something wrong with flask-login and flask-openid when i follow miguel's tutorial

this is the views.py

from flask import flash, redirect, render_template, session, url_for, request, g
from flask.ext.login import login_user, logout_user, current_user, login_required
from app import app, db, lm, oid
from .forms import LoginForm
from .models import User

@lm.user_loader
def load_user(id):
    return User.query.get(int(id))

@app.before_request
def before_request():
    g.user = current_user


@app.route('/')
@app.route('/index')
@login_required
def index():
#user = {'nickname': 'Miguel'} #fake user
    user = g.user
    posts = [ # fake array of posts
    {
        'author': { 'nickname': 'John' },
        'body': 'Beautiful day in portland!'        

    },
    {
        'author': { 'nickname': 'Susan'},
        'body': 'The Avengers movie was so cool!'
    }
    ]
    return render_template("index.html",
                        title = 'Home',
                        user = user,
                        posts = posts)


@app.route('/login', methods = ['GET', 'POST'])
@oid.loginhandler
def login():
    if g.user is not None and g.user.is_authenticated:
        return redirect(url_for('index'))
    form = LoginForm()
    if form.validate_on_submit():
        session['remember_me'] = form.remember_me.data
        return oid.try_login(form.openid.data, ask_for=['nickname', 'email'])
        #flash('Login requested for OpenID="' + form.openid.data + '", remember_me=' + str(form.remember_me.data))
        #return redirect('/index')
    return render_template('login.html',
                        title = 'Sign In',
                        form = form,
                        providers = app.config['OPENID_PROVIDERS'])

@app.route('/logout')
def logout():
    logout_user()
    return redirect(url_for('index'))


@app.route('/user/<nickname>')
@login_required
def user(nickname):
    user = User.query.filter_by(nickname = nickname).first()
    if user == None:
        flash('User' + nickname + ' not found.')
        return redirect(url_for('index'))
    posts = [
        {'author': user, 'body': 'Test post #1'},
        {'author': user, 'body': 'Test post #2'}
        ]
    return render_template('user.html',
                        user = user,
                        posts = posts)


@oid.after_login
def after_login(resp):
    if resp.email is None or resp.email == "":
        flash('Invalid login. Please try again.')
        return redirect(url_for('login'))
    user = User.query.filter_by(email=resp.email).first()
    if user is None:
        nickname = resp.nickname
        if nickname is None or nickname == "":
            nickname = resp.email.split('@')[0]
        user = User(nickname=nickname, email=resp.email)
        db.session.add(user)
        db.session.commit()
    remember_me = False
    if 'remember_me' in session:
        remember_me = session['remember_me']
        session.pop('remember_me', None)
    login_user(user, remember = remember_me)
    return redirect(request.args.get('next') or url_for('index'))
