#generate_html(form_builder, method, options = {}) ⇒ Object

This method demonstrates the use of the :child_index option to render a form partial for, for instance, client side addition of new nested records.

This specific example creates a link which uses javascript to add a new form partial to the DOM.

<%= form_for @project do |project_form| %>
  <div id="tasks">
    <%= project_form.fields_for :tasks do |task_form| %>
      <%= render :partial => 'task', :locals => { :f => task_form } %>
    <% end %>
  </div>
<% end %>

#get_additional_field_value(controller, field) ⇒ Object

You can add additional_fields to the product and variant models. See section 4.2 here: spreecommerce.com/documentation/extensions.html If you do choose to add additional_fields, you can utilize the :use parameter to set the input type for any such fields. For example, :use => ‘check_box’ In the event that you add this functionality, the following method takes care of rendering the proper input type and logic for the supported input-types, which are text_field, check_box, radio_button, and select.
