Django SignUp view challange

I think my problem is that I can't get the user, I tried getting "username" and "password" from the post data and that didn't work.

accounts/views.py 
from django.contrib.auth import authenticate, login
from django.core.urlresolvers import reverse_lazy
from django.views import generic

from . import forms


class SignUp(generic.CreateView):
    form_class = forms.UserCreateForm
    template_name = 'accounts/signup.html'
    success_url = reverse_lazy('products:list')

    def form_valid(self, user):
        username = self.request.POST['username']
        password = self.request.POST['password']
        user = authenticate(username=username, password=password)
        if user is not None:
            if user.is_active:
                login(self.request, user)
        return super().form_valid(form)

I have changed my code, I think this might be closer to the solution but the code doesn't work still.

from django.contrib.auth import authenticate, login
from django.core.urlresolvers import reverse_lazy
from django.views import generic

from . import forms


class SignUp(generic.CreateView):
    form_class = forms.UserCreateForm
    template_name = 'accounts/signup.html'
    success_url = reverse_lazy('products:list')

    def form_valid(self, form):
        username = form.cleaned_data['username']
        password = form.cleaned_data['password1']
        user = authenticate(username=username, password=password)
        if user is not None:
            login(self.request, user)
        return super().form_valid(form)

You are very close. I had to research the answer. See Lewis Cowles' answer on Oct 6, 2016 (from this thread]

In brief, add a line at the top of the method:

res = super().form_valid(form)

Then change the return statement to:

return res
