2. Django REST Framework - Serializers & Response objects | Browsable API | Tutorial

   This lesson introduces serializers, highlighting their importance for converting complex Django data types (like querysets and model instances) into Python primitives that can be rendered into formats like JSON. It also covers the inverse process of deserialization. Additionally, introduces the Browsable API and the Response object provided by Django REST Framework.

3. Django REST Framework- Nested Serializers, SerializerMethodField and Serializer Relations | Tutorial

   In this lesson, we delve into techniques for serializing complex data structures involving related models in Django REST Framework. We will learn how to represent one-to-many relationships by embedding serialized data of related models within the parent object's representation. Additionally, we will explore how to add custom, read-only fields to our API responses using SerializerMethodField and examine different ways to represent foreign key relationships.

4. Django REST Framework - Serializer subclasses and Aggregated API data | Tutorial

   This lesson provides an overview of how to create generic serializers in Django REST Framework that are not tied to specific models. It demonstrates how to aggregate data from different sources (in this case, a database) and return it as a single JSON response to clients.

5. django-silk for Profiling and Optimization with Django REST Framework | Tutorial

   This lesson focuses on using the Django Silk package to profile and optimize Django REST Framework APIs, with a particular emphasis on optimizing database queries for better performance. The lesson demonstrates how to install and configure Django Silk, use it to inspect HTTP requests and their associated SQL queries, and identify and resolve database query performance issues like the N+1 problem using Django's prefetch_related feature.

6. Django REST Framework - Generic Views | ListAPIView & RetrieveAPIView | Tutorial

   In this lesson, we explore the power of class-based generic views in DRF. Generic views in DRF offer a streamlined approach to building common API endpoints by abstracting common idioms and patterns in view development. This lesson focuses on read-only generic views, specifically ListAPIView and RetrieveAPIView, demonstrating how they simplify the process of creating API views that closely map to database models for common CRUD operations.

7. Django REST Framework - Dynamic Filtering | Overriding get_queryset() method | Tutorial

   In this lesson, we will explore how to dynamically filter data returned by Django REST Framework generic API views, specifically focusing on overriding the get_queryset() method. This technique allows you to customize the set of objects retrieved from the database based on dynamic information, such as the currently authenticated user.

8. Django REST Framework - Permissions and Testing Permissions | Tutorial

   This lesson introduces permissions in Django REST Framework and demonstrates how to create and apply them to generic view classes. It addresses the issue of unauthorized access to user-specific data and explains how permissions, in conjunction with authentication, control access to API endpoints.

11. Django REST Framework - Customising permissions in Generic Views | VSCode REST Client extension | Tutorial

    This lesson explores how to customize permissions in Django REST Framework generic views on a case-by-case basis. It addresses scenarios where different permissions are required for different operations (e.g., GET vs. POST requests) on the same API endpoint. The lesson focuses on overriding the get_permissions method to dynamically apply permission classes based on the type of request. It also introduces the REST Client extension for VS Code as a convenient tool for testing APIs.

12. Django REST Framework - JWT Authentication with djangorestframework-simplejwt | Tutorial

    In this lesson, we explore how to add JSON Web Token (JWT) authentication to a Django REST Framework (DRF) API using the djangorestframework-simplejwt package. This method allows clients to authenticate by sending a token in an HTTP header, which the API can then verify to permit or deny access to specific endpoints.

13. Django REST Framework - Refresh Tokens & JWT Authentication | Tutorial

    In this lesson, we will explore how to use refresh tokens in conjunction with JSON Web Token (JWT) authentication within a Django REST Framework API, utilizing the Simple JWT package. This lesson focuses on understanding the token refresh mechanism provided by the Simple JWT package.

14. Django REST Framework - Updating & Deleting data | Tutorial

    This lesson explains how to implement update and delete functionality in a Django REST Framework API using generic views. It focuses on utilizing pre-built classes provided by the framework to streamline the process of building API endpoints for modifying single model instances.

15. drf-spectacular - Django REST Framework API Documentation | Tutorial

    In this lesson, we explore how to generate API documentation for Django REST Framework (DRF) APIs using the drf-spectacular library. The video emphasizes the importance of sharing API structure with various stakeholders like frontend and mobile developers to facilitate seamless integration.

