I have followed book until chapter 5 finished and it’s working OK in my linux workstation
when I push to Heroku, all data pushed correctly but when I try to open Heroku (http://vivid-sky-685.heroku.com)

I get a 404 message.

The page you were looking for doesn’t exist.
You may have mistyped the address or the page may have moved.

Below is my Gemfile for application

source 'http://rubygems.org'
gem 'rails', '3.0.5'
gem 'sqlite3'

group :development do
  gem 'rspec-rails', '2.5.0'
end

group :test do
  gem 'rspec', '2.5.0'
  gem 'webrat', '0.7.1'
  gem 'spork', '0.9.0.rc4'
end

gem 'rake','~> 0.8.7'

Any ideas what could be going wrong?

@odin here is my heroku logs , thanks

    I got the same problem; however, after changing 1 line code of production.rb located in config/environments/production.rb from

    config.assets.compile = false

    to

    config.assets.compile = true

    commit the new change. Then my sample app works fine on heroku
