django-ticketoffice provides one-shot authentication (a.k.a. temporary credentials) utilities for Django. It lets you create and manage tickets that allow users to perform one action on the website. As an example, Django could use it for the "password reset" action, where users authenticate using a temporary token.

Restrict some URL to guests with valid invitation tickets:

from django.conf.urls import patterns, url
from django_ticketoffice.decorators import invitation_required, stamp_invitation

@invitation_required(place=u'louvre', purpose=u'visit')
@stamp_invitation  # Mark invitation as used right **after** view execution.
def visit_louvre(request):
    ticket = request.cache['invitation']  # Set by `invitation_required`.
    return u'Welcome to the Louvre museum {guest}'.format(
        guest=ticket.data['first_name'])

urlpatterns = patterns('', url('^louvre$', visit_louvre, name='louvre'))

Create and deliver tickets for this resource:

from django.utils.timezone import now
from django_ticketoffice.models import Ticket

ticket = Ticket(place=u'louvre', purpose=u'visit')
ticket.set_password(u'I love Paris')  # Encrypted in database.
ticket.expiry_datetime = now() + timedelta(days=5)  # Optional.
ticket.data = {'first_name': u'Léonard'}  # Optional.
ticket.save()

credentials = {'uuid': ticket.uuid, 'password': u'I love Paris'}
visit_url = reverse('louvre') + '?' + urlencode(credentials)

django-ticketoffice focuses on authentication. It does not send invitation emails. You may check django-mail-factory about sending emails.

django-ticketoffice is, at the moment, a proof-of-concept: it delivers basic features in order to create tickets and to use them in views. It works (you can use it), but it may lack some features (ideas are welcome), and it may change (improve) quite a bit. That said, maintainers will take care of release notes and migrations.