16. django-filter and DRF API filtering - Django REST Framework | Tutorial

    This lesson provides an introduction to applying filtering, searching, and ordering to API response data in Django REST Framework (DRF) using the django-filter package. It emphasizes the importance of allowing clients to filter data to improve API performance by reducing unnecessary data transfer and potentially optimizing database queries.

17. SearchFilter and OrderingFilter in Django REST Framework | Tutorial

    In this lesson, we explore how to enhance your Django REST Framework APIs by adding functionalities for searching and ordering data using URL parameters. These features allow clients to easily filter and sort API responses according to their needs.

18. Writing Filter Backends in Django REST Framework! | Tutorial

    This lesson demonstrates how to create custom filter backends in DRF. It explains the process of extending the base FilterBackend class to implement specific filtering logic that goes beyond the functionalities provided by the built-in filter backends like DjangoFilterBackend, SearchFilter, and OrderingFilter.

19. API Pagination - Django REST Framework | PageNumberPagination & LimitOffsetPagination | Tutorial

    When building APIs, especially those dealing with a large amount of data, returning all records in a single response can lead to performance issues and a poor user experience. Pagination addresses this by dividing the data into smaller, more manageable pages. This lesson explores how to implement pagination in Django REST Framework using two primary methods: PageNumberPagination and LimitOffsetPagination.

20. Viewsets & Routers in Django REST Framework | Tutorial

    In this lesson, we explore ViewSets and Routers in Django REST Framework, which are powerful tools for building efficient and well-structured APIs. ViewSets allow you to combine the logic for a set of related views into a single class, while Routers automatically handle the URL configuration for these ViewSets.

21. Viewset Actions, Filtering and Permissions in Django REST Framework | Tutorial

    This lesson explores how to leverage viewsets in Django REST Framework to build powerful APIs. It covers essential techniques for filtering data, defining custom actions, and managing permissions at different levels within a viewset.

22. Viewset Permissions | Admin vs. Normal User in Django | Tutorial

    This lesson explores how to implement role-based permissions within Django REST Framework viewsets. It demonstrates how to differentiate between administrators and regular users to control access to data and actions. The focus is on modifying the behavior of an OrderViewSet to ensure users can only interact with their own orders, while administrators retain full access to all orders.

23. Creating Nested Objects | Overriding serializer create() method in Django REST Framework | Tutorial

    In this lesson, we explore how to handle the creation of related objects when a POST request is made to a Django REST Framework server. The primary focus is on implementing writable nested representations, allowing clients to send data for both a main object and its associated nested objects in a single request. The lesson uses the example of creating an Order along with its OrderItems.

24. Updating Nested Objects | ModelSerializer update() method in Django REST Framework | Tutorial

    This lesson explores how to update nested objects using the update() method within Django REST Framework's ModelSerializer. It builds upon the concept of writable nested representations introduced through overriding the create() method.

25. ModelSerializer Fields - Best Practices | Tutorial

    This lesson provides an overview of how to specify fields in Django Rest Framework's ModelSerializer using the fields and exclude attributes within the Meta class. It discusses different approaches and recommends the best practice for defining serializer fields.

26. Caching with Redis and Django! | Tutorial

    This lesson explores techniques for improving the performance of Django APIs by implementing caching with Redis. It covers setting up Redis with Docker, integrating it with Django using the django-redis package, caching API responses, and invalidating the cache when underlying data changes.

27. Django & Redis - Vary Headers to Control Caching Behavior | Tutorial

    This lesson explores how to use Vary headers in a Django application with Redis as the cache backend to control caching behavior based on request headers, specifically focusing on creating per-user caches.

28. API Throttling with Django REST Framework | Tutorial

    This lesson provides an overview of API throttling in Django REST Framework, which is the process of limiting the number of requests that a single user can send to an API over a specific period of time. Throttling helps to manage API usage, especially for public APIs with different tiers, by preventing overuse. It's similar to permissions in that it determines if a request should be authorized, but unlike permissions, throttling indicates a temporary state and controls the rate of requests. Django REST Framework offers built-in tools for implementing throttling.

29. Testing APIs with Django REST Framework | Tutorial

    This lesson introduces testing tools provided by Django REST Framework to improve support for making API requests and integration with Django REST Framework. It highlights how Django REST Framework extends Django's existing test framework with helper classes.
