Zeus - the database abstraction library
Following James Golick's jamesgolick.com/2010/3/14/crazy-heretical-and-awesome-the-way-i-write-rails-apps.html, I thought I could implement something similar, without too much hassle.
NOTE: no code exists at the moment. These are only ideas.
# Sinatra, but Rails could use the same implementation get "/posts" do @posts = Zeus.posts render :posts_index end get "/post/:id" do @post = Zeus.posts.filter(:id => params[:id]).first render :post end post "/posts" do post = Post.new post.title = params[:post][:title] post.body = params[:post][:body] post.published_at = Time.now.utc Zeus.persist(post) end post "/post/:id/comments" do post = Zeus.posts.filter(:id => params[:id]).first comment = post.add_comment(params[:comment].merge(:ip => request.env["HTTP_REAL_IP"]) # Single DB transaction inserts both rows in the database Zeus.persist(post, comment) end class Post def initialize @comments =  end def add_comment(attributes) comment = Comment.new comment.author_name = attributes[:name] comment.author_email = attributes[:email] comment.body = attributes[:body] comment.author_ip = attributes[:ip] @comments << comment comment end end class Comment end post = Post.new post.title = "Zeus is a new library" Zeus.configure do |config| config.model :post, :table_name => "posts" do string :title text :body integer :comments_count datetime :published_at datetime :created_at, :updated_at, :null => false index :published_at # A single argument for the block receives the Post object defined in the domain model. before_create do |domain_post| domain_post.created_at = Time.now.utc end # Accepting 2 arguments receives both the domain model instance, and the persistence model. before_save do |domain_post, zeus_post| zeus_post.comments_count = domain_post.comments.length domain_post.updated_at = zeus_post.updated_at = Time.now.utc end end # Convention over configuration config.model :comment do integer :post_id, :references => :posts string :author_name, :author_email, :author_ip text :body float :spaminess datetime :approved_at datetime :created_at, :null => false index :post_id, :created_at, :approved_at end end
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
