This code is also very suitable for downloading large files and basically does not consume memory. Only a portion of the data is read to the memory each time, and then provides the download function.

Def Download (request): def readFile (fn, buf_size = 262144): f = open (fn, "rb") while True: c = f. read (buf_size) if c: yield c else: break f. close () filename = '/usr/local/1.jpg' try: response = HttpResponse (readFile (file), mimetype = 'application/octet-stream ') response ['content-disposition'] = 'attachment; filename = % s' % 'attachment 'response T: response = HttpResponse ('') return response
