Hi all, I submitted a patch a couple of days ago that makes it possible to group on multiple fields when using AR calculations (http:// dev.rubyonrails.org/ticket/10771)
Given this table for a Sample model: id year month value 1 2007 3 1 2 2007 3 2 3 2007 4 4 4 2007 4 10 5 2007 5 12 6 2007 5 3 7 2007 5 1 8 2008 1 3 Sample.count(:id, :group => [:year, :month]) and Sample.count(:id, :group => 'year, month') currently fail. The patch makes both work, returning a nested structure like this: [[ 2007, [[3,2], [4,2], [5,3]] ], [ 2008, [[1,1]]]] (the order of nesting is controller by the order of the fields in the group param, of course). I'd love feedback on the implementation. Thanks!
