Hi,
I am quite new to ruby and ruby on rails. I am trying to user helper
module in my controller but fail :( I added languages_helper.rb file
to
helpers directory in my RoR app. The file looks like this:
module LanguagesHelper
def LanguagesHelper.sort_to_first(langs, lang)
...my secret method here...
end
end
Then I want to use it in LanguagesController. I put
require "languages_helper"
right in the beginning of the class body, and then in one of
controller''s methods I try to do
ordered_langs = LanguagesHelper.sort_to_first(all_langs, lang)
When while browsing I come to this place in my browser, there is a
message:
undefined method `sort_to_first'' for LanguagesHelper:Module
What is wrong?
Best regards
Pawel Stawicki

> require "languages_helper" > ordered_langs = LanguagesHelper.sort_to_first(all_langs, lang) > undefined method `sort_to_first'' for LanguagesHelper:Modulei believe the error appears because the LanguageHelper isn''t included correctly and so the method isn''t actually embedded in the controller; did you add ''include LanguagesHelper'' ? (this mixes it in) also, you can put in modules in the RAILS_ROOT/lib folder and require them just as easily (it doesn''t have to be a ''helper'') -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

> i believe the error appears because the LanguageHelper isn''t included > correctly and so the method isn''t actually embedded in the controller;I think it is included correctly, because in error message there is undefined method, but there is nothing like "unknown module LanguagesHelper". I think module is available, but method is not. (But of course I can be wrong).> did you add > > ''include LanguagesHelper'' ? (this mixes it in)I tried this too, but it didn''t help :(> also, you can put in modules in the RAILS_ROOT/lib folder and require > them just as easily (it doesn''t have to be a ''helper'')I prefer to have it in helper, just for this app. Thanks anyway Regards Paweł Stawicki -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I think module is available, but method is not. (But > of course I can be wrong)...i''m not sure about this, but if you change module LanguagesHelper def LanguagesHelper.sort_to_first(langs, lang) ...my secret method here... end end to module LanguagesHelper def sort_to_first(langs, lang) ...my secret method here... end end and then in the controller, just put the method name (without prepending it to LanguageHelper) like ordered_langs = sort_to_first(all_langs, lang) i''ve had something similar, and i believe this worked for me. what is the outcome if you use the above? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
