Error running ar_sendmail when using Alternate Mail Storage

[ares]

I set another class in initializer and when ar_sendmail is run I got Unhandled exception undefined method `email_class=' for ActionMailer::Base:Class(NoMethodError):

[ares]

I'm using adzap-ar_mailer (2.1.8)

[adzap]

What version of Rails?

[ares]

2.3.5, no easy way to update right now (even to 2.3.6)

Solved!
Problem: ar_sendmail.rb
251 begin
252 require 'config/environment'
253 require 'action_mailer/ar_mailer'
254 rescue LoadError

As you can see config/enviroment is loaded before action mailer actually got email_class accessors. You can add

require 'action_mailer/ar_mailer'

to the first line of your initializer so it gets these methods before you use them. Maybe you could update README.

That require actually seems unnecessary as the gem/plugin should be loaded already after the environment loads. So I am not sure why this can't work without requiring ar_mailer at all.

[ares]

yes, it's strange when I run irb in rails app root and run
require 'config/environment.rb'
ActionMailer::Base.email_class = QueuedEmailMessage
everything seems to work

I don't see why but that require helped. Are you able to reproduce this problem (e.g. on newer version of rails)
