Key Topics dispatch, mixins, inheritance
Output CBV system + demo views

Learning Objectives

By completing this project, you will:

  1. Implement a base View class with method dispatch.
  2. Add as_view() adapters for routing.
  3. Create mixins for auth and context.
  4. Build generic ListView and DetailView.
  5. Explain CBV vs function-based trade-offs.

The Core Question You’re Answering

“How do class-based views turn repeated patterns into reusable abstractions?”

Concepts You Must Understand First

Concept Why It Matters Where to Learn
Method dispatch Map HTTP verbs Django CBV docs
MRO Mixins order matters Python MRO docs
Generic views Reduce boilerplate Django CBV docs

Project Specification

What You Will Build

A CBV system with dispatching, mixins, and generic views integrated into your router.

Functional Requirements

  1. View.dispatch routes to get/post.
  2. as_view() returns a callable.
  3. Auth mixin blocks unauthenticated users.
  4. ListView and DetailView render templates.
  5. 405 responses for unsupported methods.

Questions to Guide Your Design

  1. What should happen if get is not implemented?
  2. How will you pass context to templates?
  3. Which mixin should run first?

Interview Questions

  1. What is as_view() for?
  2. How does Django dispatch CBVs?
  3. What are pros/cons of mixins?

Testing Strategy

  • GET routes map to get().
  • 405 when unsupported.
  • Mixins run in correct order.

Extensions

  • Add FormView and UpdateView.
  • Add caching mixins.
