ruby on rails 3 - Altering nested messages helper from div to unordered list -

-

i using helper method ryan bates railscasts on ancestry display nested messages(code below works perfectly).

def nested_messages(messages)   messages.map |message, sub_messages|     render(message) + content_tag(:div, nested_messages(sub_messages), :class => "nested_messages")   end.join.html_safe end

the above bit of code nests individual divs in tree structure.
i make unordered list, have done this:

def nested_messages(messages)     messages.map |message, sub_messages|         content_tag(:ul, :class => "")             render(message)             content_tag(:li, :class => "nested_messages")                 nested_messages(sub_messages)             end         end     end.join.html_safe end

the generated html looks fine, list items contain no values. doing wrong?

update

i generated html this:

<ul>     <li>main message</li>  <!-- first message -->     <li>         <b>message 1</b>         <ul>             <li>message 1 subchild 1</li>             <li>message 1 subchild 2</li>         </ul>     </li> </ul>

update 2

i have changed , works, dave:

def nested_messages(messages)     messages.map |message, sub_messages|         #render(message) + content_tag(:div, sub_messages, :class => "nested_messages")         content_tag(:ul, :class => "")             content_tag(:li, :class => "nested_messages")                 render(message) + nested_messages(sub_messages)             end         end     end.join.html_safe end

you create ul tag, render message. if that, html like?

things inside ul should in nested li: render message.

you need put in li tag unordered list has valid content.
