Another newbie question: I want to keep business logic out of my
controller. For example I had a routine that did a slightly
complicated computation and it didn't seem to belong in the
controller. But the calculation has nothing to do with display per-se.
It takes an integer in and returns a different integer.
So I thought to put it in the corresponding helper. Is that the best
Because I note that helpers are not automatically 'included' in the
corresponding controller. I had to add an 'include' to the controller
which seemed a bit lame.
