    <p>Alright. I am working with RoR and jQuery and I have already got my update and create links working and functioning with their .js.erb files. The problem arises when in create with this line of code.</p> <pre><code>#create.js.erb $("#promo_types").append("&lt;%= escape_javascript(render(:partial =&gt; "promotion_type"))%&gt;"); </code></pre> <p>it is throwing an error: <em>You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each</em></p> <pre><code>#index.erb &lt;div id="promo_types"&gt; &lt;%= render :partial =&gt; "promotion_type" %&gt; &lt;/div&gt; #_promotion_type &lt;% @promotion_types.each do |@promotion_type| %&gt; &lt;table&gt; &lt;tr&gt; &lt;td width="200"&gt;&lt;%=h @promotion_type.name %&gt;&lt;/td&gt; &lt;td width="20"&gt;&lt;a class="Edit&lt;%=h @promotion_type.id %&gt;" href="#"&gt;&lt;img src="/images/pencil.png" alt="Edit" title="Edit" /&gt;&lt;/a&gt;&lt;/td&gt; &lt;td width="20"&gt;&lt;%= link_to(image_tag('/images/bin.png', :alt =&gt; 'Remove', :title =&gt; "Remove"), @promotion_type, :class =&gt; "deleteCategory") %&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;div id="popupEdit&lt;%=h @promotion_type.id %&gt;" class="popupEdit"&gt; &lt;a class="popupClose&lt;%=h @promotion_type.id %&gt;" id="popupClose"&gt;x&lt;/a&gt; &lt;%= render :file =&gt; 'promotion_types/edit' %&gt;&lt;/div&gt; &lt;% end %&gt; </code></pre> <p>It doesn't like that first line of code of the partial when I try to append the row using ajax.</p> <p>My only other question is concerning my update.js.erb. I works fine. If i click edit and update it updates the changes, but I don't see them till I refresh the page. I don't want to .append the partial because the would add the edit to the bottom of the list. Do I use a .html to refresh my partial thru AJAX?</p> <p>EDIT:</p> <pre><code>#full create.js.erb $("#promo_types").append(&lt;% escape_javascript(render(:partial =&gt; "promotion_type"))%&gt;"); $("new_promotion_type")[0].reset(); $(".addtoggle01").toggle(); $(".addtoggle01").before('&lt;div id="notice"&gt;Your promotion type has been successfully submitted.&lt;/div&gt;'); </code></pre> <p>It resets my form, hides the form, and displays the notice, but it isn't appending anything and not throwing any errors either.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
