function.

My cookie never updates with anything other than "{}"
import json
from flask import (Flask, render_template, redirect,
url_for, request, make_response)
app = Flask(__name__)
def get_saved_data():
try:
data = json.loads(request.cookies.get('character'))
except TypeError:
data = {}
return data
# Define our routes
@app.route('/')
def index():
data = get_saved_data()
return render_template('index.html', saves=data)
@app.route('/save', methods=['POST'])
def save():
response = make_response(redirect(url_for('index')))
data = get_saved_data()
data.update(dict(request.form.items()))
response.set_cookie('character', json.dumps(data))
return response
app.run(debug=True)
[MOD: added "python" to formatting -cf]

?

ImmuableMultiDict([])
Any idea what step I missed to populate this from the form submission?
Where else does he cover PDB, I'm on a custom track setup by my employer and I don't recall him talking through that on previous videos.

4,693 PointsFound out what was going on with mine. I was trying to make it work with a custom form and was missing the name="name" attribute from my name text input on the form.
