    copied!<p>I've recently built a fairly deep nested form using http:// github.com/timriley/complex-form-examples for guidance. The form partial uses the following in order to render new fields when a link is clicked:</p> <pre><code>&lt;%= yield :warehouses_fields_template %&gt; &lt;%= yield :ratgrades_fields_template %&gt; </code></pre> <p>The content for these is generated in the ApplicationHelper as such:</p> <pre><code>def new_child_fields_template(form_builder, association, options = {}) content_for "#{association}_fields_template" do options[:object] ||= form_builder.object.class.reflect_on_association(association).klass.new options[:partial] ||= association.to_s.singularize options[:form_builder_local] ||= :f content_tag(:div, :id =&gt; "#{association}_fields_template", :style =&gt; "display: none") do form_builder.fields_for(association, options[:object], :child_index =&gt; "new_#{association}") do |f| render(:partial =&gt; options[:partial], :locals =&gt; {options[:form_builder_local] =&gt; f}) end end end unless content_given?("#{association}_fields_template") end def content_given?(name) content = instance_variable_get("@content_for_#{name}") ! content.nil? end </code></pre> <p>Everything seemed to be working perfectly on rails 2.3.8, but after upgrading to Rails 3 rc today the templates are no longer loaded. Has something changed that would make the above code invalid? Anyone else noticing the same problem?</p> <p>Any help would be greatly appreciated, Thanks!</p> <p>For reference, this is the relevant jQuery code as well:</p> <pre><code>$(function() { $('form a.add_child').live('click', function() { // Setup var assoc = $(this).attr('data-association'); // Name of child var content = $('#' + assoc + '_fields_template').html(); // Fields template // Make the context correct by replacing new_&lt;parents&gt; with the generated ID // of each of the parent objects var context = ($(this).parents('.fields').children('input:first').attr('name') || '').replace(new RegExp('\[[a-z]+\]$'), ''); // context will be something like this for a brand new form: // project[tasks_attributes][1255929127459][assignments_attributes][1255929128105] // or for an edit form: // project[tasks_attributes][0][assignments_attributes][1] if(context) { var parent_names = context.match(/[a-z]+_attributes/g) || [] var parent_ids = context.match(/[0-9]+/g) for(i = 0; i &lt; parent_names.length; i++) { if(parent_ids[i]) { content = content.replace( new RegExp('(\\[' + parent_names[i] + '\\])\\[.+?\\]', 'g'), '$1[' + parent_ids[i] + ']' ) } } } // Make a unique ID for the new child var regexp = new RegExp('new_' + assoc, 'g'); var new_id = new Date().getTime(); content = content.replace(regexp, new_id) $(this).parent().before(content); return false; }); }); </code></pre> <p>I've included a Gist with some more of the relevant pages if it'll help: <a href="http://gist.github.com/536704" rel="nofollow noreferrer">http://gist.github.com/536704</a></p>
