python flask sqlalchemy

Flask is a lightweight web framework for Python, and SQLAlchemy is a powerful SQL toolkit and Object-Relational Mapping (ORM) library. Combining Flask with SQLAlchemy allows you to build web applications with a robust database backend. In this tutorial, we'll guide you through the process of setting up a basic Flask application with SQLAlchemy for database interaction.
Before we start, make sure you have Python and pip installed on your machine. You can install Flask and SQLAlchemy using the following commands:
Create a new directory for your project and navigate into it. Then, create a virtual environment and activate it:
Now, let's create a basic Flask application with the following structure:
Create a configuration file to store your application configurations:
Create a basic route for your application:
Run the application using this script:
Now, let's create a simple model to represent a User in our application.
Don't forget to import and initialize the db object in the app/__init__.py file:
Now, let's create the database and run the application:
Congratulations! You've set up a basic Flask application with SQLAlchemy and defined a simple model. This tutorial provides a starting point for building more complex web applications with Flask and SQLAlchemy. Explore the Flask and SQLAlchemy documentation for advanced features and best practices.
