I’m trying to set up an upload interface to use mod\_porter, however I  
can’t seem to read the hash that it hands off to the rails method.

It seems like I should be able to access the hash content using params  
[:file][:data][:filename] and params[:file][:data][:path] etc…

But it throws an error saying:

undefined method `[]’ for #\<ModPorter::UploadedFile: … \>

What am I doing wrong?

Nobody?

Ok maybe I’m asking the wrong question:

Has Rack come up with a way to handle uploads in a way that scales  
well without emptying the rails thread pool so that nobody is even  
using mod\_porter?
