Why does it keep saying that it didn't find all 3 links in rendered template? Please help me.

This is the task I'm trying to do: In the nav tag in layout.html, add three links:

A link to logout() with the text "Sign Out" A link to 'login()' with the text "Sign In" A link to 'register()' with the text "Sign Up"

lunch.py
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'


@login_manager.user_loader
def load_user(userid):
    try:
        return models.User.select().where(
            models.User.id == int(userid)
        ).get()
    except models.DoesNotExist:
        return None


@app.before_request
def before_request():
    g.db = models.DATABASE
    g.db.connect()
    g.user = current_user


@app.after_request
def after_request(response):
    g.db.close()
    return response


@app.route('/register', methods=('GET', 'POST'))
def register():
    form = forms.SignUpInForm()
    if form.validate_on_submit():
        models.User.new(
            email=form.email.data,
            password=form.password.data
        )
        flash("Thanks for registering!") 
    return render_template('register.html', form=form)


@app.route('/login', methods=('GET', 'POST'))
def login():
    form = forms.SignUpInForm()
    if form.validate_on_submit():
        try:
            user = models.User.get(
                models.User.email == form.email.data
            )
            if check_password_hash(user.password, form.password.data):
                login_user(user)
                flash("You're now logged in!")
            else:
                flash("No user with that email/password combo")
        except models.DoesNotExist:
              flash("No user with that email/password combo")
    return render_template('register.html', form=form)

@app.route('/secret')
@login_required
def secret():
    return "I should only be visible to logged-in users"

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


@app.route('/')
def index():
    return render_template('index.html')
templates/layout.html
<!doctype html>
<html>
<head>
<title>Lunch</title>
</head>
<body>

<nav>
  <ul>
    <li><a href="logout()">Sign Out</a></li>
    <li><a href="login()">Sign In</a></li>
    <li><a href="register()">Sign Up</a></li>
  </ul>
</nav>

<div class="messages">
{% with messages = get_flashed_messages() %}
{% for message in messages %}
<div>{{ message }}</div>
{% endfor %}

Hey Tim Good 👋

You'll want to have a look at the values you're providing to the href attributes. Instead of setting them to be strings similar to the route function names you'll want to dynamically create the URLs using the url_for function 🙂

For example

<a href="{{ url_for('logout') }}">Sign Out</a>

Hope this helps!
