Hi,

I am not able to access application\_helper methods in my mailer  
templates.  
It throws out error saying method not defined. I was assuming all  
templates  
under views should have access to application helper methods, but it is  
not  
the case. Any solution?

You can always put the methods in config/environment.rb.

Add helper:application to the top of your Mailer class

for example:

class MessagingNotifier \< ActionMailer::Base  
helper :application

…  
end
