We constructed a toy application that showed us the following:

• How to create a new Rails application and how to create a new controller in that application
• How to make dynamic content in that controller and display it via the view template
• How to link pages together

<pre name="code" class="ruby"><h1>hello</h1><h1>It is now <%= @time %> </h1><p><%= link_to "Goodbye", say_goodbye_path %>!</p><p>Addition:<%= 1+2 %></p><p>Conctenation:<%= "cow" + "boy" %></p><p>Time in one hour:<%= 1.hour.from_now.localtime %></p>
