Build a Simple Student Management System with Python RESTful API
This tutorial walks through designing a RESTful API, creating a school‑teacher‑student CRUD system, modeling the database schema, structuring the Flask project, and using tools like Postman and curl to test the Python backend, with code snippets and diagrams illustrating each step.
Python: One-Week Notes
This article abstracts a portion of an actual project’s API into a simple “Student Management System” example, demonstrating CRUD operations for school, teacher, and student information via a RESTful API.
1. Restful API Design
It covers URL design and status‑code conventions, illustrating POST, GET, PUT, and DELETE requests with corresponding response diagrams.
2. Database Design
The example shows table design, field types, and presents the School table schema.
3. Development
Directory structure considerations focus on coupling and extensibility. Database operations are separated from business logic, using SQLAlchemy for CRUD wrappers and Flask to define API endpoints. Sample code snippets for adding records and handling POST requests are provided.
4. Tools
Common tools for sending RESTful requests include Postman (Chrome extension), RESTClient (Firefox extension), and command‑line curl.
5. Result Presentation
Requests flow from API → database CRUD → JSON response with status codes, and the inserted data is displayed.
Future articles will discuss testing the project with unittest, mock, tox, coverage, and nose.
