Lesson 24 — Class-based view dispatch

One class, one method per HTTP verb

Browsers send requests with a method: GET to read a page, POST to send a form. A Django class-based view has a dispatch() that looks at the method and calls get() or post(). If the class has no such method, the answer is 405 Method Not Allowed.

getattr(obj, "get", default) finds a method by name, or returns default if it does not exist.

Note: the exercise runs in your browser without Django installed, so it is a small plain-Python simulation of what Django does for you.

Why it matters: this is exactly how Django's View class works inside — and it keeps read and write logic apart.
