Джанго в стиле re-style

Question

В настоящее время я пытаюсь "оформить" мою форму. в общем, я понимаю концепцию этого, но не в тот момент:

Вот как это будет (и не работает):

class RegistrationForm(UserCreationForm):
    username = forms.CharField(required=True, label='Username', widget=forms.TextInput(attrs={'class': 'class-one-input-fields'}))
    password1 = forms.CharField(required=True, label='Password', widget=forms.PasswordInput(attrs={'class': 'class-one-input-fields'}))
    password2 = forms.CharField(required=True, label='Password confirmation', widget=forms.PasswordInput(attrs={'class': 'class-one-input-fields'}))
    pubpgp = forms.CharField(required=True, label='Public PGP Key', widget=forms.Textarea(attrs={'class': 'class-two-input-fields'}))
    captcha = CaptchaField()

    def save(self, commit=True):
        username = super(RegistrationForm, self).save(commit=False)
        username.pubpgp = self.cleaned_data['pubpgp']

        if commit:
            username.save()

        return username

views.py:

def signup (request):
    if request.method == 'POST':
        form = RegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            messages.add_message(request, messages.INFO, "Thanks for you registration, you are now able to login.")
            return redirect(reverse('post_list'))
    else:
        form = RegistrationForm()

        args = {'form': form}
        return render(request, 'registration/signup.html', args)

Я получаю ошибку:

AttributeError: Менеджер недоступен; 'auth.User' был заменен для "account.User"

в моих settings.py я установил:

AUTH_USER_MODEL = 'accounts.User'

Это текущее рабочее состояние:

class RegistrationForm(UserCreationForm):
    user = forms.CharField(required=True)

    class Meta:
        model = User
        fields = (
            'user',
            'password1',
            'password2',
            'pubpgp'
        )

    captcha = CaptchaField()

    def save(self, commit=True):
        user = super(RegistrationForm, self).save(commit=False)
        user.pubpgp = self.cleaned_data['pubpgp']

        if commit:
            user.save()

        return user

Полагаю, мне нужно как-то передать модель User в эту форму. Есть идеи о синтаксисе?
