some controller code:

sub purchase_manage : Local {
    my ( $self, $c ) = @_;
     $c->stash(no_wrapper => 0);
   $c->stash(merchants => [$c->model('WindyDB::Merchant')->all]);  # There are some Asian characters stored in DB.
   $c->stash(persons => [$c->model('WindyDB::person')->all]);    # ditto
         $c->stash(no_wrapper => 0);
    $c->stash(template => 'purchase_manage.tt');
