Question

这里是Django的新手。我正在设置注册页面，我想确保当前登录的用户无法创建新帐户。

到目前为止，我有一个这样的表格：

class RegisterView(FormView):
    template_name = 'users/register_user.html'
    success_url = 'thank_you'

    def get(self, request):
        if request.user.is_authenticated():
            # If a user is logged in, redirect them to a page informing them of such
            return render(request, 'users/already_logged_in.html')
        else:
            # would like to direct the user to the normal registration page

    def post(self, request):
        user_form = UserCreateForm(request.POST)
        if user_form.is_valid():
            username = user_form.clean_username()
            password = user_form.clean_password2()
            user_form.save()
            user = authenticate(username=username,
                                password=password)
            login(request, user)
            return render(request, 'home.html')
        return render(request, 'register_user.html', {'form': user_form})

我怀疑我可能不得不使用mixins（我也对它们的含义感到困惑）所以如果它们是解决方案的一部分请稍微扩展一下。

在“其他”之后我应该包括什么才能让它通过通常的注册页面？

提前感谢您的帮助。

只返回父FormView将返回的内容

def get(self, request):
    if request.user.is_authenticated():
        # If a user is logged in, redirect them to a page informing them of such
        return render(request, 'users/already_logged_in.html')
    else:
        return super(RegisterView, self).get(request)

您需要在视图中设置form_class，而不是在帖子中设置方法，请查看django文档，了解如何使用FormView https://docs.djangoproject.com/en/1.7/ref/class-based-views/generic-editing/#formview
