Flask Full Series - Web Application Development with Python - Flashes & Validations - Episode 10

Flask Python
#Flask #Python #FlaskTutorial

👍Welcome to my Python Flask tutorial

In this episode, we will learn how to display dynamic messages/alerts to our clients, and as well as we will write some advanced validations.
By saying advanced validations, we probably want to look for a way what will happen if our clients will try to register with a username that already exists in our database.
So this might be confusing in the first look, but I hope the explanations will make it easy for you!

Throughout this series, I am going to go deeper into each topic by developing a real website that simulates an open market that different users can purchase items, including a budget system for each user.

Welcome to the tenth episode everyone, in this episode we are going to display nicer alerts to our clients.
And as well as writing some more complex validations to add some strength to our registration form, dealing
with cases when our users trying to register with an existing username.
Enjoy:)

Best part is your typing the code and also catching the errors on the fly, which is very helpful. Thanks for your efforts man.
