Ruby is a programming language, Rails is a Web Framework built on top of it.

• So, what’s the big deal?
• #1, It’s FUN!
• #2, It’s EASY!
• Standard Setup
• Convention over Configuration
• #3, It’s PRODUCTIVE
• Why should I care?
• Broaden your horizons, become a generalist, rather than a specialist
• Expand your toolbox
• It will make you a better Developer
• What is Ruby?
• Object Oriented
• Dynamically Typed
• More flexible, but less structured
• Don’t see errors at compile time
• Somewhat requires Unit Testing to prevent runtime errors
• Duck Typing
• Comes from “if it walks like a duck, quacks like a duck…”
• The Ruby Language
• .each Method (similar to foreach)
• do –> end
• Everything is an object in Ruby
• next_week = 10.days.from.now
• unless statement
• unless today.is_saturday_or_sunday? <- ? returns a boolean
• if at the end
• puts “blah” if blah
• Strongly typed, but not statically typed
• No diacritic marks ({, ())
• The Rails Framework
• Free and open source web framework
• Does Web applications with a database back-end very well
• It’s a very specific framework
• Uses MVC Framework (Model, View, Controller
• Three Tenets
• Convention over Configuration
• Via scaffolding, can write boilerplate code to get all, get by id, build tables, etc.
• Don’t Repeat Yourself
• Each piece of knowledge should have one and only one place to live
• ActiveRecord
• An object should have the logic to put itself in the database and take itself back out of the database
• RadRails for aptana
• Netbeans IDE
• Create a Rails project in 3 steps
• rails project_name at command line
• Edit yaml file for database setup
• ruby script/server
• MVC
• request comes into controller
• controller looks at the model to pull what it needs
• it then pushes that to the view
• view provides the response
• controllers have actions (which are just methods)
• URL (controller/action/parameters)
• Controller code is written to get data from the model
• Models
• Create a new model at the command prompt (rails generate model modelname)
• Database migration scripts provide information about how to setup and teardown databases
• Free Methods
• find by id
• find by name
• find all
• sort
• Forms
• Scaffolding builds the forms for you
