First, set up your rails project:

rails yoursite.com

Navigate into your project:

cd yoursite.com

Set up the database file:

vi config/database.yml


It should look something like this:

development:
  adapter: mysql
  database: test
  timeout: 5000

test:
  adapter: mysql
  database: test
  timeout: 5000

production:
  adapter: mysql
  database: test
  timeout: 5000

Generate a model:

script/generate model book

edit the file containing the table structure for the model:

vi db/migrate/001_create_books.rb

Change the file to this:


class CreateBooks < ActiveRecord::Migration
        def self.up
                create_table :books do |t|
                        t.column :title, :string
                        t.column :author, :string
                        t.column :isbn, :string
                        t.column :subject, :string
                        t.timestamps
                end
        end

        def self.down
                drop_table :books
        end
end

Initiate the migration:

rake db:migrate

Then edit the model itself:

vi apps/models/book.rb


class Book < ActiveRecord::Base
        validates_presence_of :title
        validates_presence_of :author
end

Now create the controller and then scaffold:

script/generate controller book
script/generate scaffold book book
