Django Serving a Download File

Have you considered just sending p.body through the response like this:

response = HttpResponse(mimetype='text/plain')response['Content-Disposition'] = 'attachment; filename="%s.txt"' % p.uuidresponse.write(p.body)

python django file download

XSend requires the path to the file in response['X-Sendfile']So, you can do

response['X-Sendfile'] = smart_str(path_to_file)

Here, path_to_file is the full path to the file (not just the name of the file)Checkout this django-snippet

python django file download

There can be several problems with your approach:

file content does not have to be flushed, add f.flush() as mentioned in comment above
NamedTemporaryFile is deleted on closing, what might happen just as you exit your function, so the webserver has no chance to pick it up
temporary file name might be out of paths which web server is configured to send using X-Sendfile

Maybe it would be better to use StreamingHttpResponse instead of creating temporary files and X-Sendfile...
