Python Django 1.6：多值错误

我正在尝试实现一个平均时间特性，允许用户输入等待医生的时间。但我不断地遇到这个错误，我不知道如何修复它。我已经试过研究了，但我还是很困惑

问题是post对象中没有变量“time”

我的建议是：

1） 通过打印或写入文件，查看post对象的外观。（我想您可能正在使用get而不是post。）

2） 当您处理用户输入的数据时，总是希望它可能与预期的不同。（恶意用户或爬行器可能正在抓取您的站点。）而是使用：

time = post.get('time')
if time:
    time = escape()
else:
    # No time value was submitted ....

正如cchristelis所说，错误是因为您的POST数据中没有

time

值

真的，对于这类事情，你应该使用Django的。这是验证用户输入并对其进行处理的适当工具

如果我使用您上面所述的内容，我得到的全局名称“post”没有定义。我想您会意识到它必须在您的

post=请求之后发生。post
