Manually create a Django session

create_django_session.py

from django.contrib import auth
from django.contrib.sessions.backends.db import SessionStore

session = SessionStore(None)
session.clear()
session.cycle_key()
session[auth.SESSION_KEY] = user._meta.pk.value_to_string(user)
session[auth.BACKEND_SESSION_KEY] = 'django.contrib.auth.backends.ModelBackend'
session[auth.HASH_SESSION_KEY] = user.get_session_auth_hash()
session.save()

Worked for me, GJ!
