AbstractValidator does not use messageKey when translating messages

[bkilinc]

I would like to translate validation messages using messageKeys as message strings may change. But translateMessage in AbstractValidator does not use $messageKey parameter for translating, even if it is defined as method parameter. It uses message string to translate.

protected function translateMessage($messageKey, $message)
{
    $translator = $this->getTranslator();
    if (! $translator) {
        return $message;
    }
    return $translator->translate($message, $this->getTranslatorTextDomain());
}

@bkilinc can you maybe outline a test case for what you'd like the behavior to be?

I want to use something like this as a translator object. This is not possible, because AbstractValidator does not pass messageKey to translator object.

class myTranslator implements \Zend\Validator\Translator\TranslatorInterface
{
    protected $translations = [
        'dateInvalid'     => "Invalid type given. String, integer, array or DateTime expected",
        'dateInvalidDate'=> "The input does not appear to be a valid date",
        'dateFalseFormat' => "The input does not fit the date format '%format%'",
    ];

    public function translate($messageKey, $textDomain = 'default', $locale = null)
    {
        return $this->translations[$messageKey];
    }
}

1. You can use zendframework/zend-i18n-resources and the messages of all validators are already translated. (you may already have seen this)
2. The AbstractValidator uses the text of the message, because if no translation exists than the message itself is used as fallback by the translator.
3. You can create a pull request to contribute your proposal. But keep in mind that every change of the current behaviour means a BC break and the need of a new major version. Because nobody knows if a user already has dateInvalid or dateFalseFormat in his translation files which can then lead to incorrect translations.

Thanks, I was creating my custom validator. I would like to use messageKey for looking up translations, because default message may also change. when I saw
"protected function translateMessage($messageKey, $message)"
in "AbstractValidator", I thought I could do this. But now I understand that, it is not possible with current implementation.
