# Hands-on Flask-05 : Handling SQL with Flask Web Application
Purpose of the this hands-on training is to give the students introductory knowledge of how to handle forms, how to connect to database and how to use sql within Flask web application on Amazon Linux 2 EC2 instance.
## Learning Outcomes
At the end of the this hands-on training, students will be able to;
- install Python and Flask framework on Amazon Linux 2 EC2 instance.
- build a web application with Python Flask framework.
- handle forms using the flask-wtf module.
- configure connection to the `sqlite` database.
- configure connection to the `MySQL` database.
- work with a database using the SQL within Flask application.
- use git repo to manage the application versioning.
- run the web application on AWS EC2 instance using the GitHub repo as codebase.
## Outline
- Part 1 - Write a Sample Web Application with SQLite and database implementation on GitHub Repo
- Part 2 - Write same application with MySQL
- Part 3 - Install Python and Flask framework on Amazon Linux 2 EC2 Instance using RDS
## Part 1 - Write a Sample Web Application with SQLite and database implementation on GitHub Repo
- Write an application with database implementation using `SQLite` and save the complete code as `app-with-sqlite.py` under `hands-on/flask-05-handling-sql-on-ec2-linux2` folder.
- configure required environmental variables for SQLite
- drop users table if exists, create new users table and add some rows for sample
- Execute sql commands and commit them
- Write a function named `find_emails` which find emails using keyword from the user table in the db,
- and returns result as tuples `(name, email)`.
- Write a function named `insert_email` which adds new email to users table the db.
- Write a function named `emails` which finds email addresses by keyword using `GET` and `POST` methods,
- using template files named `emails.html` given under `templates` folder
- and assign to the static route of ('/')
- Write a function named `add_email` which inserts new email to the database using `GET` and `POST` methods,
- using template files named `add-email.html` given under `templates` folder
- and assign to the static route of ('add')
- Add a statement to run the Flask application which can be reached from any host on port 80.
## Part 2 - Write same application with MySQL
- Create an RDS database and use it as database of application
- Please write same application that was given in Part2 with MYSQL
- commit your code and push it to your GitHub repo
- Launch an Instance and pull your files in to it
- Run your application on EC2
## Part 3 - Install Python and Flask framework on Amazon Linux 2 EC2 Instance
- Launch an Amazon EC2 instance using the Amazon Linux 2 AMI with security group allowing SSH (Port 22) and HTTP (Port 80) connections.
- Connect to your instance with SSH.
- Update the installed packages and package cache on your instance.
- Install `Python 3` packages.
- Check the python3 version
- Install `Python 3 Flask` framework.
- Install `flask_mysql`.
- Run application with Python
