Rails - Jan 2010 - Iterating through an Instance Variable in my View

I have an instance variable called @ls which is an array that contains a
list of files in a directory.

When I call this instance variable in my view like this:

   <%= @ls %>

It shows the entire list of files in the array.

Since I need to edit what is displayed for each file name in the array,
I want to iterate through it in my view.

When I put this code in my view:
   <% @ls.each do |a| %>
   a.puts
   <% end %>

... it only prints out the letter "a" as many times as the size of the
array.

Can anyone help me out with correcting this issue?

thanks

Because there''s an implicit to_s on the contents of <%= %>

You probably want them in some sort of list, right?

<ul>
   <% @ls.each do |a| %>
     <li>
       <%= a %>
     </li>
   <% end %>
</ul>

Replace the ul/li markup with whatever makes sense for your results.
