Well maybe 15 lines is a bit of an exaggeration, but it’s close. Most
of this comes from others’ work, but I was able to tool it to my needs.
All of these lines go in the model, which for me has a :file and
:content_type attributes. :file stores the complete path to the
uploaded file. Be sure to change the string in path_to_file to the
place where you want files stored. Also, sanitize_filename doesn’t HAVE
to be private.
Enjoy!

homebrewed file upload because I had issues with file_column. I
probably wrote about 15 lines of code, most of them in the model. I’m
willing to share, if anyone wants the code.
