You could still see some code using it:

//// tab | Pydantic v1

{* ../../docs_src/query_params_str_validations/tutorial004_regex_an_py310.py hl[11] *}

////

But know that this is deprecated and it should be updated to use the new parameter `pattern`. 🤓

## Default values { #default-values }

You can, of course, use default values other than `None`.

$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

If you go to the `/docs` API UI, you will see that it is now updated, and it won't expect to receive the `id` from the client when creating a hero, etc.
