Lab 4

Welcome! This week we will be working with user logins and sessions.

1. If you need to install packages into your environment:

   • pip install -r requirements.txt
   • The only new library is passlib

2. Let's start by setting up our DB with Postgres (paying attention to the foreign key):

   • psql: CREATE DATABASE lab5;
   • psql: \c lab5
   • psql: CREATE TABLE users(uid SERIAL NOT NULL PRIMARY KEY, username TEXT NOT NULL, password TEXT NOT NULL);
   • psql: CREATE TABLE posts(pid SERIAL NOT NULL PRIMARY KEY, author SERIAL NOT NULL, content TEXT NOT NULL, FOREIGN KEY (author) REFERENCES users(uid));
   • psql: INSERT INTO users (username, password) VALUES ('Michelle', 'test_pw1');
   • psql: INSERT INTO users (username, password) VALUES ('Jasmine', 'test_pw2');
   • psql: INSERT INTO posts (author, content) VALUES (1, 'test_post_1');
   • psql: INSERT INTO posts (author, content) VALUES (2, 'test_post_2');

   OR

   • psql: \i lab5.sql

3. Everything else we have setup for you in the directory :^). However you will need to uncomment in app.py to discover how this code works out in the app.

4. Tasks

   • Implement Message Flashing.
   • Create your own stylesheet!
   • Replace 'Author number' with real name.
   • Implement dates in your models
   • Test the performance of your app (submit one page report as markdown file):
     • If you can deploy your app to Heroku, check performance and identify bottlenecks: https://developers.google.com/speed/pagespeed/insights/.Add a page with a description of your project. Identify keywords that your projects should be found on the Google search. Do the Search Engine Optimization (SEO). Check the results at:
       • https://www.seobility.net/en/seocheck/
       • https://neilpatel.com/seo-analyzer/
       • https://www.seotesteronline.com/
       • https://sitechecker.pro/
       • https://seositecheckup.com/
       • https://www.woorank.com/
     • If you CANNOT deploy your app to Heroku, check the performance and identify bottlenecks using Developer Tools (Chrome, Firefox, or Safari). Profile your app using the cProfile (check the following tutorial): https://julien.danjou.info/guide-to-python-profiling-cprofile-concrete-case-carbonara/).
