Exists a testing django project. This project can use as demo project, because django-inplaceedit is totally adapted to it.
Also you can use the demo project of django-inplaceedit-bootstrap
The backend has unit test, to check it.:
cd testing python run_tests.py
You can see this django-inplaceedit works (without changes) from django 1.2, and even in previous versions of Django (1.1 and 1.0) works with some customizations.
