Perl Catalyst - Couldn't render template..........not found

Question

The error I am getting in the development server:

What I am doing:

I have the following Controller/Homescreen.pm:

package Myproject::Controller::Homescreen;

use strict;
use warnings;
use parent 'Catalyst::Controller';
use Data::Dumper;
use JSON;

__PACKAGE__->config->{namespace} = '';

sub homescreen :Path('/homescreen') :Args(0)  {

        my ( $self, $c ) = @_;
        print STDERR "IN THE HOMESCREEN ACTION\n";


        $c->stash({template => 'homescreen/homescreen.tt2',
                   title => 'Home Screen'
                 });
}

I have the following View/HTML.pm:

package Myproject::View::HTML;
use Moose;
use namespace::autoclean;

extends 'Catalyst::View::TT';

__PACKAGE__->config({
    #Changed default TT extension to TT2
    TEMPLATE_EXTENSION => '.tt2',
    render_die => 1,
});

I have the following lib/Myproject.pm:

__PACKAGE__->config(
    name => 'Myproject',
    # Disable deprecated behavior needed by old applications
    disable_component_resolution_regex_fallback => 1,
    #enable_catalyst_header => 1, # Send X-Catalyst header
);

__PACKAGE__->config(
        #Configure the view
        'View::HMTL' => {
                #Set the location for TT files
                INCLUDE_PATH => [
                        __PACKAGE__->path_to( 'root', 'src' ),
                ],
        },
);


# Start the application
__PACKAGE__->setup();

I then have a root/src/homescreen/homescreen.tt2 withing my Catalyst directory that contains all my html code (eventually it will use the template toolkit,but at the moment it is purely html and javscript code which I know is fine).

The error I get on the application page in my browser is:

Couldn't render template "homescreen/homescreen.tt2: file error - homescreen/homescreen.tt2: not found"

I have tried using DEBUG => 'undef' in my HTML.pm View to help with debugging, but I don't seem to get any extra output.

There is probably something very obvious I am overlooking but I cannot work out what it is.

Update

I have just noticed the following in the Config section of my browser debug screen:

Config

  do {
  my $a = {
    "Action::RenderView" => {
      ignore_classes => [
                          "DBIx::Class::ResultSource::Table",
                          "DBIx::Class::ResultSourceHandle",
                          "DateTime",
                        ],
      scrubber_func  => sub { ... },
    },
    "disable_component_resolution_regex_fallback" => 1,
    "home" => "/home/fred/Myproject",
    "name" => "Myproject",
    "Plugin::ConfigLoader" => {},
    "Plugin::Static::Simple" => {
      debug => 1,
      dirs => [],
      ignore_dirs => [],
      ignore_extensions => ["tmpl", "tt", "tt2", "html", "xhtml"],   <---- IS THIS SIGNIFICANT AT ALL?
      include_path => [
        bless({
          dirs => ["", "home", "fred", "Myproject", "root"],
          file_spec_class => undef,
          volume => "",
        }, "Path::Class::Dir"),
      ],
      mime_types => {},
      mime_types_obj => bless({}, "MIME::Types"),
      no_logs => 1,
    },
    "root" => 'fix',
    "stacktrace" => { context => 3, verbose => 0 },
    "static" => 'fix',
    "View::HMTL" => {
      INCLUDE_PATH => [
        bless({
          dirs => ["", "home", "fred", "Myproject", "root", "src"],
          file_spec_class => undef,
          volume => "",
        }, "Path::Class::Dir"),
      ],
    },
  };
  $a->{"root"} = $a->{"Plugin::Static::Simple"}{include_path}[0];
  $a->{"static"} = $a->{"Plugin::Static::Simple"};
  $a;
}

I take it this means it is ignoring my template file because it has the .tt2 file extension?

However, I am not setting this ignore_extensions attribute anywhere in my Catalyst project? Is this the cause of my problem or something totally unrelated?

Are you the root user? Maybe your webserver is not running as root and thus cannot find the template. Try loading [CWD](http://perldoc.perl.org/Cwd.html) and let put something like `die cwd;` in your controller to see where your stuff is running. If it's in another user's homedir, chances are that user has no permission to read files in `/root`. — simbabque, Dec 12 '13 at 21:43
I did check file permissions before posting (which I forgot to mention). Also, I did just try running the development server as root, but it made no difference. I still get the same error message. Any other ideas? thanks — yonetpkbji, Dec 12 '13 at 21:48
Dump out `__PACKAGE__->config->{'View::HTML'}` to STDERR and confirm the path is what you anticipate it should be. — RET, Dec 13 '13 at 00:47
Have you try to give the full path to your template in the controller? — Fotis_zzz, Dec 13 '13 at 09:28
Also try to remove "root" from __PACKAGE__->path_to in the lib/Myproject.pm file — Fotis_zzz, Dec 13 '13 at 10:10
The template has to be in the directory 'root/src/homescreen' within the catalyst project directory, not in '/root/src/homescreen'. — dgw, Dec 13 '13 at 21:04
@dgw - Apologies, my template is in the 'root/src/homescreen' within the catalyst project directory... it was a typo on my part that has now been edited, thanks — yonetpkbji, Dec 20 '13 at 22:15
@RET - When using `print STDERR __PACKAGE__->config->{'View::HTML'};` as you suggested I get an error in the Catalyst debug output `Use of uninitialized value in print at /home/fred/MyProject/script/../lib/MyProject/Controller/Homescreen.pm line 10.` — yonetpkbji, Dec 20 '13 at 22:21
Well, I did mean `print STDERR Dumper(__PACKAGE__->..)`, but possibly it's too early in the chain for that to work correctly. Is the problem resolved? — RET, Dec 21 '13 at 02:03
No, it's still not fixed, still getting the `Couldn't render template...` issue. I'm sure it must be something obvious but cannot see what... — yonetpkbji, Dec 21 '13 at 15:08
Pretty certain it's not a permissions issue because I changed whole directory to 777 with `chmod -R ` to make sure, but still nothing changed. — yonetpkbji, Dec 21 '13 at 15:52
Just found something that may or may not be of significance, please see the update to my question... thanks a lot — yonetpkbji, Dec 21 '13 at 16:12
The ignore_extensions is only for the Static::Simple plugin, so that isn't the problem. See the answer below for the solution :-) — asjo, Dec 21 '13 at 22:02

It looks like your configuration isn't taking effect. Try putting your template in root/homescreen/homescreen.tt2 instead of root/src/homescreen/homescreen.tt2, and Catalyst finds it.

Ahh, you have a typo in your lib/Myproject.pm:

__PACKAGE__->config(
        #Configure the view
        'View::HMTL' => {

Try 'View::HTML' instead (notice you have HMTL - wrong spelling).

Great spot, thanks... I was expecting it to be something obvious but not quite that obvious... the amount of times I've looked at this I should of spotted it -thanks again – yonetpkbji Dec 22 '13 at 12:48
