It looks like there is support for groupby in SQLFORM.grid which is what
you'd need to build the proper SQL statement.
I haven't tried this with web2py. If I were, I'd try adding a groupby
clause and a list of fields that include your sum field. Something like
this (not tested)
payments_sum_field = db.payments.amount.sum()
SQLFORM.grid(db.payments, fields=[db.payments.field_1, db.payments.field_2,
payments_sum_field], groupby=[db.payments.field_1, db.payments.field_2])
FWIW - I just submitted a PR for py4web to do exactly what you're talking
about. Looking at the code in web2py for groupby I see that I can improve
what I'd submitted so far.
