When a user uploads a file using forms.FileField, you usually want to save it in some way.
To stash the file away on disk, just use the following snippet.
from django.core.files.storage import default_storage
from django.core.files.base import ContentFile
file = request.FILES['your_file_fieldname']
path = default_storage.save('heart_of_the_swarm.txt', ContentFile(file.read()))
There you have it!
