=============================

django-class-based-auth-views

=============================

related packages

================

* `django-password-reset `_ has class based views to reset

  forgotten passwords by email confirmation.

A reimplementation of ``django.contrib.auth.views`` as class based views. Hopefully at some point this project or

something similar will make it into django proper.

Currently ``LoginView`` and ``LogoutView`` are implemented.

Installation

============

::

    pip install django-class-based-auth-views

Basic usage

===========

Instead of including ``django.contrib.auth.login`` into your ``urls.py``, just use the one provided by this project.

``urls.py``::

    from class_based_auth_views.views import LoginView, LogoutView

    urlpatterns = patterns('',

        url(r'^login/$', LoginView.as_view(form_class=EmailAsUsernameAuthenticationForm), name="login"),

        url(r'^logout/$', LogoutView.as_view(), name="logout"),

    )

Be aware that the logout view requires a ``POST`` to actually logout. So the ``registration/logout.html`` template

should contain a form with a submit button.

Extending LoginView Example

===========================

Now that LoginView is based on generic class based views it is much easier to extend. Say you need to implement a

2 step login procedure with a one time password::

    from django.contrib.auth import login

    class PhaseOneLoginView(LoginView):

        def form_valid(self, form):

            """

            Forces superusers to login in a 2 step process (One Time Password). Other users are logged in normally

            """

            user = form.get_user()

            if user.is_superuser:

                self.save_user(user)

                return HttpResponseRedirect(self.get_phase_two_url())

            else:

                login(self.request, user)

                return HttpResponseRedirect(self.get_success_url())

        def get_phase_two_url(self):

            return reverse('phase_two_login')

        def save_user(self, user):

            self.request.session['otp_user'] = user

    class PhaseTwoLoginView(FormView):

        form_class = OTPTokenForm

        def get_user(self):

            return self.request.session.get('otp_user', None)

        def clean_user(self):

            if 'otp_user' in self.request.session:

                del self.request.session['otp_user']

        def form_valid(self, form):

            code = form.cleaned_data.get('code')

            user = self.get_user()

            login(request, user)
