django-changerequest
django-changerequest is yet another model auditing/versioning package. As usual in cases like these, it was created because I wasn't quite happy with any of the existing solutions (that are still being actively maintained).
This django package started as an app inside one of my projects. When I wanted to use it in another project I put it into its own repository, but it still contained too many references to the original project. This repository starts fresh and attempts to (re)write the code to be now properly reusable, to the point where it is ready to put on PyPI (which it isn't yet at the moment).
Purpose
The purpose of django-changerequest is to record all user editing activity on the affected models, but also allow staged edits (where changes first have to be approved by a moderator before they're committed to the actual database).
