 class Member(models.Model):
        username = models.CharField(max_length=50, unique=True)
        password = models.CharField(max_length=50)
        document = models.ForeignKey("Document")

   # Handle file upload
    if request.method == 'POST':

        if form.is_valid():
            newdoc = Document(docfile = request.FILES['docfile'])

Answer 1

You may use django-registration-redux for authentication, after that you should use this code sample to indicate your foreign key:

from django.contrib.auth.models import User

class Document(models.Model):
    user = models.ForeignKey(User, null=True, blank=True)
    ...
