How can I get sub-totalling in tables? I have an ActiveResource model which gets it's data from a legacy Windows app via REST. The records are ordered by date. I need to display subtotals by week number. It looks like I'll have to code something, which isn't a problem, but this is such a common pattern someone must have done something before me. Any clues?

Have you looked at the group_by method of Enumerable? "Collect an enumerable into sets, grouped by the result of a block. Useful, for example, for grouping records by date." On May 19, 6:57 am, John Small <rails-mailing-l...@andreas-s.net>
