In background, I want it to reload and shows the number how many unread messages are there. I want that without refreshing page. I mean using ajax. If I had this in menu, how can I refresh only this section every 30 secs? <pre><code><li><%= link_to sanitize(' ') + "received messages" + sanitize(' '+current_user.mailbox.inbox(:read => false).count(:id, :distinct => true).to_s+''), messages_received_path %></li> </code></pre> messages_controller.rb <pre><code> def received if params[:search] @messages = current_user.mailbox.inbox.search_messages(@search).page(params[:page]).per(10) else @messages = current_user.mailbox.inbox.page(params[:page]).per(10) end add_crumb 'Messages Received', messages_received_path @box = 'inbox' render :index end </code></pre> UPDATE:_______________________________ assets/javascript/refresh_messages_count.js <pre><code>$(document).ready(function () { // will call refreshPartial every 3 seconds setInterval(refreshPartial, 3000) }); function refreshPartial() { $.ajax({ url: "messages/refresh_part"; }) } </code></pre> messages_controller.rb <pre><code>def refresh_part @message_count = current_user.mailbox.inbox(:read => false).count(:id, :distinct => true) # get whatever data you need to a variable named @data respond_to do |format| format.js {render :action=>"refresh_part.js"} end end </code></pre> views/layouts/_menu.html.erb <pre><code><%= render :partial => "layouts/message_received_count" %> </code></pre> views/layouts/_message_received_count.html.erb <pre><code><% if user_signed_in? && current_user.mailbox.inbox(:read => false).count(:id, :distinct => true) > 0 %> <li><%= link_to sanitize(' ') + "Received" + sanitize(' '+@message_count.to_s+''), messages_received_path %></li> <% else %> <li><%= link_to sanitize(' ') + "Received", messages_received_path %></li> <% end %> </code></pre> views/messages/refresh_part.js.erb <pre><code>$('#message_received_count').html("#{escape_javascript(render 'layouts/messages_received_count', data: @message_count)}"); </code></pre>

Guidance

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.
