FLASK REST API PROJECT, deployed on Render.com

Deployed in Render.com, check it out 👉 https://flask-rest-api-project-rmrw.onrender.com/
Database transformation: SQLite -> PostgreSQL

Tools and Technologies 🛠️:

Flask, Flask-SQLAlchemy, Flask-JWT-Extended, Flask-RESTX, Python-Decouple, PyTest, SwaggerUI, Werkzeug, Unittest, Render.com, PostgreSQL, DB browser, SQLite

Practicing Include 📚:

• Flask REST API with Python
• Environment variables with Python-Decouple
• JWT Authentication with Flask-JWT-Extended
• Databases with Flask-SQLAlchemy
• How to write Unit Tests with Unittest and PyTest
• Documenting REST APIs with SwaggerUI and Flask-RESTX
• Error Handling with Werkzeug

Basic Setup 🚀

Enter the project folder and create a virtual environment

$ python -m venv env
$ source env/bin/actvate #On linux Or Unix
$ source env/Scripts/activate #On Windows
$ pip install -r requirements.txt #Install all requirements
python runserver.py #Run the server

Changed the id type from integer to serial in the table

Note: While transferring the database schema from SQLite to PostgreSQL, I encountered errors when signing up new users and creating new orders in SwaggerUI. After thorough troubleshooting, I discovered that PostgreSQL does not auto-increment the ID, unlike SQLite. To resolve this, I deleted the transformed old table in HeidiSQL, changed the ID type to serial, created a new table, inserted data, and implemented SQL auto-increment code in the table, which resolved the issue.
