read the source.

script/server loads the Rails environment boot file:  
require File.dirname( **FILE** ) + ‘/…/config/boot’

then requires a file from the Rails gem:  
require ‘commands/server’

locate your rails gem install and read server.rb, should be in  
ruby/lib/gems/1.8/gems/rails-x.x.x/lib/commands/server.rb

Assuming you are running in development mode and that you haven’t  
fiddled with the config.cache\_classes settings, one way of messing up  
auto reloading is by using require to require stuff that rails is  
capable of loading automatically.

Thanks for your answer Fred…

I am in development environment, I have config.cache\_classes =\* false\*  
(in  
my development.rb file)  
In the environment.rb file i have require  
File.join(File.dirname(_ **FILE** _  
), ‘boot’).  
I try by instancing load\_once\_path:  
Dependencies.load\_once\_path?(RAILS\_ROOT)  
in my environment.rb  
But does not work. I am not an ruby expert.

Can you explain me what can I do?

Thank you very much.  
Margareth

Hi Fred… Know the ruby code reload without restart the server but views  
do  
not.

If you are using require to load any of your application’s classes,  
then don’t
