In my project, I have
class ApplicationController < ActionController::Base
helper :all
end
module ApplicationHelper
def use_module
### ssss
end
end
class B < ApplicationController
def efd
call_private()
end
private
def call_private()
use_module()
end
end
When I call B::efd(), an error return saying ''use_module()'' is
undefined !!
I was wonderring why ''helper :all'' in my application.rb is not
working
at all.
Then I find that this method is depend on ''HELPERS_DIR''
variable.
However, when I type this ''HELPERS_DIR'' in console, it shows
''uninitialized constant'' error.
Does anyone has the same problem?

But sometimes, we need some methods that both used in view and controller. Where do you suggest to put them in?

ok, I see. Thank you. I just think that "a module that both include in a controller and a helper" is a little bit complicated then just write that method in helper and make controller can access it, in the case that the number of this kind of methods is not a big one. Emm, maybe this is not the correct ruby way of doing things. And maybe I should re-orgnize my app structure like your suggestion. Thank you.
