1. Just installed Ruby and Rails on my MacOSX Leopard. The current version of rails is 1.2.6. I wanted to upgrade using gem update –system but it seems like taking forever.. So I did a manual install of ruby, rubygems then rails..

2. The tutorial that I followed was from http://hivelogic.com/articles/2008/02/ruby-rails-leopard

3. Browsed the first few pages of the hilarious http://www.poignantguide.net/ruby

4. Went for a book. Found Simply Rails 2.0 on Boox24x7 and Safari. Added that to my shelf and read chapters 1 – 5 on my first night.

5. Was able to setup database configuration in config/database.yml using Postgres. I have yet to study how oracle works.

6. rake db:migrate is a convenient way of building your database schema without using SQL. Simply Rails 2.0:Chapter 5:Generating a Model introduced inserting records using script/console

7. URL Helpers for Story Resource
stories_path /stories
new_story_path /stories/new
story_path(@story) /stories/1
edit_story_path(@story) /stories/1/edit

Remember to define the route in config/routes.rb
map.resources :users, :categories

8. Naming Conventions

Variables – lowercase letters and words separated by underscores.
i.e name, country_of_origin

DB Table and Column names should follow convention is always pluralised.
i.e users

Classes and Modules – no underscores and each word is capitalized
i.e User, UserCategories
