### Understand that Code { #understand-that-code }

The important point is just using **`AfterValidator` with a function inside `Annotated`**. Feel free to skip this part. 🤸

But if you're curious about this specific code example and you're still entertained, here are some extra details.

#### String with `value.startswith()` { #string-with-value-startswith }

In this case, you can disable the response model generation by setting `response_model=None`:

{* ../../docs_src/response_model/tutorial003_05_py310.py hl[7] *}

This will make FastAPI skip the response model generation and that way you can have any return type annotations you need without it affecting your FastAPI application. 🤓

This section is useful only to a handful of people, team members with permissions to manage the repository. You can probably skip it. 😉

...so, you are a [team member of FastAPI](./fastapi-people.md#team){.internal-link target=_blank}? Wow, you are so cool! 😎
