Definition: Function Based View (FBV)

A view that is too small to be part of a Class.

When to use

• The view handles a single action (one HTTP method, one response).

• The logic is simple enough that a class with get/post/put methods would be overkill.

• You don’t need shared state across multiple actions.

Workflow: Writing an FBV

1. Define a function that takes request as the first parameter.

2. Return an HttpResponse (or render, redirect, JsonResponse).

3. Decorate with @require_http_methods if you want to restrict allowed methods.
