django-class-based-auth-views

django-class-based-auth-views is 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 only LoginView is implemented. The others will follow.

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

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)
