Just recently installed Ruby for the purpose of developing extensions  
for SpiceWorks. However, this is my first ever experience with Ruby  
since its update to its new form (last time touched was at least 3 years  
ago when there’s no such thing as Webrick server). What I had noticed  
was, when I start the Webrick server, if I generate a new controller, I  
would receive a routing error until I restart the Webrick server. So  
that means for every test of modification I would need to restart the  
Webrick server, is that true? If it is, it would seem to be very  
tedious. Thanks.

UPDATE: Something I found really odd is that without restarting server,  
the new controller would only take effect after a while. Maybe I have  
done something during this time, but I don’t know. Does anyone what’s  
the possible problem?

Webrick has been around longer than 3 years, but I’m guessing this is  
your first time with Rails. (I’m assuming that SpiceWorks is still  
Rails-based.)

You might want to try seeking more targeted guidance from the Rails  
list.

It sounds like you may be starting the server with the Rails  
environment (RAILS\_ENV) set to production rather than development.

"Development Mode  
config.cache\_classes = false

Production Mode  
config.cache\_classes = true"

“if config.cache\_classes is true (which it is in production) then all  
of your models, controllers etc are loaded up as part of application  
initialization”

Thanks for the clarification with Webrick server. I guess last time when  
I tried Rails it had Webrick but I wasn’t aware of it.

Also, for the environment variable, I checked it and it seemed that my  
application is already running under development mode. So that rules out  
this possibility. Could there be other problems?

PS. I’m running all this on Win 7.
