Unable to store data in appengine datastore

I'm trying to make a simple appengine app where users login through Github and their public information(only userid) is stored in the datastore. Here is the simple script which I wrote: 

import webapp2
from google.appengine.ext import db

import json
import requests

form="""
<html>
<body>
<a href="https://github.com/login/oauth/authorize?state=myapp&redirect_uri=(redirection uri)&client_id=(myclientid)&scope=user">Login</a>
</body>
</html>
"""

class Userdata(db.Model):
    userid = db.StringProperty()

class Devhandler(webapp2.RequestHandler):
    def get(self):
        url_get = self.request.GET
        state=url_get['state']
        code=url_get['code']
        self.response.headers["Content-Type"] = "application/json"
        url = 'https://github.com/login/oauth/access_token?client_id=(clientid)&client_secret=(my secretclient id)&redirect_uri=(redirect uri)&code='+code
        r=requests.post(url)
        req=str(r.content)
        access_token = ""
        i=13
        while(req[i]!='&'):
            access_token = access_token + req[i]
            i = i + 1

        result_url = 'https://api.github.com/user?access_token='+str(access_token)
        result = requests.get(result_url)
        fd = json.loads(result.content) #fd contains the user data in json format!
        userid = fd['login'] 
        user_instance = Userdata(userid=userid)
        user_instance.put()
        self.redirect('/welcome')


class Profilehandler(webapp2.RequestHandler):
    def get(self):
        self.response.out.write("Welcome!")



app = webapp2.WSGIApplication([
    ('/',Mainhandler),
    ('/dev',Devhandler),
    ('/welcome',Profilehandler)
    ],debug=True)

When I run the above code,everything works fine but the only problem is, I'm unable to store the user data. When I open the appengine data store viewer, I find nothing(no users in the data store!). What is the problem with the code? Why am I unable to store user data?

PS: There is not problem with my account, I can store data in other projects easily. I feel glad if someone can help me out!!

You might be checking the user data in SDK Console data viewer. Try checking the data store at https://appengine.google.com/dashboard . You would surely find your data there if there is no bug in your code.

  • Your Mainhandler dose not exist in the code.
  • Why you need request ?
  • It's better for your project if you use directly ndb in place of db.
  • Are you shure you don't refresh the page /welcome in place of / ?

If your implement this, the string value should be store in the datastore. If not you have another problem.

class Userdata(db.Model):
  userid = db.StringProperty()

class Mainhandler(webapp2.RequestHandler):
  def get(self):
    user_instance = Userdata(userid="test")
    user_instance.put()
    self.redirect('/welcome')

Add a logging in your code to see the content of userid and force this content with str before storing. user_instance = Userdata(userid=str(userid))

if the conversion in str is not possible it's a character encoding problem.

Are you sure get method of davhandle class is getting called? Use some logging to test it. just incase if you dont know:

import logging
logging.info('anythng')
