Hey Scott, hey all,
ok, here is what I did. I wrote a Dancer2::Template::MyApp module
following the example in Dancer2::Template::TemplateToolkit:
----
package Dancer2::Template::MyApp;
use 5.014;
use Moo;
use Template::Stash::AutoEscaping;
extends 'Dancer2::Template::TemplateToolkit';
around '_build_engine' => sub {
my $orig = shift;
my $self = shift;
my $tt = $self->$orig(@_);
# replace the stash object
$tt->service->context->{STASH} = Template::Stash::AutoEscaping-
>new(
$self->config->{STASH}
);
return $tt;
};
1;
----
Then I adapted my config.yml
----
template: "MyApp"
engines:
template:
MyApp:
start_tag: '[%'
end_tag: '%]'
ENCODING: utf8
STASH:
----
If I try to call a route in my application, the route crashes with:
Route exception: Failed to render template: undef error - Not a GLOB
reference at /usr/local/lib/x86_64-linux-
gnu/perl/5.20.2/Template/Provider.pm line 618.
If I comment out the replacement of the stash object it works
(unsurprisingly).
I have also tried to overload the entire build_engine method instead
of using "around" in order to construct the Template object with the
alternative stash object right away. This leads to the same result.
I went to line 618 of Template::Provider and printed out the
respective variable using Data::Dumper. It seems to be an arrayref
blessed into Template::Stash::AutoEscaping::Escaped::HTML. However,
Template::Provider obviously expects a GLOB reference.
I'd be very thankful if someone could help me on with this. I am
stuck.
Thank you and best wishes,
Lutz
