[web2py] Re: Creating a sums value from a column on an SQLFORM.grid

2022-04-07 Thread Jim S
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.

[web2py] Creating a sums value from a column on an SQLFORM.grid

2022-04-07 Thread mostwanted
Hi guys, I was wondering if i could create a sums column on an SQLFORM.grid 
so that every search that's made produces a sums value, something like this:






*def payments():grid = SQLFORM.grid(db.payments, args=[db.payments])
if grid.process().accepted:query=("#Search queries of the 
SQLFORMgrid")amount = 
db(query).select((db.payments.amount).sum().with_alias('total'))return 
locals()*

Whats possible and whats not?

Regards;
