Question

我正在尝试建立Instagram克隆。

单击“跟随”按钮将调用ajax。

我的视图定义文章保存“跟随”并返回Response对象，该对象的数据为true / false值，用于指示是否先前跟踪了用户。

错误消息

//function to show the list item
HRESULT function(datetime, strNumOfGroup, strDisributionRegion, strSpeed){

  m_count = m_hyperTerminal.GetItemCount();

  items = m_hyperTerminal.InsertItem(m_count, datetime);// Five columns in the list control

  m_hyperTerminal.SetItemText(items, 1, strNumOfGroup);
  m_hyperTerminal.SetItemText(items, 2, strCompactness);
  m_hyperTerminal.SetItemText(items, 3, strDistributionRegion);
  m_hyperTerminal.SetItemText(items, 4, strSpeed);
}

                    return Response({
                        'follow_exist': False
                    })
                else:

                    return Response({
                        'follow_exist': True
                    })
        else:
            return redirect('insta/login')

ajax

path('<username>/', insta_profile, name='profile'),

你能告诉我为什么会这样吗？

谢谢。

在您的例外情况下添加此

 return HttpResponseRedirect(reverse('insta:dashboard', args=(username,), status=HTTP_404_NOT_FOUND)

代替

    return HttpResponseRedirect(reverse('insta:dashboard'), status=HTTP_404_NOT_FOUND)
