TranslatableAdmin exception when no translations on default language

[Marcon]

Hi. I have some simple configuration like this

LANGUAGES = (
    ('ru', 'RU'),
    ('en', 'EN'),
    ('kz', 'KZ'),
)

PARLER_LANGUAGES = {
    None: (
        {'code': 'ru'},
        {'code': 'en'},
        {'code': 'kz'},
    ),
    'default': {
        'fallbacks': ['ru', 'en', 'kz'],
        'hide_untranslated': False,
    }
}

Default language is russian.
I have some translated models in my app and editing translation trough admin site using TranslatableAdmin
Everything works fine when I starting translation from default language, and I can create russian translation first and after this create english or kazakh language on any order.
But if I create english(or kazakh) translation first and probably leave only english translation for this entry, when I attempting switch to english tab and edit entry, I have exception "parler.models.DoesNotExist: MyModel does not have a translation for the current language!" and I cannot edit entry until default language translation created

@Marcon I think you have to change 'None' (PARLER_LANGUAGES key) to your SITE_ID.

The fastest and most common is to add this to the base model:

        except TranslationDoesNotExist:
            return ''
