Python 谷歌应用程序引擎：提取所选单选按钮的值

我正在构建一个应用程序，允许用户创建调查并对调查中的问题进行投票。现在，这些问题的答案将存储在数据存储中，以便我最终可以分析结果。但是，我无法找到一种方法来提取用户选择的单选按钮的值。每个问题有三个选项，所有选项都由单选按钮表示

代码如下：

main.py

import os
import webapp2
import jinja2
from google.appengine.ext import db
from random import randint

template_dir = os.path.join(os.path.dirname(__file__), 'templates')
jinja_env = jinja2.Environment(loader = jinja2.FileSystemLoader(template_dir), autoescape=True)

class Handler(webapp2.RequestHandler):
    def write(self, *a, **kw):
        self.response.out.write(*a, **kw)
    def render_str(self, template, **params):
        t = jinja_env.get_template(template)
        return t.render(params)
    def render(self, template, **kw):
        self.write(self.render_str(template, **kw))

class Survey(db.Model):
    vam_id = db.StringProperty()
    subject = db.StringProperty(required = True)
    description = db.TextProperty(required = True)
    created = db.DateTimeProperty(auto_now_add = True)
    q1 = db.TextProperty(required = True)
    o11 = db.TextProperty(required = True)
    o12 = db.TextProperty(required = True)
    o13 = db.TextProperty(required = True)
    q2 = db.TextProperty(required = True)
    o21 = db.TextProperty(required = True)

    o42 = db.TextProperty(required = True)
    o43 = db.TextProperty(required = True) 
    q5 = db.TextProperty(required = True)
    o51 = db.TextProperty(required = True)
    o52 = db.TextProperty(required = True)
    o53 = db.TextProperty(required = True)

现在，无论我从列出的三个选项中选择了什么，存储在数据存储中的值都是“开”，这表示选择了单选按钮组中的单选按钮。如何将用户选择的实际选项存储到数据存储中

您尚未为表单元素指定任何

值。我想你想要：

<input type="radio" name="q3" value="{{su.o31}}" />{{su.o31}}<br>

{{su.o31}}


现在，您可以检索它的
值
。既然您已经在使用jinja，我建议您使用WTForms包来简化这一切
