• API Schema Generation - Produces API documentation by inspecting URL patterns and view logic.
• API Versioning - Maintains backward compatibility by supporting multiple API iterations within the same application.
• Field Configuration - Sets field attributes like read-only status, required presence, and default values.
• Limit Offset Pagination - Django REST Framework paginates results using limit and offset query parameters to control the number of items returned and the starting position.
• Nested Serializers - Embeds related model instances directly within a parent object's representation.
• Response Inspection Tools - Django REST Framework accesses response metadata including raw data, status codes, rendered content, and renderer-specific context information during the rendering lifecycle.
• Response Renderers - Allows defining custom media types and rendering logic for API responses.
• Token Authentication - Authenticates requests using simple token strings for persistent client access.
• UI Automation - Interacts with live application endpoints using a standard HTTP client to verify interface responses.
• API Routing Extensions - Django REST Framework defines specific API URL structures by subclassing existing routers and creating custom URL templates.
• API Schema Generators - Generates structured OpenAPI definitions by introspecting view attributes and serializer fields.
• Composite Fields - Validates complex data structures like lists, dictionaries, and JSON objects.
• Cursor Pagination - Paginates large datasets using opaque cursors to ensure consistent views and efficient performance.
