Is it possible to have method(s) in application\_helper.rb available for controllers, just like for views? Actually my method is current\_user too 😃 and looks pretty similar, but I'd like it in application\_helper.rb...

Hi James,

instead of mixin in a whole helper module I'd declare the Helper method as module\_function like:

module SomeHelper &nbsp;&nbsp;1000.times do |index| &nbsp;&nbsp;&nbsp;&nbsp;define\_method(:"waste\_#{index}") { index \*\* 2 } &nbsp;&nbsp;end &nbsp;&nbsp;def some\_method(\*some\_args) &nbsp;&nbsp;&nbsp;&nbsp;some\_args.inspect &nbsp;&nbsp;end

&nbsp;&nbsp;module\_function :some\_method end

In your controller you can then do:

class Somes \< ApplicationController &nbsp;&nbsp;def some\_action &nbsp;&nbsp;&nbsp;&nbsp;SomeHelper.some\_method &nbsp;&nbsp;end end

Don't pollute your controller... 😉

Regards Florian
