I have a fairly straight forward table, and a fairly easy db query: db(db.segment.parent == request.vars.id).select()
For my use case, this returns a Rows object of 3 to 10 Row objects, and I do some simple calculations. for row in rows: if row.x: term1 = row.term if row.y: term2 = row.term return dict(rows=rows, mycalc = calc(term1,term2)) (ok, x is really "isstart" and y is "isstop", flags to mark endpoints, but that's being overly specific) I'd also like to compute a delta between the row.term value of each row and it's predecessor (by data entry convention, the table is ordered by id). So the 2 questions are: - can you tell the index in rows of the row you are working on? (I guess this is a Python question, not just web2py). In js, the map and reduce functions know the index in the array they have as input; is something similar available in a Python iteration? - can you add fields to a Row object, or to the parent Rows object, and have the view display it, or is a virtual field definition needed? Thanks.
