A reimplementation of django.contrib.auth.views as class based views.

Project description


pip install django-class-auth-views

Basic usage

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

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:
            return HttpResponseRedirect(self.get_phase_two_url())
            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)
