Rails vs Sinatra

Note: Overview of creating a new rails application, point out comparisions to sinatra as you go

• (http://guides.rubyonrails.org/getting_started.html)[http://guides.rubyonrails.org/getting_started.html]
• rails command line
• rails new options

Creating a new Rails Application

$ rails new blog -d foo

• databases - prefer postgresql

$ rails new blog -d postgresql -T

Walkthrough Generated Files

$ cd blog
$ tree -d

• Lots of stuff!
• Find correct version: (http://guides.rubyonrails.org/)[http://guides.rubyonrails.org/]

Starting a Rails Application

$ rails s

OOPS :) We need to do a little more

Initializing the Database

$ cat Rakefile
$ rake -T

$ rake db:create

$ rails s
$ open http://localhost:3000/

• TADA! - (Hopefully)

Building Your Application

Routing

• $ cat config/routes.rb
• $ rake routes

Models

• $ rails generate model Article title body:text
• $ rake db:migrate
• $ rails console (or rails c)
• $ rails db - can fire up psql
• > Article.create!(:title => 'Hello World', :body => 'The answer is 42')

Controllers

• rails g controller articles index
• But that generates some things we don't want....
• rails g controller articles index --no-helper --no-assets
• redirect_to instead of Sinatra's redirect

$ rails s
$ open http://localhost:3000/articles/index

Routing Revisited

• $ rake routes

Views

• ERB the same as we did in Sinatra.
• Edit the controller and view to show the article created in the console

And Go Do It!

• Review Routing Docs - http://guides.rubyonrails.org/routing.html
• View Helpers link_to
• Review layouts
• Add CSS in the assets folder
• RSpec
