partials and instance variables for file_column
Hi,
Sebastian Kanthak of the file_column-Plugin wrote once:
"is the photo object inside a local variable or an instance variable
(e.g. photo or @photo)? url_for_file_column only works with instance
variables, like all other active record form helpers. Could this be
the problem?"
So I''m using file_column in a partial, e.g.

problems with file_column plugin
1) installation is not as smooth as some other plug-ins. If you follow
the instructions on
http://www.kanthak.net/opensource/file_column/
it makes a directory called trunk instead of file_column. You have to
manually rename it to file_column. I guess this is a minor annoyance but
it gives me the feeling that things aren''t quite like other plugins.
2) I get this error: undefined

Resize uploaded image file without creating temp file?
Hi,
I need to take a single uploaded image file and save three resized
versions of it, a thumbnail, normal and large version. I was planning on
doing this in my model by having an array of geometry strings and looping
through them, each time saving a new image object resized to the correct
geometry. I know that file column does similar stuff, but I would prefer
to have a separate database row
