I have order item collection
with quantity field
, and total price field
.
When user press add button to add more of the order item, quantity field
is set to be updated as current order item quantity+1
Total price field is set as (current order item quantity+1)Xproduct price
Reverse is with minus when reducing the order item.
The problem is when pressed add button and minus button one after another frequently, the calculation confuses.
I think updating the fields at the same time fails.
