@fangyuan you can get the file path using Dancer's config
sub to get the path to the views directory ( via config->{views}
) and concatenate the subject file name to that. With that file path you can check if the file exists using the build in -f
perl file test function.
So all together your route would look like this:
get '/help/:subject' => {
my $subject = param 'subject';
my $tmpl = sprintf('help/%s.tt', $subject);
if ( -f config->{ 'views' }.'/'.$tmpl ) {
template $tmpl;
} else {
# Do something else instead of a 500
}
}

@lejeunerenard, thanks for the suggestion, it is one both simple and quick solution.
There is another method, check template render result. If Dancer::Response
returned, catch the error.
my $response = template 'help/' . $subject;
if (ref $response) { # Dancer::Response error
if ($response->status == 500) {
}
#.....
# normal output
$response->status(200);
return $response;
}
else { # normal output
$response;
}

Closing as answered query.
