Let me present another more elegant example of Nitro:

require 'nitro_and_og'

class Content
  attr_accessor :title, :body, String
  attr_accessor :hits, Fixnum

  def initialize(title)
    @title = title
  end
end

class Category < Content
  attr_accessor :wow, String
  has_many :posts
end

class Post < Content
  belongs_to :category
end

class Demo
  def categories(oid)
    category = Category[oid]
    print "<ul>"
    for post in category.posts
      print "<li>{post}</li>"
    end
    print "</ul>
  end

  def init_db
    c1 = Category.create('Hello')
    c2 = Categroy.create('World')
    post = Post.new('Hello world')
    post.category = c1
    post.save
  end
end

Og.start
Nitro.start Demo

hit http://localhost:9999/init_db to put dummy data in the database
(sqlite used by default)
hit http://localhost:9999/categories/1 to view the posts in category 1.

Notice how nitro automatically handles nice urls. Also note that you
could (and should) use a separate xhtml template (view) to handle the
page rendering instead of using print statements (or the programmatic
builder).

But you really have to experiment with Nitro, there are so many
features/options.


regards,
George.
