This should all feel very familiar - it is not a lot different from working with regular Django views.
Notice that we're no longer explicitly tying our requests or responses to a given content type. `request.data` can handle incoming `json` requests, but it can also handle `yaml` and other formats. Similarly we're returning response objects with data, but allowing REST framework to render the response into the correct content type for us.
