Question

The Python ZipFile API seems to allow the passing of a file path to ZipFile.write or a byte string to ZipFile.writestr but nothing in between. I would like to be able to pass a file like object, in this case a django.core.files.storage.DefaultStorage but any file-like object in principle. At the moment I think I’m going to have to either save the file to disk, or read it into memory. Neither of these is perfect.

Answer 1

You are correct, those are the only two choices. If your DefaultStorage object is large, you may want to go with saving it to disk first; otherwise, I would use:

zipped = ZipFile(...)
zipped.writestr('archive_name', default_storage_object.read())

If default_storage_object is a StringIO object, it can use default_storage_object.getvalue().
