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 %\>

\<%= medium.name %\>

  
\<% 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
