Instance Method Details

#erb(template) ⇒ Object

Templatize your story output with embedded ruby. This allows the greatest flexibility for presenting the data.

To use, access the ‘@stories` array, and it’s component hashes. Example:

<h1>My Popular Stories</h1>

  <% @stories.each do |story| %>
    <div class="story">
       <h2><a href="<%= story[:url] %>"><%= story[:hed] %></a></h2>
       <% if not story[:img].empty? %>
         <div class="img">
            <a href="<%= story[:url] %>">
             <img src="<%= story[:img] %>">
            </a>
         </div>
       <% end %>
       <% if not story[:blurb].empty? %>
         <div class="blurb"><%= story[:blurb] %></div>
       <% end %>
    </div>
  <% end %>

def erb(template)
  t = File.open(template).read
  template = t.to_s      
  html = ERB.new(template).result(binding)
  
  self.write(html)
end

#html ⇒ Object

HTML is the default output method. It will return a bare-bones page of story output including blurbs and images if available.
