ActiveRecord basics boilerplate

This is a minimalist implementation of ActiveRecord with one Restaurant model to live-code a demo for @LeWagon students, part of Karr examples, working with Sinatra.

• clone the repo
• run rake db:create to create your db
• run your migrations with rake db:migrate

Now you can play with the Restaurant model:

rake console

Here are some commands you can run in the console:

restaurant = Restaurant.new(name: "La Tour d'Argent", address: "15 Quai de la Tournelle, 75005 Paris")
restaurant.persisted?
# => false
restaurant.id
# => nil
restaurant.save
restaurant.id
# => 1

To launch a Sinatra server just run this and open a web browser at http://localhost:4567:

bundle exec ruby app.rb

Enjoy!
