Defined in:

Overview

View Generator

The view generator allows you to define content using an ERB template - similar to Ruby on Rails.

Example use within a Controller:

require 'cuca/generator/view'
class IndexController
  include Cuca::Generator::View

  def run
    @some_variable = "Stuff"
    @page_title = "Hello World"
    view('template.rhtml')
  end
end

And the template (template.rhtml)

<html>
 <head>
  <title><%= @page_title %></title>
 </head>
 <body>
   <% (1..10).each do |idx|  %>  <!-- Embedded Ruby Code ->
     <%= idx.to_s %> - <b>Some variable: <%= @stuff %></b><br/>
   <% end %>
   An external Widget: <%= Link('/to/somewhere') { b { "Click me" }} %>
 </body>
</html>
