Tinder Pizza Sinatra Demo

bundle exec ruby tinderpizza.rb 

First Lecture

• What is rack?
• We're using sinatra
• bundle init
• What's in the Gemfile
• bundle install
• Blocks must return a string
• Default status code 200 and content type text/html
• bundle exec ruby tinderpizza.rb
• views folder
• views/layout.erb

Second Lecture Prep

This is slightly different than the Sinatra Skeleton App so you can compare. I'm using sinatra-activerecord gem to save me some steps. Note; the rake db:create_migration task is different from your code. Because I'm using require "sinatra/activerecord/rake" in the Rakefile instead of writing tasks by hand.

• Add gems
  • gem "sinatra-activerecord"
  • gem "sqlite3" - don't need postgres for demo
  • gem "rake"
• Add models directory
• Add models/pizza.rb

class Pizza < ActiveRecord::Base
end

• autoload :Pizza, settings.root + '/models/pizza'
• Add db directory
• Added Rakefile for db tasks
  • and rake console (handy!)
• Added migration rake db:create_migration NAME=create_pizzas
• Added Validations
• Added db/seeds.rb so rake db:seed works
• Added footer and nav to layout
• Added static /about_us route
• Added controllers/pizza_controller.rb

Nested Routes

• Toppings Belong to Pizzas
• controlers/topping_controller.rb
• views/toppings

Secret Random Keys

• models/pizza.rb - before_create
• db/migrate/XXX_add_secret_key_to_pizzas.rb

2.1.3.A Controller Testing

• RSpec to test Sinatra
• Need to support different databases for testing and development
  • Use RACK_ENV
  • Look at the set :database line in tinderpizza.rb
  • RACK_ENV=test rake db:create
  • RACK_ENV=test rake db:migrate
• Create specs in folders underneath ./spec folder
• bundle exec rspec
