    <p>I created a sortable list in my RoR project, unfortunately it's not saving the list position. Upon page refresh the items return to their normal spot. I've pasted the code below or you can git it: git://github.com/mdgrech/23notes-.git</p> <pre><code>app/views/notes/index.html.erb ///////////////////////////////////////////////////////////////////////////////////////////// &lt;div id="newNoteDiv"&gt;&lt;/div&gt; &lt;ul id="notesList"&gt; &lt;% for note in @notes %&gt; &lt;li id="&lt;%=h note.position %&gt;"&gt; &lt;span class="handle"&gt;[drag]&lt;/span&gt; &lt;div id="listContent"&gt; &lt;h3&gt;&lt;%= link_to note.title, edit_note_path(note) %&gt;&lt;/h3&gt; &lt;p&gt;&lt;%=h note.content %&gt;&lt;/p&gt; &lt;%= link_to "Destroy", note, :confirm =&gt; 'Are you sure?', :method =&gt; :delete %&gt; &lt;/div&gt; &lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;%= sortable_element("notesList", :url =&gt; sort_notes_path, :handle =&gt; "handle" ) %&gt; app/controllers/notes_controller.rb ////////////////////////////////////////////////////////////////////////////////////////// def index @notes = Note.all(:order =&gt; "position") end def sort params[:notes].each_with_index do |id, index| Note.update_all(['position=?', index+1], ['id=?', id]) end render :nothing =&gt; true end config/routes.rb ////////////////////////////////////////////////////////////////////////////////////////// map.resources :notes, :collection =&gt; { :sort =&gt; :post } map.root :notes app/models/note.rb ////////////////////////////////////////////////////////////////////////////////////////// class Note &lt; ActiveRecord::Base acts_as_list end </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
