Rails for Zombies: Parts 1 & 2
summary
Creates a small app called Twitter for zombies and walks through the exact commands and files used: rails new TwitterForZombies, rails g scaffold zombie name:string bio:text age:integer, then runs rake db:migrate and shows schema.rb, timestamps, and the SQL emitted in the console. Covers CRUD with ActiveRecord (find, create, update, destroy), migration patterns (change vs up/down, add/remove columns), bundler and Gemfile, default SQLite and swapping to MySQL, rake rollback, and hands-on labs to follow along.
