I believe that doing [1:3] and [3:10] separately will result in two database queries - it evaluates on the the slice. If you wanted to curl that into one call, then it would be up to you to do your original slice as [1:10] and then pull out the pieces for your internal loops as needed.

Hi all, I'm a little confused about when querysets are evaluated. Supposing that my generic is passed a queryset = entries where entires = Entry.objects.all(), would the queryset be evaluated when I first start a for loop in the template? What if I want to slice it in two for loops? For example, if I have [1:3] and [3:10]. Would that actually be two separate database calls with limit 3 and limit 10, or is Django smart enough to recognize and slice only the combined list of [1:10]? Also, if there's someplace where evaluation is explained in more detail, I'd appreciate it if someone could point me that way. I foudn a little bit about when it gets evaluated in the docs for the DB API, but it was fairly light on the details. Thanks! --- David Zhou [EMAIL PROTECTED] >
