使用UserPassesTestMixin（基于类的视图）和重定向

Question

我试图改为使用基于类的视图，所有我最终都使用默认的403 Forbidden页面.. mixin类的顺序是否正确？代码是否在get / post中被使用-as或者是否绕过了所有内容并且发生了默认的403重定向？

到目前为止看到的所有工作示例，仅指向基于函数的视图中的装饰器@login_required，并使用请求对象重定向到登录页面。 documentation提供了一些提示，但我无法使用下面的代码。也可以使用错误堆栈。

码：

 class UserIsAdminMixin(UserPassesTestMixin):
        def test_func(self):
            return request.user.groups.filter(name='CustomAdmin').exists()

    class CustomAdminView(LoginRequiredMixin, UserIsAdminMixin, TemplateView):
        template_name = 'template.html'
        # login_url = '/login/'
        # redirect_field_name = 'my_link_name'

        def get(self, request):
            form = CustomForm()
            # This does not work neither does setting up login_url 
            if not request.user.is_authenticated or not request.user.is_staff or not self.request.user.groups.filter(name='CustomAdmin').exists():
                return redirect('%s?next=%s' % (settings.LOGIN_URL, request.path))

如果上述方法不起作用，我愿意尝试this solution

根据this answer，您可以使用handle_no_permission(self):来处理重定向URL。

只是：

def handle_no_permission(self):
    return redirect('users:create-profile')
