Hi Jury, As the release notes indicate, there was some conversion code in place to help make this transition; however, that code was removed in the 1.4 release. This means you have two options:
1) Run your site for a while on Django 1.3 before upgrading to 1.5, where "a while" is the length of SESSION_COOKIE_AGE. This will give enough time to ensure that old cookies are updated to the new signed format. 2) Write a custom session backend that re-introduces the old fallback. If you get the 1.3 codebase, the conversion code is all contained in the decode() method of django.contrib.sessions.backends.base.py; it's a relatively simple fallback mechanism which shouldn't be too hard to add back to a custom session backend. Once SESSION_COOKIE_AGE has expired, you'll be able to remove this custom backend, and go back to the normal session backends. Yours, Russ Magee %-) On Mon, Dec 17, 2012 at 12:28 PM, Jury Gerasimov <j...@softshape.com> wrote: > Hi all, > > we're migrating from Django 1.2 to 1.5, and we've fixed all the > compatibility issues except one.
