    use Validation::Class::Simple;
    my $rules = Validation::Class::Simple->new(
        fields => {
            access_code  => {
                default => 'demo123'
            }
        }
    );
    # set parameters to be validated
    $rules->params->add($parameters);
    # validate

        # handle the failures
    }

Validation::Class::Directive::Default is a core validation class field directive that holds the value which should be used if no parameter is supplied.
alternative argument: a-coderef-returning-a-default-value
This directive can be passed a single value or a coderef which should return the value to be used as the default value:
    fields => {
        access_code => {
            default => sub {
                my $self = shift; # this coderef will receive a context object
                return join '::', lc __PACKAGE__, time();
            }
        }
    }
