates provided, form.tt or form_in_one.tt.
If you use this role to render, you are using two different TT
engines, with different sets of variables, etc, which doesn't
make much sense.
This is mainly useful as a testing aid and an example of using the
sample templates.
=head1 DESCRIPTION
Uses 'tt_render' instead of 'render' to allow using both TT templates and the
built-in rendering.
