Running Rails 2.3.5

I am new to Ruby and Rails. From the console I get the following
ThreadError below. Any suggestions are very welcome.

app.get “/slides”
=> 200

app.request.path_parameters
=> {“action”=>“index”, “controller”=>“slides”}

app.get “/slides/1”

Keith,
I too am using the “Up and Running” book and had the same problem.
I googled and found that you can fix this by editing:

config/environments/development.rb

and setting:

config.cache_classes = true

Of course, you’ll want to undo that change as soon as you are done
with the console. Otherwise you’ll need to restart scrip/server every
time you changes one of your class definitions.

For the source of this fix visit:

Enjoy,
Robert
