## Mix `Path`, `Query` and body parameters

First, of course, you can mix `Path`, `Query` and request body parameter declarations freely and **FastAPI** will know what to do.

And you can also declare body parameters as optional, by setting the default to `None`:

    ```Python hl_lines="18-20"
    {!> ../../../docs_src/body_multiple_params/tutorial001_an_py310.py!}
    ```

{!../../../docs_src/path_operation_advanced_configuration/tutorial004.py!}
```

## Additional Responses

You probably have seen how to declare the `response_model` and `status_code` for a *path operation*.

That defines the metadata about the main response of a *path operation*.

You can also declare additional responses with their models, status codes, etc.

    override
    fun execute(context: ComponentMetadataContext) = context.details.run {
        if (loggingModules.contains(id.name)) {
            allVariants {
                withCapabilities {
                    // Declare that both log4j and log4j-over-slf4j provide the same capability
                    addCapability("log4j", "log4j", id.version)
                }
            }
        }
    }
}
