Hmm, I''m using file_column and going by this tutorial, the files upload ok and I can see the fields updated in the database, but I am getting this error: "Trying to access file_column, but primary key got lost." Thanks in advance -- Posted via http://www.ruby-forum.com/.
Sorry, this is what it I am getting back from this code:
view:
<% @images.each do |@image| %>
<p>Title: <%=h @image.name %></p>
<%= image_tag
url_for_file_column(''image'',''file'') %>
<% end %>
controller:
def list_images
@images = Image.find(:all)
end

I don''t have code in front of me, but I think the problem is in your url_for_file_column I think it should be: url_for_file_column(@image,''file'') instead. Right now you are just passing url_for_file_column a string with contents ''image'', not the @image object (with the attendant id). Nicholas P.
