Newbi - form_remote_tag doesn't produce any HTML

Hi,

I'm completely new to Ruby/Rails, so sorry for asking newbi questions.

I'm just following the Agile Web Development book, and got to the AJAX
section.
Added the code from the web, to generate the .js which triggers the
AJAX, but no .js code appears in the HTML.

This is what I've added to the .rhtml code (from the book):

···

__________________
<% for product in @products -%>
  <div class="entry">
    <img src="<%= product.image_url %>"/>
    <h3><%= h(product.title) %></h3>
    <%= product.description %>
    <span class="price"><%= number_to_currency(product.price) %></span>

    <% form_remote_tag :url => { :action => :add_to_cart, :id =>
product } do %>
      <%= submit_tag "Add to Cart" %>
    <% end %>
      <br clear="all"/>
  </div>
<% end %>

Surprisingly, the HTML source that I see in the browser doesn’t contain
any .js code. This is what I’m getting:
__________________
  <div class=“entry”>
    <img
src=“http://www.onthegosoft.com/images/printer/passport_photo_small.png”/>
    <h3>Passport Photo</h3>
    Our great program for making passport picture!
    <span class=“price”>$9.95</span>

      <br clear=“all”/>
  </div>
  <div class=“entry”>
    <img
src=“http://www.onthegosoft.com/images/photobackup/photo_backup_small.png”/>
    <h3>Photo Backup</h3>
    <p><b>Great program</b> for backing up <b>digital photos</b>.</p>

    <span class="price">$29.95</span>

      <br clear="all"/>
  </div>

Notice, just before the <br> tag at the end, a .js snippet should
appear, triggering the AJAX.
Any advice how I can debug this?

Thanks,

You might get better luck asking the Rails list...

That said... see below.

   <% form_remote_tag :url => { :action => :add_to_cart, :id =>
product } do %>
     <%= submit_tag "Add to Cart" %>
   <% end %>

I think form_remote_tag/do is edge rails... are you using edge? if you're not, change that, and don't forget to change "<% form..." to "<%= form...", so they actually output something.

</div>
<% end %>
