How to generate urls for ActionMailer emails

November 13th, 2007
This is a little bit tricky, but I've found an solution in the comments from other article on this problem. First we need to set default_url_options for ActionMailer::Base. This can be done with before_filter method in ApplicationController

class ApplicationController < ActionController::Base
  before_filter :set_default_url_options_for_mailers

  def set_default_url_options_for_mailers
    ActionMailer::Base.default_url_options[:host] = request.host_with_port
  end

end
Now we can generate the url in the mailer model

  def email_confirmation(user)
    recipients user.email
    from  "example.com  <no-reply@example.com>"
    subject "Confirm your email address"
    content_type "text/html"

    body :user => user, :activation_page => url_for(:controller => "main", :action => 
    'activate', :only_path => false)
  end
