Rails form_tag not showing

Question

I follow this simple tutorial http://railscasts.com/episodes/37-simple-search-form which seems great, but my form tag doesn't work. Here is my html code! The form tag is not even displayed.

<h1>Listing applications</h1> <% form_tag applications_path do %> <p> <%= text_field_tag :search %> <%= submit_tag "Search" %> </p> <% end %> <table> <tr> <th>Name</th> <th>Enviroment</th> <th>Applicationurl</th> <th>Server</th> <th>Additional Servers</th> <th></th> <th></th> <th></th> </tr> <% @applications.each do |application| %> <tr> <td><%= application.name %></td> <td><%= application.date %></td> <td><%= application.size %></td> <td><%= application.author %></td> <td><%= application.addi_servers %></td> <td><%= link_to 'Show', application %></td> <td><%= link_to 'Edit', edit_application_path(application) %></td> <td><%= link_to 'Destroy', application, confirm: 'Are you sure?', method: :delete %></td> </tr> <% end %> </table> <br /> <%= link_to 'New Application', new_application_path %> 

And I have only one model, the "Application"

According to guide you need = up to form_tag

 <%= form_tag("/search", :method => "get") do %> <%= label_tag(:q, "Search for:") %> <%= text_field_tag(:q) %> <%= submit_tag("Search") %> <% end %>
