Forum: Ruby on Rails acts_as_tree question

Hi,

I'm trying to implement a very simple acts_as_tree search in my index
html.

I am able to show the parents, with no issue, but the children will
not show.

I have something like this for the parent, which displays fine:

<% for group in Group.roots %>
<td>
  <tr>
  <a href="#" onclick="Effect.BlindDown('show_<%= group.id%>');return
false;">+</a>
     <!-- calls the show method, but utilizes the acts_as_tree -->
     <%= link_to (group.name), group  %>  <br>
     <div id ="show_<%= group.id%>" style="display:none;">

For the children, however, using the following will not work because
it is looking to the index method.

<% for group in Group.children %>
<%= link_to (group.name), groups %>

Any pointers?  Should I be using object.children to get the children?
thanks

Hi,

I think you've made a little mistake...

The correct form is this:

<% for group in Group.roots %>
  ...
  <%= link_to (group.name), group  %>
  ...
  <% for child in group.children %>
    ...
    <%= link_to (child.name), child %>
    ...

Notice the use of "group.children" instead "Group.children"

Hope this helps...

You probably don't want acts_as_tree in any case.  Awesome_nested_set is 
much more efficient.

Best,
