I was wondering if there was a built in function for deleting non-image  
files?

The attachment model gets callbacks for removing thumbnails and the  
actual file:

[http://bs.techno-weenie.net/!source/2923/plugins/attachment\_fu/lib/technoweenie/attachment\_fu.rb#72](http://bs.techno-weenie.net/!source/2923/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb#72)

So, delete the model and it should clean up the file(s) for you.

Sorry, I’m new to rails…  
When you say model, do you mean the database entry?

Guess I don’t; I have this link:  
\<%= link\_to “delete”, { :action =\> “delete” }, :confirm =\> “Are you  
sure?” %\>  
but when I click on it leads me to a blank page  
[http://localhost:3000/files/delete](http://localhost:3000/files/delete)

The action looks like this:  
def delete  
@user.file.destroy  
flash[:notice] = ‘Your file has been deleted.’  
redirect\_to hub\_url  
end

Thanks, took a second look at my routes and found the error

That’s a problem with your routes or your controller, not  
attachment\_fu. Look at your logs and see why it’s a blank screen.
