Edit config/environment.rb:

Uncomment config.load_path and add the path that contains your helper.
E.g., if your helper is in dir src/rails/helpers and your rails app is
called plan and is located in src/plan, add this to environment.rb:

  config.load_paths += %W( #{RAILS_ROOT}/extras
                           #{RAILS_ROOT}/../rails/helpers )

Create a file in src/rails/helpers called (for example) formatting_helper.rb:

module FormattingHelper

  def format_time(time, format_str = "%m/%d/%Y<br />%I:%M:%S
%p")
    time.strftime(format_str)
  end
end


Now in your controller add

  helper :formatting


In your views you can access format_time. E.g.:

<p>Started on: <%= format_time @task.created_at %></p>

Hope this helps.

Hi, 

thanks you very much for the information, however, I
have tried the cmd "config.load_path", but it doesn''t
work, I have felling that rails doesn''t not recognized
the path that I added. 

actually, the extra helper modules is outside of the
application rails file structure. (I''m using linux)

the extra helpers is stored at /opt/web/extra/helpers/
so I added the following line at the
config/environment.rb

config.load_paths += %W("/opt/web/extra/helpers/")
and in my controller I added 

helper :extra (which the module name is extraHelper,
and the filename is extra_helper.rb)

rails seems to ignore that. when I try to shoe the
webpage, I got error that rails is not able to locate
the extra_helper in /app/helpers/

How can I tell rails that it should look in
/opt/web/extra/helpers/ instead of /app/helpers/?

Thanks you very much

Saiho
