django-parler with unique field raise IntegrityError

[MehdiDRISSIB]

Hello

I have this field in my Product Model:
translations = TranslatedFields( name=models.CharField( max_length=256, unique=True, verbose_name=_('Name'), help_text=_("Enter a descriptive name for your product. This will be its title in your store.")), )

with unique=True

When I try to add the name qwerty to this object in english et french,

translations: {"en":{"name":"qwerty"},"fr":{"name":"qwerty"}}

I got this error:

django.db.utils.IntegrityError: duplicate key value violates unique constraint "product_product_translation_me_c1a12fbb_uniq" DETAIL: Key (name)=(qwerty) already exists.
But unique should be unique by product object, not unique by object and translations.

Many thanks for you help
