[Django]-What is the best framework/reusable app for caching model instances (object level cache) in Django?

About an year ago I’ve had the same question. Checked about a dozen solutions and finally narrowed up to johnny-cache and django-cache-machine. Used the last one for no reason, both are stable and good enough.

I’ve just gone through this same consideration, and settled on django-cache-machine, because it supports django 1.5 currently (Summer 2013), and johnny cache has open pull requests for django 1.5 support that have not been merged in. YMMV.
