Using 404 Not Found when item is deleted

204 No Content responses must not include a message body. Using .send('Deleted') with 204 is incorrect. The code should set status 204 and send no content.

Common Mistakes

Sending data with 204 status

Using raw 204 integer instead of status constant

Omitting content_type or using wrong type

In Django REST Framework, to send a 204 No Content response, use status.HTTP_204_NO_CONTENT, no data (None), and a content type like 'application/json'.
