Hi!

Ruby files from the lib directory don’t automaticaly loaded/required.  
I tried adding string:

config.autoload\_paths += %W(#{config.root}/lib)

to my application.rb file but it doesn’t work too.

Second problem with ‘require’ files (libs or modules). At the first  
request to the application necessary files includes. But at the  
following requests it doesn’t occur. Partially this problem can be  
decided if to use ‘include’ instead ‘require’ but it’s bad solution ☹
