    In django, this might look something like this:

      s = Stories.objects.order_by('-num_votes')[0]
    • pg 16 years ago

      The query I did was much more complicated. The Arc equivalent of yours is

          ((sort (compare > score) stories*) 0)
      • ivankirigin 16 years ago

        Just in case it isn't clear, that order_by actually digs into the database layer to do the sorting there. It's a query that returns an iterator that gives you stories in that order one at a time.

        To sort an existing list, over a particular member, it would be

          Stories.sort( key = lambda x: x.score )

        That lambda has certainly confused a lot of people I know. Probably because they used the word "lambda" and not "function".
