I do something like this in my delete actions:

sub delete : Local {
    my ( $self, $c, $id, $delete ) = @_;

    return $c->internal_redirect('list', { message => 'Invalid Item Selected' } )
        unless my $item = DB::Item->retrieve( $id );


    unless ( $delete && $c->req->method eq 'POST' ) {
        $c->stash->{template} = 'verify_delete.xhtml';
        $c->stash->{item} = $item;
        return;
    }

    if ( $c->req->parameters->{yes} ) {
        $c->stash->{message} = 'Deleted [' . $item->name . ']';
        $item->delete;
    }

    return $c->internal_redirect('list');
}
