Content_type from a local file?

I’m using a Rake task to add local files into a database designed for
use with attachment_fu.

So, attachment_fu has a “content_type” field, which apparently is
receiving that information from the browser…?

I’m trying to figure out if there is a way to get the content_type of a
file (e.g. ‘image/png’) that you’ve already got in your file-system. I
can’t find anything about this in the Pickaxe, or by looking at the
attachment_fu plugin.

Any help very much appreciated!

contains information about using the mime-types plugin to determine
content_type outside of the CGI library


Terrific. Thanks very much!
