Django session middleware

Add hosted login and an encrypted session cookie to Django with ScalekitAuthMiddleware

Use scalekit.frameworks.django to add hosted login, an encrypted sk_session cookie, token refresh, and logout.

Typical flow: install the django extra, add settings and ScalekitAuthMiddleware, include the auth URLs, and decorate one view with @login_required. There is no ScalekitAuth instance to construct.

Requires scalekit-sdk-python 2.17.0 or later.

Register these URLs in the Scalekit Dashboard under Authentication > Redirects before you test. Paths have no trailing slash.

Dashboard field	Must match
Redirect URI	`SCALEKIT_REDIRECT_URI` exactly, for example `http://localhost:8000/callback`
Post Logout Redirect URI	Absolute URL after full logout, for example `http://localhost:8000/`
Initiate Login URL	Login path, for example `http://localhost:8000/login`

Store credentials in environment variables. Never hard-code secrets.

SCALEKIT_ENVIRONMENT_URL=https://your-env.scalekit.com
SCALEKIT_CLIENT_ID=skc_...
SCALEKIT_CLIENT_SECRET=...
COOKIE_ENCRYPTION_SECRET=   # openssl rand -base64 32
REDIRECT_URI=http://localhost:8000/callback

Keep COOKIE_ENCRYPTION_SECRET identical on every server instance.

Install the package

pip install "scalekit-sdk-python[django]"

from django.urls import include, path
from . import views

urlpatterns = [
    path("", include("scalekit.frameworks.django")),
    path("account", views.account),
]

from django.http import JsonResponse
from scalekit.frameworks.django import login_required

@login_required
def account(request):
    return JsonResponse({"sub": request.scalekit_user["sub"]})

Open http://localhost:8000/account. A missing session returns 302 to /login, not a JSON 401.

request.scalekit_user is access-token claims, or None when the visitor is anonymous. sub is always present on an authenticated user. email appears only when you add it as a custom access-token claim.

ScalekitAuthMiddleware

classScalekitAuthMiddlewarehttps://github.com/scalekit-inc/scalekit-sdk-python/blob/main/scalekit/frameworks/django.py

#__call__

Django middleware that reads sk_session on every request. Sets request.scalekit_user (None if unauthenticated) and writes a refreshed cookie about 10 seconds before expiry.

Add the class path to MIDDLEWARE. Required settings: SCALEKIT_REDIRECT_URI, SCALEKIT_COOKIE_ENCRYPTION_SECRET, and either SCALEKIT_CLIENT or SCALEKIT_ENV_URL + SCALEKIT_CLIENT_ID + SCALEKIT_CLIENT_SECRET.

paramrequestHttpRequest

Incoming request.

returnsHttpResponse

Downstream response, with a new or cleared session cookie when needed.

MIDDLEWARE = [
    "scalekit.frameworks.django.ScalekitAuthMiddleware",
]

login_required

modulescalekit.frameworks.djangohttps://github.com/scalekit-inc/scalekit-sdk-python/blob/main/scalekit/frameworks/django.py

#login_required

View decorator that requires request.scalekit_user. Redirects to SCALEKIT_LOGIN_PATH?returnTo=... when the user is missing. Requires ScalekitAuthMiddleware.

paramview_funcCallable

Django view to protect.

returnsCallable

Wrapped view. Missing session → 302, never JSON 401.

from scalekit.frameworks.django import login_required

@login_required
def billing(request):
    return JsonResponse({"sub": request.scalekit_user["sub"]})

get_session

modulescalekit.frameworks.djangohttps://github.com/scalekit-inc/scalekit-sdk-python/blob/main/scalekit/frameworks/django.py

#get_session

Read-only session lookup when you also need expires_at. Most views can read request.scalekit_user instead. Does not refresh or write a cookie.

paramrequestHttpRequest

Incoming request.

returnsdict | None

{"user": ..., "expires_at": ...}, or None. Never includes access_token, refresh_token, or id_token.

from scalekit.frameworks.django import get_session

session = get_session(request)
if session:
    print(session["user"]["sub"], session["expires_at"])
