ruby on rails - The scope of custom helper -

-

i have defined helper function in helper:

module carshelper    def my_helper     ...   end  end

but can neither used it(my_helper) in carscontroller nor in car model, custom helper can used in view?

helpers views. can include them in controllers well. add 

helper :cars

to controller. (docs)

models out of scope helpers. use class or instance methods in there instead.
