Hi,

I’m trying to send some emails with the same formatting as my pages & I  
can’t seem to access my display routines in application\_helper.rb. I’m  
trying a hack to bypass this.

At the top of my ActionMailer notifier script I’ve included  
application\_helper.rb - my understanding is that this should arrive as a  
module and should be able to be used accordingly.

\<% require File.dirname( **FILE** ) +  
‘/…/…/helpers/application\_helper.rb’ %\>  
\<% display\_money = ApplicationHelper.display\_money -%\>

However I get a compile error:

undefined method `display\_money’ for ApplicationHelper:Module

The ‘display\_money’ routine does exist in application\_helper.rb & is  
working happily when rendering my pages.

Any ideas on how I can overcome this?

I think you can make the application helper available by adding:

helper :application

to the mailer model.

Indeed you can - works great now.

Many thanks.
