Windows Rails 3 Errno::ECONNABORTED & Authlogic not working properly & Development 500 error

Question

I'm developing rails app and everything was working fine, but now it started bugging. I have implemented ActionMailer with Authlogic perishable token and now, everytime I try to access UsersController#show it only show me Error 500.

We're sorry, but something went wrong.

and in Server Console

Started GET "/users/1" for 127.0.0.1 at 2012-10-06 13:04:46 +0200
Processing by UsersController#show as HTML
  Parameters: {"id"=>"1"}
  User Load (2.0ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 LIMIT 1
   (1.0ms)  BEGIN
   (1.0ms)  UPDATE `users` SET `last_request_at` = '2012-10-06 11:04:46', `perishable_token` = 'eFBAhfqGX2p04ZfYGb9w', `updated_at` = '2012-10-06 11:04:46' WHERE `users`.`id` = 1
   (3.0ms)  COMMIT
  User Load (1.0ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 LIMIT 1
  Rendered users/show.html.erb within layouts/application (99.0ms)
Completed 500 Internal Server Error in 169ms

development.log is empty. Also when I restart server, my session doesn't expire, so I stay logged after restart. After some time i found that sometime server throws this error

I have tried to work with rails/console everything worked fine. I run out of options and I'm stuck. I would appreciate any help.

Answer 1

The problem was in error encoding in models file. I'm using UTF-8 (for latin2 characters) and I need to add this at the start of every file where I want to use diacritic

#encoding: utf-8

Unfortunately I don't know any better way. If I will use diacritic in a file without encoding set, rails will throw error about invalid multibyte char (US-ASCII). So UsersController#show uses a user.rb method that uses report.rb method. There was diacritic in method.rb file, but I forgot to add encoding line. Somehow Ruby on Rails couldn't handle that error. and it result into 500 Internal Error
