Rails - Aug 2007 - problem with file_column url generator

Hi,

I have the following in a viewer
Here, @lst = Homework.find(:all)  is an array of homeworks. I checked
this this is correct.
Based on the error below, somehow, the url_for_file_colum does not
like to act on the model element.
I checked the source code to url_for_file_column, and the problem is
with instance_variable_get().
I have no idea wat is going on!  Any help is appreciated.   Gordon.

----------------
<% @lst.each do |hwk| %>
  <p>
    <%= link_to File.basename(hwk.file_name), url_for_file_column(hwk,
"file_name") %>
  </p>
<% end %>
---------------------

The File.basename(xxx) prints properly. However, I get the following
message for url_for_file_column:

------------------------------
4: <%# for hwk in @list %>
5: <% @lst.each do |hwk| %>
6:   <p>
7: 	<%= link_to File.basename(hwk.file_name), url_for_file_column(hwk,
"file_name") %>
8:   </p>
9: <% end %>
10: </div class="list">

Active Record form helper always require an instance variable name
for their first arguments.  So write:

<% @lst.each do |@hwk| %>
   <p>
     <%= link_to File.basename(@hwk.file_name), url_for_file_column(:hwk,
"file_name") %>
   </p>
<% end %>
