    <p>I've been implementing some nice interactive interfaces that can sort lists in my m rails app for models that use <code>acts_as_list</code>. I have a sort function that gets called and sets the position for each record afterr each drag and drop using the sortable_element script.aculo.us function.</p> <p>This is an example of the controller action that handles the sort after the drag and drop completes:</p> <pre><code> def sort params[:documents].each_with_index do |id, index| Document.update_all(['position=?', index+1], ['id=?', id]) end end </code></pre> <p>Now I am trying to do this same thing with a model that is a nested set (<code>acts_as_nested_set</code>). An example of the type of interface interaction: <a href="http://script.aculo.us/playground/test/functional/sortable_tree_test.html" rel="nofollow noreferrer">http://script.aculo.us/playground/test/functional/sortable_tree_test.html</a></p> <p>I am stuck on how to write the controller action to handle the sort when the drag and drop completes.</p> <p>I've added the :tree=>true parameter to the sortable _element function so far which appears to send a list of hashes but it seems that I am still missing information about the entire nested order....</p> <p>I was certain this has been done before and didn't want to try to reinvent the wheel, but I can't seem to find any examples of the controller action &lt;-> view with js function setup to handle a sortable <code>acts_as_nested_set</code></p> <p>Any help with creating an interactive sortable nested set in rubyonrails would be appreciated!</p> <p>Thanks,</p> <p>John</p>

    3. COAre there built-in ways to match the order passed from params hash to the entire nested set of all of the items in the model?

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).
