我正在关注 DjangoBook 教程，但在第 14 章（用户注册）中遇到了问题

在django.contrib.auth.forms中有一个UserCreationForm类。我正在尝试创建一个基于UserCreationForm调用的新类RegisterForm

这是我RegisterForm在django.contrib.auth.forms中的课程

class RegisterForm(UserCreationForm):
    email = forms.EmailField(label="Email")
    fullname = forms.CharField(label="Full name")

    class Meta:
        model= User
        fields = ("username","fullname","email",)

这是视图功能

def register(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)
        if form.is_valid():
            new_user = form.save()
            return HttpResponseRedirect("/books/")
    else:
        form = RegisterForm(UserCreationForm)
    return render(request, "registration/register.html", {
        'form': form,
    })

我不知道为什么我得到一个 ImportError ，它指出我无法RegisterForm在我的视图中导入名称，有人可以帮助我谢谢。

这是我的堆栈跟踪

从Django 1.5开始，模块中没有这种形式django.contrib.auth.forms.

您可能希望使用能够为您突出显示此类内容的编辑器。比如PyCharm。

不过，重点是，您至少应该对要学习的内容有基本的Python了解Django。你看，这些陈述

class RegisterForm(UserCreationForm)    
    ...
# And then:
form = RegisterForm(UserCreationForm)

从 Python 的角度来看几乎没有任何意义。

您正在编写 Python 代码。在 Python 中。你必须学习 Python。是的，可以走另一条路，但要困难得多。
