Been working on creating a web app using flask. Was following this tutorial: [this video] My app is a banking app unlike in the video. At this point in my project I am past the video and am trying to create a page where users can view bank accounts that were created by them after they have been stored in the DB. Using Jinja I tried a for loop to get the accounts associated to a specific user. In the video the guys uses a very similar for loop {% block content %} <div class="container py-3 p-3 my-3 border"> <h3 style="text-align:Center">Your Accounts</h3> <form name="banks"> {% for bank in account.bank_accounts %} <label for="banks">Choose an Account</label> <select id="banks" name="banks"> <optio

I'm following this tutorial from tech with tim [this video] about flask so I could understand some of the basics of flask, everything was going ok until I tried to log in a user and it gave a Nonetype error, I don't know what I did but then changing variable names it gave me a BaseQuery has no attribute 'password' , I've been changing everything I could think about from the db model file and the auth file and also the login html file but it didn't work, this are the files I think are the problem: from auth.py: from flask import Blueprint, render_template, request, flash, redirect, url_for from . import db from .models import User from werkzeug.security import generate_password_hash, check_passwor

Cites Jeffee102 · 2021-06 · Stack Overflow · on “login_user() Nonetype object has no attribute is_active with flask_login”

I'm following this tutorial [this video] , when I tried to remember the user logged in after signing up, it doesn't work and shows 'NoneType' object has no attribute 'is_active' error, although, it did registered the user, so I don't know what's happening, it was working before so I know the problem is not in the function itself. Here's the code: def signup(): if request.method == "POST": # getting information into backend email = request.form.get('email') user_name = request.form.get('userName') password_first = request.form.get('passwordFirst') password_confirm = request.form.get('passwordConfirm') # Checking if everything's ok user = User.query.filter_by(email=email).first() if user: flash("Th

So I was following this tutorial on youtube [this video] so the whole code is there and everything was working out perfectly until I accidentally deleted part of the database from the file database.db SQLite format3 � _ �_ �YtablenotenoteCREATE TABLE note ( id INTEGER NOT NULL, data VARCHAR(10000), date DATETIME, user_id INTEGER, PRIMARY KEY (id), FOREIGN KEY(user_id) REFERENCES user (id) )�/�AtableuseruserCREATE TABLE user ( id INTEGER NOT NULL, email VARCHAR(150), password VARCHAR(150), first_name VARCHAR(150), PRIMARY KEY (id), UNIQUE (email) )'; indexsqlite_autoindex_user_1user So the code above is the original database.db code and I deleted the code below and immediately replaced it id INTEG

I am quite a beginner in coding, trying to complete a programming assignment focused on Python. I followed along with Tech with Tim's YouTube video about "Python Website Full Tutorial - Flask, Authentication, Databases & More". Link: [this video] I have followed the code exactly up until 13:36, where he accesses the website url ( [LINK] ). I have tried this, yet I got a 127.0.0.1 refused to connect error. [LINK] I have tried to follow many different tutorials on how to fix this error, but to no avail. I tried: flushing the dns disabling the firewall (real pain) browser HSTS settings I would have tried asking my teacher, but she already got lost when I tried to explain about front-end and back-end

Cites xiaoqi · 2023-07 · Stack Overflow · on “{% block content %} {% endblock %} displayed as text”

I'm going through an online tutorial [this video] on python web development. However, despite double check all the codes are the same, I can't get visual studio to recognize the {% block content %} {% endblock %} as a part of the code. The expected output should be only the contents between {% block content %} {% endblock %} , however, '{% block content %} {% endblock %}' is displayed as plain text on the web page, which is not expected behavior. And the rest of the codes on other templates did not work as well. <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> ... <title> {% block title %}Home{% endblock %} </title> </he
