Here's a standard route that maps /about to the store controller's about action:

get 'about', to: 'store#about'

root to: 'store#home'

Multiple standard routes can be created in one line:

git and Heroku

Add files to git

  • git add . - Adds everything to git.
  • git commit -m "message about feature" - Commits your changes to git.


  • git push heroku master - pushed your updated code to Heroku.
  • heroku run rake db:migrate - runs database migrations on your Heroku site.
  • heroku run console - run the Rails console on your Heroku app.


A controller controls access to an application and makes data available to the view.

rails g controller Store home - generates a Store controller with a home action and associated files.

class StoreController < ApplicationController
  def home
    @title = "Automated Store"

@title is now available for the view file to use (home.html.erb).

Usually, the controller makes data from the model available to the view. For example:

 def index
    @products = Product.all 


The view folders consist of html.erb page templates that are processed and sent to the user. Each template can contain Ruby code to display data from the controller.
