The problem is that sort() doesn't return anything, it sorts in-place. So you can't chain it, as reverse() acts on the return value of the previous function, which is None. Although I can't understand why you got the error you did, I would expect the error 'NoneType' object has no attribute 'reverse'. -- DR. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Sometimes datetime sometimes date?
sqlite3 I changed the method and it seems to be working now. The code I'm using is: def all_last_updated(self): d = [self.last_updated, self.activity_set.latest ().last_updated] d.sort() d.reverse() return d[0] There seemed to be some problem when chaining sort().reverse() before. Not sure I understand it still and attributing it to me missing something in general but it's working now.
