[Rails] NoMethodError in Weblog#list

[Eric Ocean]

I'm following along the 10 minute intro video (and it's taken _way_  
more than 10 minutes to get halfway through the video :-). I just ran  
the script/new_model Post command, and everything seems to be in order.  
I modified weblog_controller.rb to be:

require 'abstract_application'
require 'weblog_helper'
require 'post'

class WeblogController < AbstractApplicationController
   include WeblogHelper

   scaffold :post
end

When I point my browser to http://blog.ampede.com/weblog/list, I get  
the following error:

  NoMethodError in  Weblog#list

Any ideas on where to go from here? I also updated the database as in  
the video, and my database.yml file is set to

production:
   adapter: mysql
   database: ampede_blog_production
   host: localhost
   username: username
   password: password

test:
   adapter: mysql
   database: ampede_blog_test
   host: localhost
   username: username
   password: password
