Overview/Description

In this 14-video course, titled "User Authentication in Flask Applications," you will begin with an introduction to SQL Alchemy, then install it and use it to connect the Flask application—a widely used web framework written in Python language—to a SQLite database. You will observe how to use SQL Alchemy to generate relational database tables for each model defined in an application; execute queries against tables by using a SQL Alchemy model; and how to structure a Flask application for maintenance. Then you will modify import statements to account for restructuring of Flask app and test that functionality has not been affected. Use Bcrypt package to generate hashes of passwords so that they can be stored securely, and create a bespoke validator for fields in your WTForms. Next, learn how to enable users to log in and log out of a Flask application. You will access and display the three most recent reviews posted on your Flask website; learn how to test feedback display functionality; and display images in your Flask website.
