Python 使用数据存储的简单GAE表单中的数据类型异常

我是GAE的新手，正在尝试我的第一个示例应用程序。 我已经写了一个简单的HTMl表单。单击提交后，字段中的详细信息需要保存在数据存储中

我的问题是我遇到了数据类型异常，我不知道哪里出了问题

import cgi
import datetime
import urllib
import wsgiref.handlers
import os
from google.appengine.ext.webapp import template

from google.appengine.ext import db
from google.appengine.api import users
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app

class Champion(db.Model):
    champion_first_name = db.StringProperty()
    champion_last_name = db.StringProperty()
    champion_email = db.EmailProperty()
    champion_phone_code = db.IntegerProperty()
    champion_phone_number = db.IntegerProperty()
    diabetic_first_name = db.StringProperty()
    diabetic_last_name = db.StringProperty()
    diabetic_age = db.IntegerProperty()
    diabetic_gender = db.StringProperty()
    diabetic_email = db.EmailProperty()
    diabetic_phone_code = db.IntegerProperty()
    diabetic_phone_number = db.IntegerProperty()
    diabetic_city = db.StringProperty()
    diabetic_zipcode = db.IntegerProperty()
    diabetic_since = db.IntegerProperty()
    diabetic_relationship = db.StringProperty()
    checkup_date = db.DateProperty ()
    md_advert_feedback = db.StringProperty()
    timestamp = db.DateTimeProperty(auto_now_add=True)

class MainPage(webapp.RequestHandler):
    def get(self):
        template_values = {}
        path = os.path.join(os.path.dirname(__file__), 'main.html')
        self.response.out.write(template.render(path, template_values))

    def post(self):
        pledge_data = Champion(champion_first_name = cgi.escape(self.request.get('champ_first_name')),
                    champion_last_name = cgi.escape(self.request.get('champ_last_name')),
                    champion_email = cgi.escape(self.request.get('champ_email')),
                    champion_phone_code = cgi.escape(self.request.get('champ_phone_code')),
                    champion_phone_number = cgi.escape(self.request.get('champ_phone_number')),
                    diabetic_first_name = cgi.escape(self.request.get('diab_first_name')),
                    diabetic_last_name = cgi.escape(self.request.get('diab_last_name')),
                    diabetic_age = cgi.escape(self.request.get('diab_age')),
                    diabetic_gender = cgi.escape(self.request.get('diab_gender')),
                    diabetic_email = cgi.escape(self.request.get('diab_email')),
                    diabetic_phone_code = cgi.escape(self.request.get('diab_phone_code')),
                    diabetic_phone_number = cgi.escape(self.request.get('diab_phone_number')),
                    diabetic_city = cgi.escape(self.request.get('diab_city')),
                    diabetic_zipcode = cgi.escape(self.request.get('diab_zip')))
                    # diabetic_since = cgi.escape(int(self.request.get('diab_since'))))
                    # diabetic_relationship = cgi.escape(self.request.get('diab_relationship')),
                    # md_advert_feedback = cgi.escape(self.request.get('md_ad_feedback'))
                    # checkup_date = cgi.escape(self.request.get('checkup_date')),
                    # )

        pledge_data.put()


application = webapp.WSGIApplication([
    ('/', MainPage),
], debug=True)


def main():
  run_wsgi_app(application)


if __name__ == '__main__':
  main()

我得到的错误是

Traceback (most recent call last):
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\ext\webapp\_webapp25.py", line 703, in __call__
    handler.post(*groups)

    % (self.name, type(value).__name__))
BadValueError: Property champion_phone_number must be an int or long, not a unicode

我绝对肯定答案会让我脸红，但我现在不明白。我相信我已经输入了正确的db模型。 另外，我是否在webform字段中实际输入任何数据也没有区别。即使我将字段保留为空，然后单击submit，也会出现相同的错误

编辑： 在这里。 以防有人对我所做的事感兴趣； 将所有必需的字段数据转换为int后，我发现了另一个错误。 如果我的任何字段有空值，我将得到valueerror-eception。 现在，我想将所有数据输入验证留在客户端。 所以我把代码改成了

def post(self):
    pledge_data = Champion()
    try:
        pledge_data.champion_first_name = cgi.escape(self.request.get('champ_first_name'))
        pledge_data.champion_last_name = cgi.escape(self.request.get('champ_last_name'))
        pledge_data.champion_email = cgi.escape(self.request.get('champ_email'))
        pledge_data.champion_phone_code = int(cgi.escape(self.request.get('champ_phone_code')))
        pledge_data.champion_phone_number = int(cgi.escape(self.request.get('champ_phone_number')))
        pledge_data.diabetic_first_name = cgi.escape(self.request.get('diab_first_name'))
        pledge_data.diabetic_last_name = cgi.escape(self.request.get('diab_last_name'))
        pledge_data.diabetic_age = int(cgi.escape(self.request.get('diab_age')))
        pledge_data.diabetic_gender = cgi.escape(self.request.get('diab_gender'))
        pledge_data.diabetic_email = cgi.escape(self.request.get('diab_email'))
        pledge_data.diabetic_phone_code = int(cgi.escape(self.request.get('diab_phone_code')))
        pledge_data.diabetic_phone_number = int(cgi.escape(self.request.get('diab_phone_number')))
        pledge_data.diabetic_city = cgi.escape(self.request.get('diab_city'))
        pledge_data.diabetic_zipcode = int(cgi.escape(self.request.get('diab_zip')))
        pledge_data.diabetic_since = int(cgi.escape(self.request.get('diab_since')))
                # diabetic_relationship = cgi.escape(self.request.get('diab_relationship')),
                # md_advert_feedback = cgi.escape(self.request.get('md_ad_feedback'))
                # checkup_date = cgi.escape(self.request.get('checkup_date')),
                # )
    except ValueError:
        pass

    pledge_data.put()

快速修复方法是显式强制转换，例如：

...
champion_phone_number = int(cgi.escape(self.request.get('champ_phone_number'))),
...

---

所有请求参数都是字符串。如果您需要属性是另一种类型，如champion\u phone\u number，则需要将其显式转换为int（）

+1，以包含相关代码示例和完整回溯。谢谢。谢谢您添加python标记。忘了不用担心。在他们添加Go和Java支持之前，这是不必要的：DWY您想将电话号码存储为整数吗？这似乎是一个非常糟糕的主意（tm）。电话号码不是整数——试图以这种方式存储它们是一个糟糕的主意。同样，您应该在输出时进行转义，而不是在输入时进行转义（如在上一个代码段中）diabetic_-since=cgi.escape（int（self.request.get（'diab_-since'）））这是我第一次遇到错误时尝试的方法。我在cgi.escape子句中使用了int/脸掌，没关系！你不是你的代码。我们都做这样的事。出去，抓住下一个虫子！我猜：这将是一个更难解决的问题。
