Can a view return a string directly?

A view MUST return an `HttpResponse` object. You cannot simply `return 'Hello'`. You must wrap it: `return HttpResponse('Hello')`.

404 is the standard HTTP status code for 'Not Found'. Using `get_object_or_404()` ensures that if a user tries to access `/post/999/` and post 999 doesn't exist, Django gracefully shows a 404 page instead of crashing with a fatal 500 Server Error.

Should I use FBVs or CBVs?

Function-Based Views (FBVs) are explicit, easy to read, and great for complex logic. Class-Based Views (CBVs) are highly reusable and great for standard CRUD apps. Both are completely valid, and most senior developers use a mix of both.
