first rails deploy to heroku

this’s first time I deploy to heroku,. with one page without database

 rails g controller Store index

and delete public/index.html.
root :to => ‘store#index’

I am put in my Gemfile

group :development, :test do
  gem 'sqlite3'
group :production do
  gem 'pg'

and then

 bundle install --without production

Store my Application in git as usual

   $ git init
   $ git add .
   $ git commit -m "init"

deploy my Application in Heroku

   $ heroku login
   $ heroku create
   $ git push heroku master

visit my Application

$ heroku ps:scale web=1
$ heroku ps
$ heroku open

and then, open my App
my first trial

and second time, with several pages and adding the stylesheets (css)
also ‘heroku logs’ is useful for tracing error

In config/application.rb, add

config.assets.initialize_on_precompile = false

second trial
