Error Creating Helper Subdirectories

#3334

Scenario

I'm running Rails 2.3.4

I have a helper for Tasks that's too cumbersome to manage. To solve the problem I create a subdirectory called 'tasks' and create helper files such as new_helper.rb, edit_helper.rb and etc..

Problem

When I start my app I get the following error

Expected /directory_to_rails_app/app/helpers/tasks/new_helper.rb to define Tasks::NewHelper

I have defined Tasks::NewHelper in a subdirectory called tasks.

Oberservations, and Quick Fixes

I think the problem has to do with having a helper named 'tasks_helper.rb' and having a subdirectory named 'tasks' at the same time.

While still having tasks_helper.rb and renaming subdirectory to anything else such as 'rockets', Rockets:NewHelper, there's no longer an error.

OR

Removing the tasks_helper.rb will also solve the problem, allowing you to have the subdirectory 'tasks'.

    Hello Andrew,

    I believe the issue you may be seeing is that task is a reserved word in Rails (http://wiki.rubyonrails.org/rails/pages/reservedwords). Tasks::NewHelper seems to indicate that you have a class called Task? Due to the age of this ticket I am going to go ahead and close it out, but if you need further help on it, feel free to update it so we can help.

./script/server:3

    Dunno why but I feel somebody gonna say i'm not up to date...

    Anyway I checked that the file really exists using ls on "error given path".
    The name is not evolving in this bug cause If I erase articles_helper.rb then the same error appears with the sub folder next helper file.

    I stop to use helper :all for now cause I have plenty helpers.
    However this a real trouble.
    I began to get this error yesterday but strangely disappears without doing anything.
    Probably because of I let working the same mongrel all the time.
    But today I relaunched the ./script/server and the error stay.

    My app doesn't use any special tricks.
    I dunno if Routes are evolved in :all loading process but my app does like this :

    ActionController::Routing::Routes.draw do |map|
    map.namespace "backoffice", :path_prefix => "dashboard" do |back|

    back.namespace "content" do |content|
  content.resources :articles
  content.resources :feeds
  content.resources :pages
  etc

    Hope it could help or be enough to reproduce the bug.
