My code sums up the number of certain products (in the Contact module). In the Form View everything is simply summed up by record.
For example, in Contact A I have 20 apples and 20 bananas. I therefore have 40 fruits.
In contact B I have 100 apples and 500 bananas, so I have 600 fruits.
My problem is that in the Tree View all fruits of all contacts are added up - i.e. in the Tree View there are 640 fruits for contact A and 640 fruits for contact B.
sum_fruits = 0
for amount in self.fruits_in_use_ids:
sum_fruits += amount.fruits_amount
self.sum_fruits_in_use = sum_fruits
I wish you a pleasant Sunday!
