i don't know about 'best practice' but what i have done is create a
plugin that exposes $c->alert_error(), $c->alert_info(), and a couple
of similar ones.
the controller does, roughly:
$c->alert_error('You screwed up.'); # moreorless push @{ $c->flash-
>{alert_errors} }, @_;
$c->alert_info($obj->name . ' updated!');
these are stored in the flash (for redirect-after-successful-post).
i then populate stash/globals with the flash contents before
rendering the view (mason in my case).
my mason autohandler then displays any @alert_errors/etc as appropriate.
i use the same system for $c->form_error(username => 'Username
missing.'), which is deleted into %form_errors before rendering the
view. my custom form generators (mason components) know how to
display those errors as appropriate when the form is rendered.

I'm hoping there's a 'best practice' or common pattern for reporting
errors and messages to templates (not necessarily just forms).
I find myself doing stuff like,
my @errors; my @messages;
# ...
if ($some_err_condition) {
push @errors, "whoops";
} else {
$obj->update;
push @messages, $obj->name . " updated!";
}
# ...
$c->stash(messages => join "<br/>", @messages);
$c->stash(errors => join "<br/>", @errors);
Which is then tediously copy & pasted amongst controllers that do that
reporting.
And then my template says something like,
[% IF errors %]
<p class="error">[% errors %]</p>
[% END %]
[% IF messages %]
<p class="messages">[% messages %]</p>
[% END %]
At least with the template I have that as a MACRO I can call variously
but I'd at least like a way to have some kind of
context/controller-wide way of dealing with these errors & messages. I
don't quite understand Cat's object model well enough to do this
globally myself yet.
