Attribution

Some concepts and code come from https://github.com/deschler/django-modeltranslation, which is in turn inspired by https://github.com/zmathew/django-linguo

We started this solution at Zostera because we did not like:

• The way django-modeltranslation adds one field per language (and thus requires a migration when adding a language);
• The unpredictability of the original field.

Since JSONB is supported by Postgres now, we developed this approach.
