Total newb here, as I've been working my way threw the tutorial, but
doing my own thing.
I've created a fairly simple app, that has a bunch of items. Each
item has 6-9 fields that have a cost associated with them (db field =
float). Think of each item as a car maintenance log, oil change =
$50.00, tires = 500, breaks = 230 etc.. I want to be able to add up
all the fields associated with the item for a grand total.
I've read a lot and I"m not sure if I'm modifying the model, or coming
up with something fancy in the controller etc..
Any help with my baby steps is much appreciated.
