python - Removing tmp file after return HttpResponse in django

I'm using the following django/python code to stream a file to the browser:

wrapper = FileWrapper(file(path))
response = HttpResponse(wrapper, content_type='text/plain')
response['Content-Length'] = os.path.getsize(path)
return response

Is there a way to delete the file after the reponse is returned? Using a callback function or something? I could just make a cron to delete all tmp files, but it would be neater if I could stream files and delete them as well from the same request.

See Question&Answers more detail:os

You can use a NamedTemporaryFile:

from django.core.files.temp import NamedTemporaryFile
def send_file(request):
    newfile = NamedTemporaryFile(suffix='.txt')
    # save your data to newfile.name
    wrapper = FileWrapper(newfile)
    response = HttpResponse(wrapper, content_type=mime_type)
    response['Content-Disposition'] = 'attachment; filename=%s' % os.path.basename(modelfile.name)
    response['Content-Length'] = os.path.getsize(modelfile.name)
    return response

temporary file should be deleted once the newfile object is evicted.
