Ruby on Rails - Awesome nested set plugin

Question

Hi, Is there a simple way to display the entire nested set when using this plugin? What I would like to do is display an unordered list of root nodes with another unordered list inside each child that also contains children and so on?

Any advice appreciated.

Thanks.

There are a few ways to do this. The simplest is to just start with the roots and parse each node and it's children. The first thing I'd do is make a partial for a the node markup:

_your_model.html.erb

<li>
  <%= your_model.name %>

  <% unless your_model.children.empty? %>
    <ul>
      <%= render your_model.children %>
    </ul>
  <% end %>
</li>

Next edit your view so that the first root nodes are rendered:

<ul>
  <% YourModel.roots.each do |node| %>
    <%= render node %>
  <% end %>
</ul>
