What would you like to do?
An example for how to customize login-required (in this case, to use a session based token instead)
from django.contrib.auth import REDIRECT_FIELD_NAME
from django.shortcuts import render, resolve_url
from myapp.settings import cfg
from myapp import settings
from urllib.parse import urlparse
import uuid
def login_is_required(
function=None, login_url=None, redirect_field_name=REDIRECT_FIELD_NAME
Decorator to extend login required to also check if a notebook auth is
desired first (but you could customize this to be another check!)
def wrap(request, *args, **kwargs):
# If we are using a notebook, the user is required to provide a token
# This is just an example of what I was trying to do, you could customize this
if cfg.NOTEBOOK or cfg.NOTEBOOK_ONLY and not request.session.get("notebook_auth"):
request.session["notebook_token"] = str(uuid.uuid4())
print("Enter token: %s" % request.session["notebook_token"])
return render(request, "login/notebook.html")
# If the user is authenticated, return the view right away
if request.user.is_authenticated:
return function(request, *args, **kwargs)
# Otherwise, prepare login url (from django user_passes_test)
path = request.build_absolute_uri()
resolved_login_url = resolve_url(login_url or settings.LOGIN_URL)
login_scheme, login_netloc = urlparse(resolved_login_url)[:2]
current_scheme, current_netloc = urlparse(path)[:2]
if (not login_scheme or login_scheme == current_scheme) and (
not login_netloc or login_netloc == current_netloc
path = request.get_full_path()
from django.contrib.auth.views import redirect_to_login
return redirect_to_login(path, resolved_login_url, redirect_field_name)
wrap.__doc__ = function.__doc__
wrap.__name__ = function.__name__
return wrap
from myapp.decorators import login_is_required
def index(request):
return render(request, "main/index.html")
