django http response 204

1. In Django, the HttpResponse class is used to create an HTTP response to be sent back to the client.
2. The number "204" in HttpResponse(204) refers to the HTTP status code for "No Content". This status code indicates that the server successfully processed the request, but there is no content to be returned in the response body.
3. When a HttpResponse object is instantiated with the status code 204, it automatically sets the response content to an empty string.
4. The HttpResponse object is then returned from the view function or method, and Django takes care of sending the response back to the client.
5. The client receiving the response with a status code 204 will interpret it as a successful request with no content to display.
6. This status code is often used in scenarios where the client does not need to retrieve any data from the server, but the request was still processed successfully.
