partial _form not rendering

I am working through the agile web development with rails and after generating the pages from the "product" scaffold, the partial within the new.rhtml file no longer renders to the browser.

Is there something that I am missing here?

Thanks for any help.

<!-- new.rhtml --> <h1>New product</h1>

<% form_tag :action => 'create' do %>   <%= render :partial => 'form' %>   <%= submit_tag "Create" %> <% end %>

<%= link_to 'Back', :action => 'list' %>

<!-- _form.rhtml --> <%= error_messages_for 'product' %>

<!--[form:product]--> <p><label for="product_title">Title</label><br/> <%= text_field 'product', 'title' %></p>

<p><label for="product_description">Description</label><br/> <%= text_area 'product', 'description' %></p>

<p><label for="product_image_url">Image url</label><br/> <%= text_field 'product', 'image_url' %></p>

<p><label for="product_price">Price</label><br/> <%= text_field 'product', 'price' %></p> <!--[eoform:product]-->
