รหัสสถานะและคลาสย่อยของ HttpResponse

Every response carries a status code. The number tells the browser if things went well, moved, or broke. 🚦

Codes in the 2xx range mean success. 200 is the everyday OK, and 201 signals that something new was created.

A 3xx code tells the browser to go elsewhere. 301 is a permanent move, while 302 is a temporary redirect.

The 4xx codes blame the request. 404 means not found, 403 means forbidden, and 400 means a bad request.

Use JsonResponse to send data as JSON. Pass a dict and Django sets the right content type for you.

The redirect shortcut returns a 302 to another URL or view name, so users land exactly where you want them.

Behind redirect sits HttpResponseRedirect. Give it a URL and it builds the 302 response for you directly.

For a permanent move, use HttpResponsePermanentRedirect, which sends a 301 so browsers remember the new address.

Raise Http404 when a record is missing. Django catches it and shows your not-found page with a 404 code.

The get_object_or_404 helper fetches a row or raises Http404 automatically, saving you a manual check.

Choosing the right subclass sets a correct status with no manual numbers, keeping your views clear and honest.

Which response sends JSON with the correct content type?

Status codes and HttpResponse subclasses like JsonResponse, redirect, and Http404 let your views answer clearly. 🚀
