Question

I am avoiding the creation of files on disk, this is what I have got so far:

def get_zip(request):
    import zipfile, StringIO
    i = open('picture.jpg', 'rb').read()
    o = StringIO.StringIO()
    zf = zipfile.ZipFile(o, mode='w')
    zf.writestr('picture.jpg', i)
    zf.close()
    o.seek(0)
    response = HttpResponse(o.read())
    o.close()
    response['Content-Type'] = 'application/octet-stream'
    response['Content-Disposition'] = "attachment; filename=\"picture.zip\""
    return response

Do you think is correct-elegant-pythonic enough? Any better way to do it?

Thanks!

Answer 1

For StringIO you should generally use o.getvalue() to get the result. Also, if you want to add a normal file to the zip file, you can use zf.write('picture.jpg'). You don’t need to manually read it.
