22 Change password

Now that we have a profile page (added in Chapter 21) we can add in new functionality there such as allowing the user to change their password.

View

from django.views.generic import CreateView, UpdateView, DeleteView, FormView

from django.contrib.auth.forms import SetPasswordForm
from django.contrib.auth import authenticate, login

...

class ProfileView(LoginRequiredMixin, NoteMixin, FormView):
    template_name = 'note/profile.html'
    form_class = SetPasswordForm
    success_url = reverse_lazy('note:index')

    def get_context_data(self, **kwargs):
        context = super(ProfileView, self).get_context_data(**kwargs)

        try:
            api_key_obj = ApiKey.objects.get(user=self.request.user)
            api_key = api_key_obj.key
        except ApiKey.DoesNotExist:
            api_key = None

        context.update({
            'api_key': api_key
        })
        return context

    def get_form_kwargs(self):
        """ Our form requires the user. """

        kwargs = super(ProfileView, self).get_form_kwargs()
        kwargs.update({
            'user': self.request.user,
        })

        return kwargs

    def form_valid(self, form):
        form.save()

        username = self.request.user.username
        password = self.request.POST['new_password2']

        # If we don't re-authenticate with the new password the user will get logged out.
        user = authenticate(username=username, password=password)
        login(self.request, user)

        return super(ProfileView, self).form_valid(form)

If the user provides a bad password (such as the fields not matching) the page will report the error to them. But if the user successfully changes their password they do not get an indication, which is not great UX. Can you extend this to add a notification?
