使用数据存储的简单GAE表单中的datatype异常
使用数据存储的简单GAE表单中的datatype异常
提问于 2012-04-05 00:53:15
我是GAE的新手，正在尝试我的第一个示例应用程序。我已经编写了一个简单的HTMl表单。单击submit时，需要将字段中的详细信息保存在数据存储中。
我的问题是我得到了数据类型异常，我不知道哪里出错了。
import cgi

# )
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):

BadValueError: Property champion_phone_number must be an int or long, not a unicode我绝对确定答案会让我成为faceplam，但我现在就是不明白。我相信我放入了正确的db模型。此外，我是否在webform表单域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，也会得到相同的错误。
编辑: OP here。如果有人对我所做的事情感兴趣，在我将所有必需的字段数据转换为int之后，我发现了另一个错误。如果我的任何字段有空值，我就会得到valueerror错误提示。现在，我想把所有的数据输入验证都放在客户端。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:

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。如果需要该属性是另一种类型(如champion_phone_number )，则需要显式地将其转换为int()
