Question

I have two classes:

class Translation(models.Model):
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    object = generic.GenericForeignKey('content_type', 'object_id')
    field = models.CharField(max_length=64) #field from the translated model
    language = models.CharField(max_length=8, choices=settings.LANGUAGES, verbose_name=_("language"))
    text = models.TextField() #translation

class Category(models.Model):
    translations = generic.GenericRelation(Translation)
    name = models.CharField(max_length=128, verbose_name=_("Name"))
    slug = models.SlugField(blank=True, default="", verbose_name=_("Slug"))

Is there a way to order Categories by translation__text filtering the order_by by the current language? If I use

Category.objects.all().order_by("translations__text")

I get categories sorted by all translations, not just the current language. I guess, what I ned is filtering the order_by set somehow (to use only translations of a given language)? Is there a way to do so?

DB = PostgreSQL

Thanks for help!

Try this:

Category.objects.filter(translations__language='en').order_by("translations__text")
