  class ApplicationMailer < ActionMailer::Base
    def post_notification(recipients, post)
      @recipients   = recipients
      @subject      = "[#{post.account.name} #{post.title}]"
      @body["post"] = post
      @from         = post.author.email_address_with_name
    end

    def comment_notification(recipient, comment)
      @recipients      = recipient.email_address_with_name
      @subject         = "[#{comment.post.project.client.firm.account.name}]" +
                         " Re: #{comment.post.title}"
      @body["comment"] = comment
      @from            = comment.author.email_address_with_name
      @sent_on         = comment.posted_on
    end
  end

  # After this post_notification will look for "templates/application_mailer/post_notification.rhtml"
  ApplicationMailer.template_root = "templates"

  ApplicationMailer.create_comment_notification(david, hello_world)  # => a tmail object
  ApplicationMailer.deliver_comment_notification(david, hello_world) # sends the email
