I feel a little stupid for having to ask this… But I can't seem find it documented anywhere.

If I've got a Model with FileField, how can I stuff an uploaded FILE into that FileField?

For example, I'd like to do something like this:

class MyModel(Model):
    file = FileField(...)

def handle_post(request, ...):
    mymodel = MyModel.objects.get(...)
    if request.FILES.get("newfile"):
        mymodel.file = request.FILES["newfile"]

But that doesn't appear to work.
