Problem with ar_mailer

Hi guys, I'm running a strange problem sending emails. Basicly I'm getting this exception:

ArgumentError (wrong number of arguments (1 for 0)): /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/ base.rb:642:in `initialize' /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/ base.rb:642:in `new' /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.1/lib/active_record/ base.rb:642:in `create' /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ ar_mailer.rb:92:in `perform_delivery_activerecord' /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ ar_mailer.rb:91:in `each' /usr/lib/ruby/gems/1.8/gems/ar_mailer-1.3.1/lib/action_mailer/ ar_mailer.rb:91:in `perform_delivery_activerecord' /usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/ base.rb:508:in `__send__' /usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/ base.rb:508:in `deliver!' /usr/lib/ruby/gems/1.8/gems/actionmailer-2.1.1/lib/action_mailer/ base.rb:383:in `method_missing' /app/controllers/web_reservations_controller.rb:29:in `test_email' In my web_reservations_controller I have a simply method calling

TestMailer.deliver_send_email And my TesMailer is something like:

class TestMailer < ActionMailer::ARMailer   def send_email     @recipients = "roberto.druetto@gmail.com"     @from = "roberto.druetto@gmail.com"     @subject = "TEST MAIL SUBJECT"     @body = "<br>TEST MAIL MESSAGE"     @content_type = "text/html"   end end

Do you have any idea?

Thanks! Roberto
