如何用石墨烯查询可翻译的字段

Question

假设一个模型已翻译如下所示的字段，我们如何用django-graphene查询这些？

from parler.models import TranslatableModel, TranslatedFields

class Article(TranslatableModel):
    #regular fields
    publishing_date = models.DateTimeField(_('publishing date'),
                                           default=now)
    # translated fields
    translations = TranslatedFields(
        title=models.CharField(_('title'), max_length=234),
        slug=models.SlugField(
            verbose_name=_('slug'),
            max_length=255,
            db_index=True,
            blank=True,
        ),
        meta_title=models.CharField(
            max_length=255, verbose_name=_('meta title'),
            blank=True, default=''),
        meta_description=models.TextField(
            verbose_name=_('meta description'), blank=True, default=''),
        meta_keywords=models.TextField(
            verbose_name=_('meta keywords'), blank=True, default=''),
    )

对于注册“未知”字段，我会执行以下操作：

@convert_django_field.register(GeopositionField)
def convert_geofield_to_string(field, registry=None):
     return graphene.String(description=field.help_text, required=not field.null)

...但这不适用于此。有什么想法吗？
