Hi I am learning rails and have hit a bit of a wall. I have created methods previousley that work fine on a single object. However in my latest project I am trying to calculate the total cost of a group of phonecalls and I am having difficulty creating a method to calculate this. I have a phonecall model and phonecall has a cost attribute.
In my controller I am finding the @phonecalls And in my view I want to say @phoncalls.total_cost However I keep getting an undefined method error. In my phonecall model i am trying to iterate through a block. def total_cost totalcost=0 each do |phonecall| totalcost += phonecall.cost end totalcost end I have tried varios types of blocks, various connertaions of this method and self.each.... but I dont seem to be getting anywhere. I am not sure if this is because of the fact that my syntax is wrong when dealing with a collection of objects as I am in this case. I can iterate through those objects in the view ie for each phonecall in @phonecalls etc and I am getting the correct output o I am happy that the controller code is working fine. Any help would be muchly appreciated as I am struggling to find help in my books and online.
