I use rails-3.0.0.beta3 and ruby-1.9.2-preview3.
I have defined some new methods in the application_controller.rb, and
need to test them in the consle.
If I changed some codes in the application_controller.rb.
I should always restart the console.
I have tried to use 'reload!' command, just dosen't work.
And then I use "require 'applicatioin.rb'",
still dosen't work.
