Any app for i18n of models for django in appengine or non-sql?

I'm working in a project with django and GAE, but I need internationalization for models, I try with datatrans and django-model-i18n but both applications make a heavy use of sql i开发者_StackOverflown databases and doesn't work with app-engine.

Theres is any application for i18n to model's level and work with non-sql databases?

Until now, the most accurated project for work model field translation in app engine is modeltranslation because:

1. Add fields by language in the same table, and doesn't is a problem in app engine, perhaps in a SQL database.
2. This project 'hacks' AdminModel for show a special interface for i18n.
3. Has medium activity and is recent
4. For the translation in templates and views, don't make complex joins, just select.
5. Easy to install
6. In app engine works perfectly for make third party models translatables
