Best practices to avoid data inconsistency
I was wondering, how do I best prevent data inconsistency errors? As far as I can tell, I haven't been doing anything crazy. Yet, already two inconsistency problems have occurred. (see http://askbot.org/en/question/338/error-asking-questions-with-multiple-tags)
My additional problem was where my superuser suddenly could not view any questions+replies without an internal server error ... It turned out that I had to confirm his email subscription settings (manually -- the add_missing_subscriptions management command did not work; perhaps there is a bug where it does not address superusers or the original user?).
Thank you again for your help so far! If you have any best practices to avoid inconsistency errors I would be grateful.
