Rails - Apr 2006 - Cannot use view helpers in RJS helpers

Any ideas why I would get an error in a RJS helper on view helpers
such as number_to_currency.

Example:

# my_template.rjs

page.help_me

# my_helper for my_controller

def help_me
 number_to_currency(10)
end

I have also tired page.number_to_currency but that doesn''t work either.


Cheers,
Nicholas

It has to do with the scope of the helper.  The ActionView::Helpers
modules aren''t included into the context the RJS helper method is
executed in.  You can manually include the helpers you want into your
module like so:

module ExpensesHelper
  include ActionView::Helpers::NumberHelper

  def help_me
    number_to_currency(10)
  end
end
