Re: Problem in installing database adapter.

I don't remember how I installed it (mysqldb or python-mysqldb), but assuming that this is the correct module, then it's possible that it's for different Python version that you are actually using. For example, default Python for Ubuntu 8 is, iirc, 2.5.2, while you might be using 2.4 or 2.6 for y

Re: How to restrict True value to only one row in table column

Maybe you can use something like this: http://stackoverflow.com/questions/1346765/unique-constraint-that-allows-empty-values-in-mysql This would probably mean converting is_master to: is_master = models.BooleanField(null=True, blank=True, unique=True) - and possibly overriding save to convert

Re: "Lost" sessions

One more thing - out of sudden it turns out that session can be "lost" even if no external redirect is involved. So basically first request, without any session cookie set, seems to have some dummy session id, because only subsequent sessions ids survive. --~--~-~--~~~-
