This is probably a stupid question, can you have a function available to multiple controllers?
I have 2 controllers
class C1Controller < ActionController::Base
def add(input_value)
@output_value = input_value * 2
end
end
now I would like to use this add function in another controller like so
class C2Controller < ActionController::Base
@new_value = add(2)
end
Define that function in
app/controllers/application_controller.rb, and it will be available in all controllers.
