Question

我正在使用Cassandra DB和Django Framework，我试图从数据库中获取特定用户的部分信息，并尝试将其与用户输入进行比较，但不是返回输出，而是向我展示了一个“Unicode对象”没有属性项“错误

这是您参考的错误详情：

这是代码：

views.py

def LoginAuthPageView(request):
    if request.method == 'POST':
        form = Login(request.POST)

        if form.is_valid():
            username = form.data['username']
            password = form.data['password']

            cursor = connection.cursor()
            result = cursor.execute("SELECT salt, password FROM emergency_command_center.auth_user_model WHERE username = ?", username)

            pword_hash = hashlib.sha512(password + result['salt']).hexdigest()

            if(pword_hash == result['password']):
                return HttpResponse(pword_hash)

我做错了吗？

这个问题现在已经有些陈旧了，但是人们在搜索错误消息时仍然可以找到它：“ AttributeError：'unicode'对象没有属性'items'”

在我的情况下（youtube-dl），使用python3而不是python2解决了该问题。

可能其中一个涉及的.py文件仅使用python3-ism。

'Unicode'对象没有属性'items'
