Python PostgreSQL Flask GUI App - Build and Publish with Live Database! 🚀

Most full-stack tutorials talk theory for hours before you deploy anything — but in this one: we’re building, learning and publishing a fully functional GUI app in 20 minutes!! ⏰ In this hands-on tutorial, we take a static "Hello World" webpage (02:47) and transform it into a beautiful Flask and PostgreSQL dynamic application with a proper SQL database (03:07). A production ready app that you can publish effortlessly (17:52) and share with the world! 🌍🚀 By the end of this video you'll have more than just code — you'll have you own production-ready social media app running live on a hosting platform named Sevalla — for free!! 😱😱😱 (checkout pinned comment for more detail) ⭐ Try Sevalla for FREE: https://sevalla.com/?utm_source=pytho... 📽️ Check out my full Python GUI Apps series:    • GUI Apps Simplified   ⚙️ Code Resources & Starter Files: ⭐ Full Project Code & Templates: https://github.com/MariyaSha/Flask_Po... ⏰ Timestamps ⏰ 01:03 – Clone Starter Files 01:36 – Flask Project Structure 02:01 – Environment Setup 03:07 – Creating Live PostgreSQL Database on Sevalla 05:30 – SQL Tables & CSV Import 09:32 – Python to PostgreSQL Connection 13:45 – Dynamic Profiles in Flask 17:02 – User Routes & Navigation 18:01 – Environment Variables & Secrets 17:52 – Deploying with Sevalla 21:35 – Fixing Deployment Errors 22:05 – Final Live Website Demo 👀 What You’ll Build: A social-media-style Flask web app A live PostgreSQL database Dynamic user profiles pulled from SQL A fully deployed public website 📚 What You’ll Learn: How full-stack Flask web apps actually work Creating and structuring a PostgreSQL database Importing CSV data into SQL tables Primary Keys, NOT NULL, VARCHAR made easy Connecting Python to PostgreSQL using psycopg Turning static HTML into dynamic database-driven pages Creating dynamic user routes (/user/username) Navigation bars with database loops Environment variables & protecting secrets Deploying a full website with GitHub integration Reading deployment logs & fixing real errors 📽️ Related Videos: ⭐ Flask Quickstart for Beginners:    • Simple Web App with Flask and Heroku - Pyt...   ⭐ Install WSL & Conda:    • My Go-To Python Setup! 🐍 WSL + Conda Minif...   💻 Environment Setup: -------------------------------------------- conda create -n social_env python=3.12 flask conda activate social_env pip install psycopg 🗄️ Example SQL Table Creation: -------------------------------------------- CREATE TABLE user_profiles( username VARCHAR(20) PRIMARY KEY, full_name TEXT NOT NULL, photo_path TEXT, bio TEXT, country TEXT, date_of_birth DATE NOT NULL ); ⚙️ Example Database Connection: -------------------------------------------- import psycopg with psycopg.connect(DB_URL) as connection: cursor = connection.cursor() cursor.execute("SELECT * FROM user_profiles;") results = cursor.fetchall() If you’ve ever felt intimidated by databases or backend development — this video will change that.
