Receive and Set Session Values using Flask and KVSession

gistfile1.py

from flask import Flask, request, make_response, session
from flaskext.kvsession import KVSessionExtension
from datetime import datetime, timedelta
from twilio import twiml
import json

import redis
from simplekv.memory.redisstore import RedisStore

SECRET_KEY = 'a secret key'

#Because this is new code, lets use the preferred RedisStrict implementation
store = RedisStore(redis.StrictRedis(host = '127.0.0.1', port = 6379, db = 0))

app = Flask(__name__)
app.config.from_object(__name__)

KVSessionExtension(store, app)

@app.route("/sms")
def converse():

    messagecount = int(session.get('messagecount',0))
    messagecount += 1

    username = session.get('username', locateUsername( request.args.get('From') ) )

    session['messagecount'] = str(messagecount)
    session['username'] = username

    twml = twiml.Response()
    twml.sms("Hello " + username + ".  You've sent " + str(messagecount) + " messages in this conversation so far")

    resp = make_response(str(twml))

    return resp

if __name__ == "__main__":
    app.debug = True
    app.run()

I don't see how you stored the session in the database. I'm interested in use SQLAlchemy. Would this follow the same steps?

I couldn't get this to work until I changed "from flaskext.kvsession" to "from flask.ext.kvsession", just a note. Probably something that has changed since this was published originally.
