using helper methods in email templates

hi

I'm creating an template for an html email. My own helper method 'format_price' is not accepted, but it works in some other templates.

application_helper.rb:

# Methods added to this helper will be available to all templates in the application. module ApplicationHelper   def format_price(amount)     euro, cents = amount.divmod(100)     sprintf("EUR %d,%02d" , euro, cents)   end end

order_mailer.rb:

class OrderMailer < ActionMailer::Base   def confirmation(order)     @subject = ''     @body = { :order => order }     @recipients = order.customer.email     @from = "my_email@gmx.net"     @sent_on = Time.now     @headers = {}   end end

private method in the controller:

  def confirm_order(order)     email = OrderMailer.create_confirmation(order) # line 185     email.set_content_type("text/html")     render(:text => "<pre>" + email.encoded + "</pre>" )   end

the error message:

NoMethodError in Cart_and_orders#new_order Showing app/views/order_mailer/confirmation.rhtml where line #23 raised:

undefined method `format_price' for #<ActionView::Base:0x47ca250>

Add a reference to your helper in your OrderMailer ActionMailer class, like this:

helper :application

That should solve your problem (at least this is what I do to fix it).
