Some days ago, after the merge of qs-rf to trunk, model field i18n was in trouble, so the principal package for this approach (django-multilingual) stopped working for the latest version of trunk.
This weekend we had a TransDb sprint, to try to improve our project, and contribute to fix this situation in any way.
The result: We fixed many issues on TransDb, now the project has a more conventional structure, and a setup script, and... TransDb is now working on trunk!
For achieving it we created a new branch called oldforms.
Try it now!
