i have acts_as_tree installed as plugin under rails 2.0.2 and also its
defined in class TreeItems, but when i put this in my view
- Furniture
<% TreeItem.root.category.children do |cat_children| %>
- <%=h cat_children.name %> <% end %>
it gives me this:
undefined method `acts_as_tree’ for #Class:0x2bb3f30
