[Rails] actionmailer issues

Nolan,

Why do you use a confirmation_id field as an attr_accessor? Why not juse use 
an association? I can't see an obvious problem with your code, but I do the 
exact same thing, here's how I do it:

class ApplicationMailer < ActionMailer::Base
  @@template_root = "../app/email_templates"

  def verify_notification(user)
    @recipients         = user.email_address
    @subject            = "Account Created"
    @body["first_name"] = user.first_name
    @body["last_name"]  = user.last_name
    @body["validation_key"] = user.validation_keys.build('validation_key' => 
Digest::SHA1.hexdigest(rand.to_s),
                                                         'date_created' => 
Time.now())
    @body["validation_key"].save
    @from               = "webmaster at xxxxxxxx.com"
  end
end

<html>
<p>Dear <%= @first_name %> <%= @last_name %>,</p>

<p>Thank you for registering with xxxxxxxxxxxxxxxx</p>

<p>Please click <a 
href="http://www.xxxxxxxx.com/home_page/validate?validation_key=<%= 
@validation_key.validation_key %>">here</a>\
 to validate your account.</p>

<p>Webmaster</p>
</html>

class ValidationKey < ActiveRecord::Base
  belongs_to :user
end

class HomePageController < AbstractApplicationController
  def validate
    @key = ValidationKey.find_first( ["validation_key = '%s'", 
@params['validation_key']] )
    @key.user.validated = 1
    @key.user.save
    @messages = ["Thank you #{@key.user.login}, you are now authenticated."]
    @key.destroy
    render_action "entry"
  end

If I had to guess I'd say it was something to do with your model. If you 
still have problems try putting inspect methods everywhere for debugging 
output. My code is a little dirty, looking back I'd put the validation key 
generator in its own method.

>    @user.confirmation_id = confirmation.id
>    Accounts.deliver_signup_email_confirm(@user)

> Your account will then be active, and you can log in using the
