Python Flask Basics Character Builder Starting the Builder

In the video at 2:01, I get this error: jinja2.exceptions.UndefinedError: 'function object' has no attribute 'get'

I have tried comparing my script with the script in the video some times. I do not, however, succeed in loading site. This occurred for the first time, when I was at 2:01. Maybe this will ease debugging a lengthier kind of script.

Kindly, Anders.

app.py:

import json
from flask import (Flask, render_template, redirect, 
                   url_for, request, make_response)
from options import DEFAULTS

app = Flask(__name__)



def get_saved_data():
    try:
        data = json.loads(request.cookies.get('character'))
    except TypeError:
        data = {}
    return data




@app.route('/')
def index():
    return render_template('index.html', saves=get_saved_data)


@app.route('/builder')
def builder():
    return render_template(
        'builder.html',
        saves=get_saved_data(),
        options=DEFAULTS
    )


@app.route('/save', methods=['POST'])
def save():
    response = make_response(redirect(url_for('builder')))
    data = get_saved_data()
    data.update(dict(request.form.items()))
    response.set_cookie('character', json.dumps(data))
    return response

app.run(debug=True, host='0.0.0.0', port=8000)

Fixed! The get_saved_data() needed its ().

app.py line 22:

@app.route('/')
def index():
    return render_template('index.html', saves=get_saved_data())
