Retrieve and Pass medicine_name Data from Flask-SQLAlchemy to Your Template

Flask-SQLAlchemy is a powerful tool for web development, allowing seamless integration between Flask web applications and SQL databases via SQLAlchemy. When building a web application, one common task might be to retrieve data from your database and pass it to your HTML templates for rendering. In this post, we will walk through how to fetch medicine_name data from a database using Flask-SQLAlchemy and display this data in your template.

Prerequisites

To follow this guide, you should have a basic understanding of:

Python programming

Flask framework

SQLAlchemy ORM

Setting Up Flask-SQLAlchemy

Before diving into data retrieval, ensure you have Flask and Flask-SQLAlchemy installed in your environment:
