使用 UserPassesTestMixin（基于类的视图）和重定向

Question

我正在尝试改用基于类的视图，而我最终得到的是默认的 403 禁止页面。混合类的顺序是否正确？代码甚至会被使用 - 就像在 get/post 中一样，还是会绕过所有内容并发生默认的 403 重定向？

到目前为止看到的所有工作示例，仅在基于函数的视图中指向装饰器 @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，但我无法让它与下面的代码一起使用。也放入错误堆栈。

检查

 "GET / HTTP/1.1" 200 2580

    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))

如果上述方法不起作用，我愿意尝试this solution

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

简单地说：

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