The best/recommended way to translate Django database values
I also found this small project which purpose is to synchronize localized strings into standard message files for fields of registered models.
Example:
import vinaigrette
vinaigrette.register(YourModel, ['name', 'description'])
The standard command
$ manage.py makemessages
Would maintain messages for each distinct values found in registered fields.
I have not had the occasion to try it yet.
But this seems for me to be the simplest way to translate data from db.
I was reading up on my django extensions, and found the django-modeltranslation plugin. It seems to do exactly what you want it to do.
