我把谷歌应用程序引擎，创建一个Shoppinglist的官方例子，修改它，所以它会：谷歌App Engine的例子，改装
创建两个表，而不是一个Shoppinglist（接触和PhoneNumber）。 这是为了了解google如何处理两个表和Foreignkey（请参阅下面的代码）。
它显示一切直到线47：
数据= ******中国（数据= self.request.POST） DATA2 =端子（DATA2 = self.request.POST）
不知何故它不能处理该第二个“数据2”对象，并给了我和错误：
类型错误：初始化（）得到了一个意想不到的关键字参数“数据2”
为什么？ 我能做些什么才能使它工作？
谢谢你的时间。
