Matt,
I don't know if any of this is useful to you. We do something that
sounds a bit like what you're after, by tweaking the template
include_path with each request. It's a classic path setting algorithm,
working back from most specific to least specific location.
ie, a template that says PROCESS "something.tt" that is the end result
of the URI /myapp/xx/yy/zz will look for something.tt in tt/xx/yy/zz,
then tt/xx/yy, then tt/xx, or tt/base. This gives us enormous
flexibility to tweak the output at any node or leaf of the tree.
You can create empty something.tt files in various places too, that
has a negating effect.
MyApp/C/Root.pm contains
sub auto {
...
$c->stash->{reportfolders} = split('/',$c->req->path);
...
}
MyApp/V/TT.pm contains
sub process {
my ($self, $c) = @_;
if (my $reportfolders = $c->stash->{reportfolders}) {
my @orig_path = @{$self->include_path};
my @this_path = ();
for my $orig_entry (@orig_path) {
for (my @folders = @$reportfolders; @folders; pop
@folders) {
push @this_path, join('/', $orig_entry, '..',
@folders);
}
push @this_path, $orig_entry;
}
@{$self->include_path} = @this_path;
#$c->log->debug(sprintf('%s:process: dynamic include_path is
%s.', __PACKAGE__, join(':',@{$self->include_path})));
$self->SUPER::process($c);
@{$self->include_path} = @orig_path;
} else {
$self->SUPER::process($c);
}
}
Hope that's useful.
cheers

Thanks everyone for your input, I'm certainly gathering that there
is nothing preexisting that does what I'm looking to do. I'll
continue to clean up my version and throw it on CPAN if it seems
appealing enough. As a quick overview the basic premise is a more
direct link from the path to the template which would be used for
those times when the URI path determines presentation after passing
through a reusable action handler which tailors content (and doesn't
necessarily have to worry about the template selection). This is
presently done in the auto action so that overriding the behavior is
natural and any extended logic can be handled when and where desired.
