Question

我正在尝试使用DRF创建银行系统。我需要在用户填写注册详细信息后立即自动为其分配一个帐号。除此之外，如果我没有正确的提问技巧，请原谅我。

我正在使用django --version 2.2.3

models.py

class AccountDetails(models.Model):
    GENDER_CHOICE = (
        ("M", "Male"),
        ("F", "Female"),
    )
    user = models.OneToOneField(
        User,
        related_name='account',
        on_delete=models.CASCADE,
    )
    account_no = models.AutoField(
        unique=True,
        primary_key=True,
        null=False,
        validators=[
            MinValueValidator(10000000),
            MaxValueValidator(99999999)
        ]
    )

views.py

def register_view(request):
    if request.user.is_authenticated:
        return redirect("home")
    else:
        user_form = UserRegistrationForm(
            request.POST or None,
        )
        account_form = AccountDetailsForm(
            request.POST or None,
            request.FILES or None
        )
        address_form = UserAddressForm(
            request.POST or None
        )

        if user_form.is_valid() and account_form.is_valid() and address_form.is_valid():
            user = user_form.save(commit=False)
            account_details = account_form.save(commit=False)
            address = address_form.save(commit=False)
            password = user_form.cleaned_data.get("password1")
            user.set_password(password)
            user.save()
            account_details.user = user
            account_details.save()
            address.user = user
            address.save()
            new_user = authenticate(
                account_no=user.account_no, password=password
            )
            login(
                request, new_user, backend='accounts.backends.AccountNoBackend'
            )
            messages.success(
                request,
                '''Thank You For Creating A Bank Account {}.
                Your Account Number is {}, Please use this number to login
                '''.format(new_user.full_name, new_user.account_no))

            return redirect("home")

        context = {
            "title": "Create a Bank Account",
            "user_form": user_form,
            "account_form": account_form,
            "address_form": address_form,
        }

        return render(request, "accounts/register_form.html", context)

以下是输出：

AttributeError at /accounts/register/
'AnonymousUser' object has no attribute '_meta'

错误指出： views.py：

#request, new_user, backend='accounts.backends.AccountNoBackend'

我希望将重定向到交易详细信息页面。
