pardon me, for not tell obviously about the code that i want to achieve
my objective :
i want to have a grand total of items (sum) that have been in shopping
cart's session, check is the item have a promotion price or not, if have a
promotion price (promotion_price > 0) use promotion price of item * quantity,
if don't have promotion price (promotion_price = 0) use unit price of item
* quantity
in pseudo code :
grand_total = sum(for id, qty in session.order.items():
if db.product(id).promotion_price:
db.product(id).promotion_price*qty
else:
db.product(id).unit_price*qty
)
any idea or suggestion how to achieve pseudo code above in python or web2py
way?
thank you so much
