AttributeError: '_AppCtxGlobals' object has no attribute 'user' in Flask

Cramer 65

I'm trying to learn Flask following the Flask Mega Tutorial . In part 5 , the login() view is edited as follows:

@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'])
    return render_template('login.html', 
        title = 'Sign In',
        form = form,
        providers = app.config['OPENID_PROVIDERS'])

However, this gave me an AttributeError, I'll paste the StackTrace below. This is exactly the error I pasted from the example source. I do use PeeWee instead of SQLAlchemy, but since this code doesn't do anything with the database, I don't know why this is happening.

Does anyone know what I am doing wrong here?

The tutorial goes further on how to g.userset up:

g.user global

If you are following, you will remember that in the login view function we check g.userto see if the user is already logged in. To achieve this, we will use events in before_requestFlask . before_requestEvery time a request is received , all functions decorated with functions are run before the viewing functions. So this is the correct place to set the g.uservariable (file app/views.py) :

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

this is all. The current_userglobal is set by Flask-Login, so we just put the copied gobject to have better access. This way the logged in user is accessible to all requests, even inside the template.

Your code is obviously missing this before_requesthandler.
