You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank}.

But in some cases you need to return a different status code than the default.

## Use case { #use-case }

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

But if the data didn't exist, you want to create it, and return an HTTP status code of "CREATED" `201`.

     * @return The response data.
     */
    @Override
    public ResponseData execute(final RequestData request) {
        return switch (request.getMethod()) {
        case GET -> doGet(request.getUrl());
        case HEAD -> doHead(request.getUrl());
        case POST -> doPost(request.getUrl());
        default -> throw new CrawlerSystemException(request.getMethod() + " method is not supported.");
        };
    }

        case FileInformation.FILE_ENDOFFILE_INFO:

### Return a Response Directly { #return-a-response-directly }

The most common case would be [returning a Response directly as explained later in the advanced docs](../advanced/response-directly.md){.internal-link target=_blank}.

{* ../../docs_src/response_model/tutorial003_02_py39.py hl[8,10:11] *}

This simple case is handled automatically by FastAPI because the return type annotation is the class (or a subclass of) `Response`.

  /**
   * Returns the node that is adjacent to the origin node along {@code edge}.
   *
   * <p>In the directed case, {@code edge} is assumed to be an outgoing edge.
   */
  N adjacentNode(E edge);

  /**
   * Remove {@code edge} from the set of incoming edges. Returns the former predecessor node.
   *
   * <p>In the undirected case, returns {@code null} if {@code isSelfLoop} is true.
   */
  @CanIgnoreReturnValue

)

// Type identifies the KMS type.
type Type uint

// String returns the Type's string representation
func (t Type) String() string {
	switch t {
	case MinKMS:
		return "MinIO KMS"
	case MinKES:
		return "MinIO KES"
	case Builtin:
		return "MinIO builtin"
	default:
		return "!INVALID:" + strconv.Itoa(int(t))
	}
}

// Status describes the current state of a KMS.
type Status struct {

In this case, you can use `typing.Dict` (or just `dict` in Python 3.9 and above):

## Recap { #recap }

Use multiple Pydantic models and inherit freely for each case.
