iirc, you can use http://docs.python.org/lib/module-StringIO.html to
have a file like object from a string, and use that to make your
django File object (
http://www.djangoproject.com/documentation/files/#the-file-object ).
There's probably a better way than this though so you might want to
wait for other replies.
import StringIO
from django.core.files import File
f = StringIO.StringIO()
f.write(data)
myfile = File(f)
Chart.objects.create(xml=default_storage.save('data.xml', myfile))
