Acts_as_tree question

db_333 · February 9, 2010, 6:48am

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 %>

+ <%= link_to (group.name), group %>

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.
