Piles of notes at Ruby on Rails Notes but some of the stuff there is deprecated. Adding my notes/reminders for 2.0 here.

Application Creation

• creating app is the same
  • rails yourapp
    • using mysql -> rails yourapp --database=mysql yourapp
  • create db
    • via rails
      • rake db:create RAILS_ENV='development'
    • with mysqladmin
      • mysqladmin -u root create yourapp_development
    • Sanity check with rake db:migrate

Scaffolding

• Dynamic Scaffolding is gone. No more magic.
• Creating scaffolding for a product model
  • ruby script/generate scaffold site title:string description:text url:string
• Update database
  • rake db:migrate
• like rails 1.0 you can revert with
  • rake db:migrate VERSION=0
• to destroy scaffolding run
  • ruby script/destroy scaffold site

Migrations

• generate migration creates a migration. Use add in name for updates and create for new tables
  • ruby script/generate migration add_time_to_site time:datetime
  • rake db:migrate
• At this point your view is out of date. You can hand edit it or you can rerun the generate/scaffold command
