Requirements

• Django

Installation

1. Install python library using pip: pip install django-cerberus
2. Add cerberus to INSTALLED_APPS in your Django settings file

    template_name = 'example/login.html'
    form_class = AuthenticationForm

    @method_decorator(watch_logins)
    def dispatch(self, request, *args, **kwargs):
        if request.user.is_authenticated():
            return redirect(settings.LOGIN_REDIRECT_URL)
        return super(LoginView, self).dispatch(request, *args, **kwargs)

    def form_valid(self, form):
        user = form.get_user()
        login(self.request, user)
        return super(LoginView, self).form_valid(form)

    def get_success_url(self):
        return reverse('logged_in')

Settings

CERBERUS_MAX_ATTEMPTS

Number of max failed login attempt. Default: 5.

CERBERUS_LOCKOUT_TIME

Number of seconds after the failed login attempts are forgotten in seconds. Default: 600.

Model

Each lockout model instance contains username, number of failed login attempts, IP address, user agent details, GET and POST parameters, information if lockout is locked (user tried to log in with wrong credentials at least CERBERUS_MAX_ATTEMPTS times) and if lockout is expired (based on CERBERUS_LOCKOUT_TIME).

Template

You can override cerberus/lockout.html template if you wish. There is lockout instance and lockout_time variable (CERBERUS_LOCKOUT_TIME) available in template context.
