Python Build a Social Network with Flask How to Win Friends Lunch Count

What or where is it wrong? How many lunches? How many followers? How many following?

I have tried so many different combinations, and now it comes back with the same numbers as in the preview. But now it don't show that it's correct?

lunch.py
import datetime

from flask import Flask, g, render_template, flash, redirect, url_for
from flask.ext.bcrypt import check_password_hash
from flask.ext.login import LoginManager, login_user, current_user, login_required, logout_user

import forms
import models

app = Flask(__name__)
app.secret_key = 'this is our super secret key. do not share it with anyone!'
login_manager = LoginManager()
login_manager.init_app(app)
login_manager.login_view = 'login'

    try:
        return models.User.select().where(
            models.User.id == int(userid)

{% block content %}

<dl>
    <dt>Lunches:</dt>
    <dd><!-- total # of lunches ordered -->{{ user.orders.count() }}</dd>
    <dt>Followers:</dt>
    <dd><!-- # of followers. user.followers is a queryset of followers -->{{ user.followers.count() }}</dd>

{% endblock %}

I tried to update this question, but the system did not let me do so. I found out what is wrong, and did not want to give it all away. Maybe we can discuss why it is wrong, but in a more private way to not give away more then I already have done. But then again, maybe everyone else taking this course don't need the hints in this post, so I have nothing to worry about.
