Question

关于标题，我在Django中遇到了验证问题。当我注销时出现此错误，似乎系统正在寻找用户ID，但是，因为我清除了注销的会话（无论如何都无法确定，我将django auth用于登录/注销系统），它在会话中找不到具有相同ID的任何用户，并且给了我这个错误。因此，我尝试删除了我在代码中拥有的所有用户调用，但仍然无法使用。

以下是完整的错误日志。

如果我删除了“ {％request.user.is_authenticated％}”，我可以登录从我的模板。然后，我必须再次插入它以显示已登录用户的菜单，并且一切正常，直到我再次执行注销并再次以相同错误运行。

我尝试了几件事，但仍然无法弄清正在发生的事情以及在哪里可以找到问题所在。

我是django的新手，几天来我正试图解决这个问题，如果有人能给我正确的方向来解决这个问题，将不胜感激。

Answer 1

我找到了解决方法！

问题出在存储会话变量并检查会话密钥。

如果我没有弄错，则会话密钥“ voucher_id”存储在auth_user_id会话中，这是由于该会话正在寻找存储密钥的user_id所致。

我将在此处发布为解决此问题而对代码进行的更改，在我的凭证context.py中（我正在检查凭证代码是否在会话中）：

之前：

if ['voucher_id'] not in request.session:
        voucher_id = request.session.get('voucher_id')
        try:
            code = Voucher.objects.get(id=voucher_id)
        except Voucher.DoesNotExist:
            code = None
    else:
        None

固定代码：

if 'voucher_id':
        voucher_id = request.session.get('voucher_id')
        try:
            code = Voucher.objects.get(id=voucher_id)
        except Voucher.DoesNotExist:
            code = None
    else:
        None

对于我使用的注销（关于ozgur的答案，发布在这里Runtime error when trying to logout django）：

from django.contrib.auth import logout as django_logout


@login_required
def logout(request):
    django_logout(request)
    return  HttpResponseRedirect(reverse('index'))

希望这种逻辑对遇到此问题的其他人可能有用，我在django session文档中进行了深入而深入的阅读，以找出答案。

谢谢拉尔夫（Ralf）花时间尝试找出问题所在，并在正确的方向上发给我，寻找会议中的问题。
