Alright I am sry for the noob question but this has been driving me up a wall-especially because I got it to work yesterday and I can't remember what I did....

I am just trying to use mysql with rails with a mongrel server. I set up the server fine and can run rails applications that don't need mysql but when I create a project using (for example) rails -d mysql blog and then create some simple controller e.g. ruby script/generate Test then put this code in the controller...

class TestController < ApplicationController
 def index
  render :text => 'WORK'
 end
end

then when I start the server up and open up localhost:3000/test I get the following error:

=> Booting Mongrel
=> Rails 2.3.5 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

In the browser i get a 'We're sorry, but something went wrong'
Does anyone know what I am doing wrong?
