Ruby on Rails

Let me first confess that I have only few hours of experience with ruby. And even less with Rails. But I could somehow manage to try out and put some code here. Rails like ASP.NET is a web development framework. Its becoming very popular these days. There are ways in which AJAX can be done with lesser pain in Rails. Code for simplest AJAX functionality is shown below, it resides in the *.rhtml files :

 <div id="hello_div">
      
      <%= link_to_remote( "Click  here",
                         :update => "hello_div",
                         :url =>{ :action => :say_hello }) %>
      for welcome message.
 </div>

• Creates a hyperlink.
• Executes the server side 'say_hello' function and gets the output.
• Refreshes the contents of 'hello_div' with output.

class TestController< ApplicationController
   scaffold :test
  
  def index
  end

  def say_hello
    render_text "<p>Hello Geek !</p>"
  end
end
