Having Django serve downloadable files

by

For the “best of both worlds” you could combine S.Lott’s solution with the xsendfile module: django generates the path to the file (or the file itself), but the actual file serving is handled by Apache/Lighttpd. Once you’ve set up mod_xsendfile, integrating with your view takes a few lines of code:

from django.utils.encoding import smart_str

response = HttpResponse(mimetype="application/force-download") # mimetype is replaced by content_type for django 1.7
response['Content-Disposition'] = 'attachment; filename=%s' % smart_str(file_name)
response['X-Sendfile'] = smart_str(path_to_file)
# It's usually a good idea to set the 'Content-Length' header too.
# You can also set any other required headers: Cache-Control, etc.
return response

Of course, this will only work if you have control over your server, or your hosting company has mod_xsendfile already set up.

EDIT:

mimetype is replaced by content_type for django 1.7

response = HttpResponse(content_type="application/force-download")

EDIT:
For nginx check this, it uses X-Accel-Redirect instead of apache X-Sendfile header.
