Ruby on Rails reference

As I learn Ruby on Rails I will be adding links to reference materials to this page.

Overall help

• Ruby on Rails API Documentation

Getting started

• "Revisiting Ruby on Rails Revisited" (a series by Curt Hibbs)

Many-to-many / "through" associations (JOINed tables)

• RoR Wiki: has_and_belongs_to_many (simplest to use)
  • RoR Wiki: AccessControlListExample
• has_and_belongs_to_many walkthrough
• RoR Wiki: "Through" Associations (a bit more complicated)
• Learning Rails: Many-to-Many Relationships (fairly complicated)
• Self-referential has_many :through associations (pretty complicated)

DB stuff with Rake

• After you have a migration file XXX_do_whatever.rb in db/migrate, run rake db:migrate to update the database and also db/schema.rb
• If you already have the correct db/schema.rb and you want to load it into your DB, run rake db:schema:load
