Logically, I would do it that way, but make it a bit clearer:

my $form = $c->widget_result( 'my_form' );
if ( $form->valid && ! $form->errors ) {
    $c->forward( 'do_it' );
}

As long, as you're using $w->indicator(), then valid() will only be
true after a form submission.

Whether it's submitted is more a function of C::P::H::W, and what it
does with indicator(), which can be a field name or a sub-ref.
If you really want a single methodname for this, you could just add it
to the base of your Cat app.
