Question

我正尝试使用基于类的视图，而所有这些最终都显示默认的403 Forbidden页面。.mixin类的顺序正确吗？代码是否会像在get / post中那样被使用，还是会跳过所有内容并发生默认的403重定向？

到目前为止，所有可用的示例都仅指向基于函数的视图中的装饰器@login_required，并使用request对象重定向至登录页面。 documentation提供了一些技巧，但我无法将其与下面的代码一起使用。将错误堆栈也放入。

检查

 "GET / HTTP/1.1" 200 2580
Forbidden (Permission denied): /app/custom-view
Traceback (most recent call last):

    response = get_response(request)

    response = self.process_exception_by_middleware(e, request)

    raise PermissionDenied(self.get_permission_denied_message())
django.core.exceptions.PermissionDenied

代码：

 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))

如果上述方法无效，我愿意尝试this solution

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

简单地：

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

使用UserPassesTestMixin（基于类的视图）并重定向
