Question

In my controller I’m trying to do something like:

  uploader = object[params[:attribute]]
  uploader.retrieve_from_store!(params[:file])
  uploader.cache_stored_file!
  send_file uploader.file.path

But the problem is that object[params[:attribute]] is returning a String(the DB record with the filename), not my carrierwave object (I already checked that object.attribute is returning the uploader, it works). How can I get the uploader or maybe how can I initialize it?

Thanks in advance

If somebody crosses with the same problem, I did it with:

uploader = object.send(params[:attribute])
