Rails - Dec 2005 - N00B Question: How to access methods in a helper?

Hi,

  I always get the following error when trying to access a helper method.

-->  undefined method `some_helper_method'' for
#<BlogController:0x2706fec>

blog_controller.rb:
class BlogController < ApplicationController
  def index
    render(:text => some_helper_method("x"))
  end
end

blog_helper.rb:
module BlogHelper
  def some_helper_method(text)
    text+="!!!!"
  end
end

(Structure came from script/generate controller Blog)

  On a sidebar ... What I was actually trying is to use textilize, but also
got the same error message. Installing redcloth as gem didn''t help,
neither
adding require_gem "RedCloth" to environment.rb.

  ???

  Any idea what I do wrong?

Cheers,
Mariano

Helpers are not available in controllers.  Try this instead:

def index
  render :inline => "<%= some_helper_method(''x'')
%>"
end

Another possibility is:

def index
  render_text(@template.some_helper_method("x"))
end

More efficient too. But it will not work for helpers that require the 
full view context to run.
