look up file\_column:

[http://www.kanthak.net/opensource/file\_column/](http://www.kanthak.net/opensource/file_column/)

i think there are other things out there (in fact, maybe even better)  
but i think this quite basic and good enough.

You can also put this kind of stuff in your controller (for example) or  
for DRY put it in your model…

```
@file = params[:image][:img]
if @file.original_filename.length > 0
  filename = session[:dirname] + "/" + @file.original_filename
  File.open(filename, "w") { |f| f.write(@file.read) }
end
redirect_to :action => "index"

```

DRY means Don’t Repeat Yourself, a common mantra for rails developers.  
For instance, using one of the above mentioned plugins means this  
will probably be taken care of for you.

If you’re on rails 1.2 and were looking at acts\_as\_attachment, I’d  
suggest my refactored update attachment\_fu. It has an #uploaded\_data  
accessor that handles the above code in your model.
