Flask is a framework that is widely used to create APIs in Python. Flask is a simple yet powerful web framework that is designed to help us get started quickly and easily, with the ability to scale up to complex applications.
Flask is called “micro” because it was built with a simple but extensible core.
SQLAlchemy is an Object Relational Mapper (ORM).
Flask-SQLAlchemy is fun to use, incredibly easy for basic applications, and readily extends for larger applications.
For the complete guide, check out the API documentation on the SQLAlchemy class.
First, run the commands below to install the required dependencies:
Create a file and name it app.py. Let’s get to the code.
Create a folder and name it “templates.”
Inside the “templates” folder, create a file and name it home.html, then add the below code.
Inside the “templates” folder, create a file and name it add.html then add the code below.
Inside the “templates” folder, create a folder and name it “extra,” then create a file named _flash.html and add the code below.
In your terminal, run this code to create a database:
Run:
Your app should be up and running locally at http://127.0.0.1:5000/.
Flask uses an ORM (SQLAlchemy) that helps to easily map out a database. This app shows us how to use Flask-Sqlalchemy to easily map out the model.
