I hope I got your question right. I have a little bit different
aproach since django never serves the file directly.
If you are using nginx as a frontend-proxy and static file serving
just configure a protected-download-dir:
location /protected-downloads/ {
alias /var/protected/;
internal;
}
The "internal" is to disallow regular gets so your file is not
downloadable without the "OK" from your view.
Now you can send a X-Accel-Redirect Header from your view to let the
nginx send a file:
@login_required
def download(request, file=None):
response = HttpResponse()
response['Content-Type'] = 'application/octet-stream'
response['X-Accel-Redirect'] = '/protected-downloads/' + file
return response
Of course you can do additional processing in download as storing the
IP and download count to your database.
This soulution has the advantage that your files can be served very
quickly from your proxy instead of a relatively slow mod_python-apache.
If you are using Apache or lighttpd as a frontend-proxy you can use a
similar aproach with: X-Sendfile.
Or you use Amazon s3 etc...
