Model
I find using filecolumn difficult. For one thing, when things go wrong, it tends to just be totally quiet about it, and it's up to you to find out that the file didn't get uploaded after all. Besides, it seems I *have* to use beginformtag / endform_tag to make it work when I need to use named forms (client absolutely won't have standard submit buttons and I have more than one form on the page). Bad, bad.
An updated version of file_column is here:

It features some enhancements and bug-fixes.
This plugin is outdated, there are lots of better options now. Check out file upload fu and others.
Can we show a progress bar while uploading.. i want to do a multi file upload and show the user a progess bar
Needs another development cycle. On my installation, the file column field is blank when editing. It might also be a good idea to store the file path in the database rather than in code, particularly if one needs more than one storage path.
Be sure to download the zip, the svn or script/plugin install may not work. Check out the O'Reilly Rails Cookbook for a useful intro to using file_column
I like the idea, but the documentation is pretty weak. If it could be documented more, I think it would work.
