Caching isn't the issue here, it's a matter of writing the queries properly. Yes, select_related will help. But you can't expect the tutorial to explain these concepts - it's supposed to be a very basic introduction to using Django, and doesn't go into detail. The full explanation of how to make queries is in the actual documentation. -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.
