Hello list,
Originally, afaik, the modules in app/helpers are, by convention, only
meant
to be used as view helpers. With time, however, we ended up by only
calling
them helpers, which can cause some confusion and misconception, since
helpers by itself are not attached to the view layer only. The other day
I’ve seen a very interesting use of helper folder organization. Instead
of
putting a rb file in lib, plugins or whatever, my co-worker has created
a
sorthelper and has put it into app/helpers. Then, he included it in the
controller with include, so, a controller helper. I know it’s not a big
deal, but we have been so used to assign the files/modules in
app/helpers to
the view layer that it catched my attention and I though I would share
maybe helpers/ could also be used for little “model helpers”?. Maybe I’m
going too far here 
– Of course, any insights appreciated
Marcelo.
