Learn PYRAMID-REST with Real Code Examples
Updated Nov 27, 2025
Architecture
Pyramid app as central WSGI application
View/resource mapping via URL dispatch or traversal
Request and response pipeline with events and predicates
Authentication/authorization policies applied per route
Optional add-ons for serialization, validation, and caching
Rendering Model
Client sends HTTP request
Route or traversal matches request to resource
View callable executes business logic
Response serialized to client format (JSON/XML)
Authentication and predicates applied as needed
Architectural Patterns
URL dispatch or traversal-based routing
Resource/view mapping for REST endpoints
Middleware/events for request/response lifecycle
Pluggable authentication and authorization policies
Integration with ORM, caching, and validation add-ons
Real World Architectures
