django-localized-fields | Implementation of localized model fields | Internationalization library

I'm trying to avoid having duplicate localized items stored in a Django-rest-framework app, django-localalized-fields package with a PostgreSQL database I can't find any way to make this work.

(https://pypi.org/project/django-localized-fields/)

I've tried writing custom duplicate detection logic in the Serializer, which works for create, but for update the localized fields become null (they are required fields, so I receive a not null constraint error). It seems to be django-localized-fields utility which is causing this problem.

The serializer runs correctly (create/update) when I'm not overriding create/update in the serializer by defining them separately.

I've also tried adding unique options to the database in the model, which does not work - duplicates are still created. Using the standard unique methods, or the method in the django-localized-fields documentation (uniqueness=['en', 'ro']).

I've also tried the UniqueTogetherValidator in Django, which also doesn't seem to support HStore/localizedfields.

I'd appreciate some help in tracking down either how to fix the update in the serializer or place a unique constraint in the database. Since django-localized-fields uses hstore in PostgreSQL it must be a common enough problem for applications using hstore to maintain uniqueness.

For those who aren't familiar, Hstore stores items as key/value pairs within a database. Here's an example of how django-localized-fields stores language data within the database:

"en"=>"english word!", "es"=>"", "fr"=>"", "frqc"=>"", "fr-ca"=>""
