Question

我想比较数据库中的两个Twilio数字。因为它们以“+”开头，所以我不确定如何比较它们。这是我收集数据并将数字保存到数据库的代码。我正在尝试检查数据库中的传入号码。

if request.method == 'POST':
    a = Number.objects.all()
    from_number = request.POST.get('From', None)
    u = Number(cell_number=from_number)
    u.save()
    msg_new = 'We recorded your number as %s' % (from_number)
    m = Response()
    m.message(msg_new)
    return m

一如既往，感谢您的帮助！

更新

根据我收到的答案，我更新了代码。它有效！

 if request.method == 'POST':
        from_number = request.POST.get('From', None)
        if Number.objects.filter(cell_number=from_number).exists():
            msg = "We already have your number recorded in our system."
            r = Response()
            r.message(msg)
            return r
        else:
            u = Number(cell_number=from_number)
            u.save()
            msg_new = 'We recorded your number as %s' % (from_number)
            m = Response()
            m.message(msg_new)
            return m

我假设您所指的Twilio数字以标准https://peekandpoke.wordpress.com/2015/02/26/dancing-the-lambada-with-aws-lambda-or-sending-emails-on-s3-events/格式存储，该格式已标准化以删除所有空格等。

如果是这样，那么您需要做的就是在数据库中查找数字。因此，要查看数字是否已经存在，您可以这样做：

if Number.objects.filter(cell_number='+4412349834024').exists():
    # The number already exists in the database
else:
    # The number doesn't exist in the database, go ahead and add it

如果您要以这种方式查询，则可能需要确保将cell_number字段编入索引。
