Django注册页面将不会显示在/accounts/signup/处配置不正确的产品

Question

我正在通过威廉文森特为初学者的Django工作。你知道吗

当我尝试访问http://localhost:8000/accounts/signup/时，出现了以下错误：

Internal Server Error: /accounts/signup/

This is the source code for the particular chapter I'm looking at。据我所知，我完全照搬了它。我甚至检查了压痕是否正确，看不出任何问题。你知道吗

关于这件事我有什么要查的吗？你知道吗

Answer 1

结果是打字错误。在我看来，我有from_class而不是form_class。你知道吗

应该是这样的：

class SignUpView(generic.CreateView):
    form_class = UserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'signup.html'
