Rails - Nov 2007 - newbie: need to delete object in loop

Hi, sorry for this rather simplistic question, but I can''t think of a
good way of googling the answer (just been trying for 20 mins).
Anyway... so I have this rather simplistic piece of code:

<% for artwork in @artworks %>

  <% if artwork.medium_id %>
    <% medium = Medium.find(artwork.medium_id) %>
  <% end %>

  <% if medium %>
    <p><%= medium.name %></p>
  <% end %>

<% end %>

There are 6 artworks, but only the first one has a medium_id, the others
are not set. When the code runs the medium is picked up in the first
iteration of the loop, and then printed each subsequent iteration.

I naively assumed that "medium" would be destroyed at the end of each
loop, but it seems I was wrong. Is there any way for me to force its
destruction?

cheers,

ali
