The database field does not store the full download path -- only the
filename. response.download() takes the request object and the db object
and knows how to extract the filename from the request, find the associated
table and field in the db, and then find the upload folder (which is an
attribute of the field object) in order to construct the full file path.
response.stream() does not do all that, so you have to provide it with the
full path or an open file(-like) object. Anyway, you can just use
response.download() instead:
def download():
return response.download(request, db, download_filename=request.args(1))
