How to use the “number_to_currency” helper method in the model rather than view?

Question

I would like to use to_dollar method in my model like this:

module JobsHelper      
  def to_dollar(amount)
    if amount < 0
      number_to_cur

Piggybacking off of @fguillen's response, I wanted to override the number_to_currency method in my ApplicationHelper module so that if the value was 0 or blank that it would output a dash instead.

Here's my code in case you guys would find something like this useful:

module ApplicationHelper
  def number_to_currency(value)
    if value == 0 or value.blank?
      raw "–"
    else
      ActionController::Base.helpers.number_to_currency(value)
    end
  end
end
