Django注册页面将不会显示 - 在/ accounts / signup /生成ImproperlyConfigured

Question

我正在通过William S. Vincent为Django For Beginners工作。

当我尝试访问http://localhost:8000/accounts/signup/时出现此错误：

Internal Server Error: /accounts/signup/

这是我正在查看的特定章节的源代码 。 据我所知，我已经完全复制了它。 我甚至检查过适当的缩进，看不出任何问题。

有什么我应该检查一下吗？

Answer 1

原来是一个错字。 在我看来，我有from_class而不是form_class 。

这应该是这样的：

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