Re: Looking for a way to detect changes in database records with low storage footprint

You could grab the __dict__ of the instance and use that.

import hashlib

hash = hashlib.md5()
hash.update(str(MyModel.objects.get(pk = 1).__dict__))
hash.digest()

Thanks, but *how* can I create a hash from a database object in Django - is there a generic method to iterate over all (or only specific) fields and get a hash value?

A hash should work fine. Alternatively, you could diff the two records,
using something like difflib: http://docs.python.org/2/library/difflib.html
