The question is this, how do i display the acts\_as\_tree tree i have  
created? I have this:

\<% puts TreeItem.root.children.find(:all)%\>

also i tried: (using the display\_children method from the agile book.

\<% display\_children(root).each do |child| %\>

- \<%= child.name %\>

  
\<% end %\>

the method:

def display\_children(parent)  
puts parent.children.map { |child| child.name }.join(", ")  
end

what am i doing wrong?

What have these options generated for you? It’s hard to know what’s  
wrong unless you tell us what you’re getting (or not getting).
