Access helpers from mailer?

Question

I have trying to access helper methods from a rails 3 mailer in order to access the current user for the session.

I put the helper :application in my mailer class,

I'm not sure exactly what you are doing here, but when I want to access current_user from a mailer, I make a mailer method that I pass the user to as an argument:

class CommentMailer < ActionMailer::Base
  default :from => "Andre Fournier "

  def blog_comment(user)
    @recipients                   = user.email
    @from                         = "andre@gfournier.com"
    @sent_on                      = Time.now
    @timestamp                    = Time.now
    @user                         = user
  end
end

With the above, @user, as well as all the other instance variables, are accessible from inside the mailer views ./views/comment_mailer/blog_comment.html.erb and ./views/comment_mailer/blog_comment.text.erb

Separately, you can make a helper called

comment_mailer_helper.rb

and put into that helper any methods that you want to be available to your mailer's views. This seems to me more like what you might want, regarding helpers, because helpers are designed to help views, whereas a mailer is analogous to a controller.
