Hi,

Your best option is to add a foreign key to your user model (usually
django.contrib.auth.models.User) in your model that handles your datafiles.

from django.contrib.auth.models import User

class Datafile(models.Model):
     user = models.ForeignKey(User)
     ...


When a user upload a datafile, don't forget to set the user field:

mydatafile.user = request.user


And then you can filter datafiles:

Datafile.objects.filter(user=request.user)
