[Ruby] ApplicationHelper methods in ActionMailer templates

[Scott Windsor]

I remember it failing quite ungracefully, and was also frustrated by it
until I found the documentation.  It would be really nice to have UrlWriting
included by default for your mailers, but I understand the problem of not
knowing which hostname to use.

Here's what I've been adding in my environment.rb (or initializers for rails
2).

require 'socket'
class ActionMailer::Base
  include ActionController::UrlWriter
  # override this for production!
  default_url_options[:host] = Socket.gethostname
  default_url_options[:port] = 3000
end

This gives you the hostname of your machine by default.  This works great
for testing a development environment locally but *not at all* what you want
for production.
