2. Course Overview • Objective: Learn how to develop and expose RESTful APIs with Django and Django REST Framework. • Audience: Developers with basic Python knowledge looking to expand into web applications and REST API development. • Prerequisites: Basic understanding of Python and Django https://nareshit.com/courses/django-online-training

3. Agenda • Introduction to Django and RESTful APIs • Setting up Django and Django REST Framework • Building APIs: Endpoints, Serializers, and Views • Authentication and Permissions • Advanced API Features: Pagination, Filtering, and Versioning • Testing and Deploying APIs • Final Project and Hands-On Exercises https://nareshit.com/courses/django-online-training

4. What is Django? • Definition: Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. • Key Features • MVC (Model-View-Controller) structure • Built-in admin interface • ORM (Object-Relational Mapping) system • Middleware support https://nareshit.com/courses/django-online-training

5. Understanding RESTful APIs • What is REST? • Representational State Transfer (REST) is an architectural style for creating scalable web services. • Based on HTTP methods: GET, POST, PUT, DELETE, etc. • Why Use REST with Django? • Seamless integration with Django’s ORM • Allows for a standardized, decoupled architecture https://nareshit.com/courses/django-online-training

6. Setting Up DjangoREST Framework (DRF) • Installing Django and DRF • Commands: pip install django and pip install djangorestframework • Setting Up a Django Project • django-admin startproject projectname • Adding DRF to Django Project • Update INSTALLED_APPS with 'rest_framework' https://nareshit.com/courses/django-online-training

7. Building Your First APIEndpoint • Define the Model : Create Django models to represent data. • Create a Serializer: • Purpose: Convert Django model instances to JSON format and vice versa. • Example: from rest_framework import serializers • Define Views and URL Patterns: • Use Django views to handle API requests • Set up URL routing for API endpoint https://nareshit.com/courses/django-online-training

8. API Authentication & Permissions • Types of Authentication in DRF: • Basic, Token, and Session Authentication • Permissions: • Configure who can access which resources • Use built-in permissions (IsAuthenticated, IsAdminUser) or custom permissions https://nareshit.com/courses/django-online-training

9. Advanced API Features • Pagination: Limit the number of items returned in API responses • Filtering: Retrieve specific data based on parameters • Versioning: Enable version control for APIs to support backward compatibility https://nareshit.com/courses/django-online-training

10. Testing Your APIs • Why Testing is Important • Ensures reliability and prevents regressions. • Tools for Testing • Django’s built-in testing framework • DRF test utilities and tools like Postman for API testing https://nareshit.com/courses/django-online-training

11. Deploying Django REST APIs • Hosting Options: Deploy APIs on platforms like Heroku, DigitalOcean, or AWS. • Configuring for Production: • Secure settings, database configurations, and static files management. • Containerization: Use Docker for consistent deployment across environments. https://nareshit.com/courses/django-online-training

12. Project and Hands-On Exercises • Final Project: Develop a small application with multiple endpoints, CRUD operations, and authentication. • Hands-On Exercises: • Creating serializers and views • Adding custom permissions • Integrating with a front-end application (optional) https://nareshit.com/courses/django-online-training
