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,
