AttributeError:'Message'对象没有属性'put'

Question

以下代码:

class Message(db.Model):
    content = db.StringProperty()


class Message(webapp2.RequestHandler):

    def get(self):
        doRender(self,'message.htm')

    def post(self):

        message = Message()
        message.content = self.request.get('content')
        message.put();
        self.redirect('/view') 

给我以下错误消息:

AttributeError: 'Message' object has no attribute 'put'

我究竟做错了什么？

Answer 1

那不是你怎么做的.

你.put是模特,而不是Message班级.您需要首先使用db或ndb创建模型.

对于你的例子:

class Greeting(ndb.Model):
  content = ndb.StringProperty()
  date = ndb.DateTimeProperty(auto_now_add=True)

def post(self):

    message = Greeting()
    message.content = self.request.get('content')
    message.put();

    self.redirect('/view')
