关于python：如果页面上有多个表单而没有提交按钮Django 1.10，如何传递表单ID？

How to pass form id if there are several forms on page and no submit buttons Django 1.10?

我有一页问题清单。他们每个人都有带有"是"、"可能"、"否"选项的单选按钮窗体。通过选择提交此表单。网址：http://prntscr.com/embo1m

我不明白如何把问题ID和它的形式联系起来。如何将其置于有响应的视图中？

把我的表格改成

1 2	class AnswerForm(Form): choice = ChoiceField(label='', widget=RadioSelect, choices=ANSWERS)

。

但是在表单中没有来自响应的隐藏输入…
