Hi!

This is what I want…

blog | photos | about

This is what my code gives me…

blog | photos | about |

The last “|” is to much…

```auto
  <% for page in @menu_pages %>
    <li><%=page%></li>
    <li>|</li>
  <% end %>
```

Is there any way I can get some sort of indication whether the array  
@menu\_pages has a next element?

I use this:

```
    <%= render(:partial => 'navbar_item',
               :collection => @navbar_items,
               :spacer_template => 'navbar_spacer') %>

```

With obviously navbar\_item displaying an item and the navbar\_spacer the  
spacer.

\<%= @menu\_pages.map { |page|  
content\_tag(:li, page.to\_s)  
}.join(content\_tag(:li, ‘|’)) %\>

Which should probably be extracted to a helper so you can call:

\<%= menu\_items\_for(@menu\_pages, ‘|’) %\>

And there will probably be someone who says “you should use do-end  
for a multi-line block”, but I’m believing (and trying to follow) Jim  
Weirich’s style of using {} when the value of the block is used and  
do-end otherwise (or when precedence dictates).
