How can i create an incremental addition of other values in a database
table and sum them up in one column? Is there a way to sum() the wanted
values in one column to create a wanted database value total like i
attempted in the *TOTAL* field in the below code example? I tried something
like the code below but of-course it didn't work, so i was wondering if
there is a way to achieve something like this.
db.define_table('addThem',
Field('quantity', 'integer'),
Field('price', 'float'),
Field('totalPrice', compute=lambda r: r['price']* r[
'quantity']),
*Field('Total', writable=False, compute=lambda r: (r['totalPrice']).sum()))*
