django-class-based-auth-views

related packages

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)
