I am trying to run ar\_mailer for mass mailings, but I can´t get my  
server started after adding the sentence  
require ‘action\_mailer/ar\_mailer’  
in environment.rb

I am using Windows XP, Ruby 1.8.6, and Rails 1.2.3/Edge Rails.  
This is the error I get

\*\* Starting Mongrel listening at 0.0.0.0:3000

I have the same error, even trying to do that require in irb.

Does this gem works with Windows XP?

Thanks in advance.

Well. It seems that the problem has nothing to do with windows XP.  
Maybe the problem is with Edge Rails.  
Now, I have moved the sentence require ‘action\_mailer/ar\_mailer’ to  
config/environments/\*.rb instead of config/environment.rb and the server  
starts.  
But now, as soon as I change the base class of the mailer classes to  
ActionMailer::ARMailer the template file could not be finded by  
ActionVier.

This is the error I get. ‘prueba’ is the name of template in this case.

Couldn’t find template file for prueba in “/ventas\_mailer”

vendor/rails/actionpack/lib/action\_view/base.rb:282:in `render_file' vendor/rails/actionpack/lib/action_view/base.rb:318:in`render’

-e:2

Any help?

I have the problem like it before. What I do is :

1. Re-install Gem
2. do script/mailer again, but do not replace model
3. restart my server
4. Back working 🙂

Enjoy,
