Here is a small example btw:

class Comment; end

class Article
has_many Comment, :comments
prop_accessor String, :title
prop_accessor String, :body
prop_accessor Hash, :options

def initialize(title = nil, body = nil)
@title = title
@body = body
@options = {"hello" => "world"}
end
end

class Comment
belongs_to Article, :article
prop_accessor String, :body
prop_accessor Time, :create_time

def initialize(body = nil)
@create_time = Time.now
@body = body
end
end

$og.manage_classes(Article, Comment)

article = Article.new("title", "the body")
article.save!

# lookup
article = Article[1]
article = $og.load(1, Article)

comment = Comment.new("the comment")
comment.article = article
comment.save!
# or
# $og << comment
# or
# Comment.save(comment)

p article.comments

The backend database and the schema for those objects
is created automatically.


have fun,
