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.

Help! ☹

Well Application Controller is a class, so I think you would want to  
do require “ApplicationController”

If that does not work you can always just paste the methods in and  
call them. Kind of hacky but it works.

How are you trying to run your controller methods in the console?  
What’s the exact syntax you’re using? Normally, you can’t do this  
easily…
