Question

So, I got mailer app/mailers/dynamic_mailer.rb and model app/models/email_message/outgoing.rb. There is method:

class EmailMessage::Outgoing < EmailMessage
...
  def deliver_mail
     l = ::DynamicMailer.email_message(self).deliver!
     Rails.logger.info "SEND MAIL: #{l.inspect}"
     update_attribute(:received_at, Time.now)
  end

Locally (developement env) everything works fine. The problem occurs when I’m deploying app to server (staging env) and trying to send email form there. Delayed job prints:

[Worker(host:rdev pid:2279)] EmailMessage::Outgoing#send_email! 
  failed with NameError: uninitialized constant 
  EmailMessage::Outgoing::DynamicMailer - 11 failed attempts

It looks like a problem with loading classes on server. Removing double colons before class name fails.

Any help will be greatly appreciated.

I just forgot to restart delayed job daemon.

You can do it with capistrano, by adding gem ‘daemons’ to your Gemfile and updating receipes like that: http://cmar.me/2011/02/21/delayed_job-with-rails-3-and-capistrano/
