Thanks Carl, that looks like a great solution. There's only one thing
I need to figure out before I can ditch the callback approach:
How to pass a custom error message to the validator?
Right now I have:
my $validator_alias = $field_alias->get_validator({ type => 'Callback' });
$validator_alias->callback(sub{
my $value = shift;
return 1 if $c->model('DIBC::Urls')->validator_unique_alias($value);
# here, validation failed
my $existing_url_full = $c->model('DIBC::Urls')->find({alias
=> $value})->url_full;
# add a hyperlink to the full URL in the error message
$validator_alias->message(
$validator_alias->message . ": <a
href=\"$existing_url_full\">" . $c->req->base . $value . '</a>'
);
return 0;
});
Could validators return their own error messages somehow?
Thanks,
Dan
