Hi, url_for_file_column @variable, 'name', takes an instance variable. My question is, what if I don't want to have to retrieve the instance variable every single time but I have the image id, along with its name with me. Could I contruct that object in a view and pass it to url_for_file_column: <% @picture = Picture.new %> @picture.id = ... @picture.name = ... %> and then pass @picture in? I tried this but when I tried the name assignment, I got the following: Do not know how to handle a string with value 'somename.jpg' that was passed to a file_column. Thanks.

I'm pretty sure (away from devbox at the moment) that a file_column field actually wants to be passed a FileIO (or StringIO, I think) object so that it can handle the actual data. In this case, you may well be better off either creating a mock class that supports the methods that url_for_file_column requires (which I *think* will be limited to name, id and class), or writing your own helper to use instead of url_for_file_column.
